How to use the hob media. What you should know about the induction cooker, so as not to be disappointed in the purchase

Until recently, household stoves were divided only according to the principle of operation - gas or electricity, and when buying, there were no questions about how this or that model works. But today, with the development of new technologies and the improvement of household appliances, manufacturers offer consumers the usual units, and modern modernized designs.

Induction cookers are the result of modernization of familiar household appliances. It is worth laying out the facts in more detail about how they work and what they are. Physical action applies only to the hob, the oven is electric with thermal heating elements.

How an induction cooker works

It may seem strange how this type of equipment works, because during the heating process, the dishes are heated, not the burner. The secret lies in the use of a physical phenomenon in the operation of the equipment.

It uses the technology of inducing eddy currents on an installed metal object. Such a result is created by magnetic fields of frequency from 20 to 100 kHz.

Outwardly, it is a glass-ceramic hob, with touch temperature controls. Cooking timers, panel lock buttons are installed on the equipment.

The use of such a technique involves the purchase of special metal utensils. The stoves also work with the usual metal utensils, but then the energy consumption and cooking time may increase.

What is the secret of dishes designed for use on such equipment? The secret lies in the structure of the bottom of the pots or pans. The bottom of such dishes is thick and a layer of ferromagnetic material is laid in its structure.

The hostess may already have such devices in the house. Modern samples are indicated by a special spiral sign, which means compatibility with induction.

Old-style dishes are also used on such equipment, and if there is no sign, then its suitability is checked by applying a magnet to the bottom. If magnetization occurs, then this instance is suitable for further use.

Pros and cons of induction cookers

Appliances with induction heating technology, on average, are more expensive than heated glass-ceramic surfaces. Is it worth it to overpay? And what benefits will the buyer receive after the acquisition?

Advantages:

Reduced level of electricity consumption. The heating temperature is set simultaneously with the inclusion of the burner, no preheating is required, all the voltage is given immediately to the dishes.
The diameter of the dishes is not limited. If for ceramic dishes the selection depends solely on the diameter of the burners, then here the heating occurs only on the contact surface of the installed object. The handles of the dishes do not heat up, the heat generated by the burners is not wasted.
Safely. In the turmoil, at least once every person had a situation where he forgot to turn off the stove. After such cases, the burners burned out, considerable numbers ran up on the indicators of electric meters. Cooktops of this kind prevent dangerous situations from occurring. Without the dishes installed on them, they cannot work and turn off. The panel does not heat up during operation, it heats up only from the bottom of the dish.
Reducing or Enlarging temperature level occurs instantly.
The plate is covered with glass-ceramic. Care for her is available to any housewife using special cleaning products and scrapers.

In contrast to the advantages of induction heating, there are also negative distinguishing features:

High price. Yes, such equipment will cost 1.5 - 2 times more when buying, but you should think about the future reduction in electricity consumption. A properly selected stove will pay off in the near future. But choosing expensive samples is also not worth it, the functions stated in the characteristics are not used in everyday life.
If the house did not find suitable dishes, then you will have to update the entire range - pans, pots, stewpans, etc. Kitchen utensils suitable for this type of household appliances are more expensive, which will incur additional costs.

There are not so many disadvantages, and they all relate to the financial side. But once you invest in a purchase, you can save on electricity for several more years.

Problems

Cookers operating on induction heating technology have not been in demand for a long time in the household appliances market. And the reason is not only the high price, but also myths and prejudices.

Harm to the human body

The opinion that the technology incorporated in the principle of operation of the equipment can harm the human body. People feared that the magnetic field created during work affects the internal organs. In order to destroy the false opinions that have developed regarding induction panels, manufacturers compared the power of the generated fields from this device and from a household hair dryer, which housewives use quite often.

The results were incredible. The hair dryer creates a field with an indicator of 2000 micro Tesla, and the hob - 22 micro Tesla - this is almost 10 times less! The strength of such a magnetic field cannot affect human health in any way!

Turning on the stove from any metal object

People believe that any metal object can trigger the burner to turn on and will heat up. This statement is not true.

As already mentioned, for work you need dishes that can be attracted by a magnet, but not all metal kitchen appliances have such qualities.

Sensors built into the slab design are set to a minimum diameter of 8-12cm. In the event that the area of the heated surface is less than this indicator, then heating will not be performed.

Metal objects under the stove heat up

It is an erroneous opinion that the installation of a recessed panel cannot be above other devices or any metal surfaces.

Yes, the generated electromagnetic field, in theory, leads to heating of objects on the surface and under it. This statement took place at a time when induction cookers were just beginning to be produced.

Modern models are equipped with a magnetic heat sink located at the bottom of the hob body. Its purpose is to block the penetration of magnetic fields through the bottom of the case.

Therefore, today manufacturers also produce combined models with ovens, and designed for embedding in kitchen furniture above dishwashers or other equipment.

How to choose an induction cooker

Like other household appliances, induction surfaces have characteristics that can affect the choice of a product in a store - these are design, functional characteristics, manufacturer's name and price.

Design features when choosing stoves include: free-standing equipment in combination with an oven, tabletop or built-in models, the size and shape of the equipment.

Free-standing household appliances with induction heating are rarely found in stores today, no more than 20 copies. Such models do not require additional purchase of ovens, are installed in any free space, do not take up space on the table, and are not built into the countertop.

Desktop devices are equipment with one or two burners, no more. They do not require additional installation conditions, in addition, some models are designed to work under 220W voltage.

The range of built-in models of induction appliances presented in stores is incredibly wide. In online stores, the number of models offered is even greater. Built-in models look attractive complete with all kitchen equipment, do not require a separate place for installation.

The shapes of household appliances are the usual square or rectangular, but there are also hexagonal built-in models. Sizes are able to meet the wishes of any consumer. The main condition, before going to the store for a purchase, is to accurately measure the place where the unit will be installed.

Functional characteristics that require attention when choosing:

the number of burners and their location;
the presence of a combination in the device, induction burners and with a heating element. For some users, the combined device will have a positive effect, because you won’t have to throw out the old dishes, but for others it will serve as a rejection of this model.
touchpad lock, a feature that will protect a home with young children from unpleasant consequences;
safety shutdown, an option in the presence of which the liquid escaping from the pan will provoke the shutdown of the system and burning to the surface will not occur. Shutdown also occurs when foreign objects get on the control panel;
the shutdown timer will allow you to program the stove for the required time, and be distracted by other things. She herself will turn off the burner and notify with a signal that the program is running;
The residual heat indicator indicates that the surface has warmed up from the surface of the cookware. It burns as long as the surface cools, and goes out when it becomes safe;
multi-stage burner power adjustment. a greater number of adjustment steps - makes it possible to more accurately adjust the cooking temperature;
PowerBoost is a function that will increase the power of the included burner at the expense of the neighboring one by 50%;
the keep warm function keeps pre-cooked meals at a predetermined temperature;
the pause function temporarily stops cooking, so that it can be resumed at the touch of a button, keeping all the set cooking modes.
induction without borders allows the installation of kitchen utensils of any diameter on the surface.

Pricing

The cost of induction cookers is affected by: manufacturer, functionality, size, number of burners, design, construction. Before you go shopping, you need to clearly define the requirements for the future main household appliance in the kitchen.

It is not rational to rely only on the popularity of the manufacturer; equipment manufacturers may not advertise their products. Orientation by price may not be relevant either. Stores set prices according to their desires.

It will be correct to take into account the functionality of the model of interest. Additional features increase the price, so you should consider the need for one or another option in your life.

Precautionary measures

An induction cooker is a device that works by means of power from the mains. And like any other electrical equipment, it must be used with care.

The connection must be only to the mains, with the appropriate voltage indicated in the characteristics.
Blocking the air intake panel can cause the equipment to overheat.
The equipment must be protected from water ingress under the housing.
To clean such a device, you must first disconnect it from the network.

Cookers for the kitchen can be different: they can differ in type, control method. Particular attention should be paid to, which have many positive features. They have a stylish exterior design and simple operation. For many, these devices are unfamiliar, for this reason it is worth considering in more detail their main qualities.

Induction cooker model

Instruction manual for induction cooker

An induction hob is used for comfortable cooking. It is important to be able to properly use such a device so that it can last a long time.

Control Panel

For many, a device with an induction device is new and unfamiliar, but there is nothing complicated in it, the main thing is to consider its instructions, application features and general scheme. But the installation is still worth entrusting to a specialist.

How to turn on the induction cooker

You can connect the induction cooker yourself, there are no particular difficulties in this matter. But if you are a beginner and have never encountered devices of this type, then it is better to entrust this task to a specialist.

For induction models, it is worth using dishes with a flat and thick bottom.

After delivery of the device, do not unpack it yourself and touch its important elements. This work should be done by a specialist in front of you. The fact is that the stove may have some damage or be out of order. If you identify any problems yourself, you may void your product warranty.

The standard induction hob is supplied with a cord and a plug for a normal socket. This means that you do not need to buy additional cords and plugs to connect the equipment to the network. But still it is recommended to choose the right outlet into which the device will be connected.

Many people often connect to one of the free outlets, without taking into account its load capacity. Namely, the indicator of its load, which is allowed to be used for this outlet, is not taken into account.

Model with 4 burners

If this important factor is not taken into account, this can lead to several problems:

in the best case, one of the circuit breakers, which is installed in the area of \u200b\u200bthe electrical switchboard, will fail. This usually occurs as a result of a high load on one of the sections of electrical wiring;
If there is no protection for the electrical wiring, then when connecting several lines in one circuit breaker, an overload will occur, which will cause a wiring fault.

In order to avoid all these problems at the time of using the induction cooker, you should carefully study the principle of its operation, as well as find out the indicator of the highest power. It is also worth making sure that the device can be connected to one of the available outlets.

Principle of operation

Be sure to take into account that a standard socket is designed to turn on household appliances with a rated power of not more than 3.5 kW. This indicator corresponds to a load current of 16 A. From this it follows that if the rated power indicator does not exceed this value, then the device can be safely plugged into a regular outlet.

You need to make sure that the section of electrical wiring that feeds the outlet can withstand the applied load of the device. To do this, several important conditions must be taken into account:

the first step is to find out which cable is connected to the outlet, and how it is connected to the rest of the home electrical wiring;
the cable that feeds the outlet must have a cross section of at least 2.5 square meters. mm;
if the cable is connected in a home switchboard, then this type of wiring is able to withstand the current of a home outlet. In these cases, to protect the wiring line, it is required to install a circuit breaker with the required rating;
you can use the cable to power the outlet. It connects to the junction box. It is imperative to take into account the degree of load of other sockets that are connected to this junction box;
the cable that goes from the main switchboard to the junction box must be able to easily withstand the total load of the sockets powered from it. If the connection of the induction cooker in this area will cause an overload, then it is better to choose another outlet for it;
it is necessary to evaluate the technical possibilities of electrical wiring. If it is old or out of order, then connecting a household appliance can lead to serious problems;
it is desirable that the wiring be made of a cable with copper conductors. If the house uses an aluminum cable, then there will be a high probability that the wiring will not be able to withstand the load placed on it;
be sure to pay attention to the condition of the contact connections in the cable connection area in the home switchboard and socket.

Stove use

In order to connect the induction cooker to the electrical network, you should not use extension cords, tees. For safe and protected use, the device must be grounded.

How to use an induction grill oven

When studying induction cookers, you should pay attention to products with a grill. They appeared not so long ago, but managed to gain high popularity among consumers. By means of this device it is possible to prepare meat, fish, vegetables with appetizing and ruddy crust.

Standard grill models usually include the following items:

induction desktop stove;
brazier-grill;
grill stand;
network cord;
instructions for use.

Induction hob with grill

When using this device, you should pay attention to important features:

grill devices are usually produced in a small size, so their use usually does not cause any particular difficulties;
the first step is to remove the film, stickers from the surface and all the constituent elements of the device;
next you need to wipe the hob from the glass-ceramic base, and also clean the brazier;
then the device must be put in place and connected to the mains in the outlet;
the product is recommended to be installed in an area in the kitchen in which there is normal air ventilation, otherwise the smell will accumulate in the room, and soot will form on the furniture;
after the device is installed, you can start using it;
on the instrument panel has buttons that control the device.

A hob with a grill has a high advantage - with it you can cook various treats from meat, fish, vegetables. In the oven, delicious and rich soups are obtained that retain all their nutritional and beneficial properties. All food is heated evenly and does not burn.

Induction models with a grill need to be properly looked after. For this, the following recommendations should be followed:

due to the fact that almost all devices are equipped with a non-stick coating, the grill can be washed manually;
the surface is not recommended to be lowered into water;
the grill should be cleaned with non-abrasive cleaners;
the hob should be washed with a soft sponge or cloth using a cleaning gel;
be sure to clean the vent. From it you need to blow out the debris with a vacuum cleaner.

Remote control

Induction devices are often found on sale, the inclusion and deactivation of which is carried out by a remote control. It greatly facilitates the use of appliances, makes the process of cooking comfortable and enjoyable.

The regulation of the operating panel and oven is simple. Switching on and off is carried out using special buttons on the remote control. There are also other buttons that are designed to control power, temperature and other additional functionality.

Care of induction devices is simple and easy

Cookers that use induction are convenient and multifunctional devices. They fit perfectly into the modern design of the kitchen, but at the same time they fully fulfill their purpose. The main thing is to study the entire process of their application in the instructions.

Everything in this world moves, grows and develops. Does not bypass progress and household appliances. Moreover, this is one of those industries where development is especially noticeable. Washing machines, food processors, microwave ovens and other miracles of modern household appliances cannot but surprise and delight a person.

Pros and cons of induction cookers

And one of these devices is an induction cooker. Once upon a time it was impossible to even imagine how “smart”, safe and convenient a simple kitchen attribute for cooking. The point is not so much in an attractive appearance, which will give the interior additional sophistication, but in convenience and safety. After all, a modern induction hob is able to independently control its work and even manage the cooking process by adjusting the temperature, which allows you to maintain a given cooking mode.

Externally, the inverter (or induction) stove is not much different from the usual electric stove with a panel and touch controls. In fact, they are united only by external similarity. Then what is an induction cooker? This is a kitchen appliance that allows you to cook food, the principle of which is based on the action of an electromagnetic field, which makes it unique. But, like any technical novelty, such a plate has a number of its disadvantages:

Despite the above shortcomings, if they can be called such, this unit has much more advantages:

Any modern technique that works on certain principles and is designed for certain tasks has some kind of variation to cover a large area of human needs. Inverter cookers are no exception. and are also divided into several types, each of which is more preferable in a particular case:

The principle of operation and device capabilities

The hob of the stove is made of a non-magnetic dielectric material, like glass-ceramic. Located just below the surface inductor(therefore, the induction cooker), which has good electrical conductivity and a cylindrical shape.

When turned on, a high-frequency electric current passes through the coil, which, in turn, excites an alternating magnetic field. Going beyond the panel, the magnetic field also captures the dishes located on the surface, made of a material with magnetic properties (cast iron, iron). An electric current is excited in it, which experiences resistance to its movement. As a result, the material of the dishes is heated. Simply put, it is the pot or pan itself that is heating up, not the surface of the hob.

I would like to draw your attention to the fact that if you touch the work surface near the dishes with your hand while the stove is operating, it will be approximately at room temperature. But under a frying pan or saucepan, the temperature is slightly higher. This is because the surface does not heat up by itself, but from the dishes in which we cook. If, for example, the pan is removed, the panel will return to normal room temperature fairly quickly.

All inverter cookers are equipped with a built-in timer, which is quite multifunctional. Let's say it not only limits the amount of energy expended when cooking a dish, but also extremely accurately set various cooking modes. Many models are equipped with a “boiling mode”, which makes it possible, after boiling the dish, to give it a predetermined time to boil, after which the stove will automatically turn off.

Undoubtedly, such "smart" devices equipped with an electronic scoreboard, on which you can see:

Clock;
Power consumption;
temperature;
Time for preparing;
In the event of a sudden shutdown, an error code is displayed to help determine the cause of the failure.

Of course, depending on the brand and model, these parameters can be much wider. There are models in which both induction burners and conventional electric ones are implemented.

Features of induction cookers

I would like to point out some features, which may be interesting and useful for a more accurate idea of \u200b\u200binverter cookers:

It is clear that such things require knowledge of some points in terms of installation:

For this technique, specialized utensils are needed. Of course, you can cook in the usual, but you should know that the hob won't work if your dishes:

Does not conduct electricity;
Conducts current too well;
Less than 5 inches in diameter (≈ 12 cm);
Already overheated (usually ≈ 100 °C).

Otherwise, any material that contains metal will do, so both cast iron and stainless steel are quite suitable for cooking on such stoves.

If you choose dishes with the calculation of use and on "induction", then pay attention to the presence of a special icon that says that such dishes are suitable for these purposes. It looks like a spiral with the inscription "Induction" at the bottom.

Kitchen appliances have recently surprised with their variety and technological innovations. In addition to the usual gas and electric stoves and hobs, induction devices have also appeared relatively recently. What is it, what is their principle of operation and what is interesting in this device - we will talk further.

Technical subtleties

Simply put, an induction cooker or hob is an electrical appliance that works on the principle of electromagnetic induction, known since the 19th century.

If you explain as simply and briefly as possible, then the principle of operation of the induction cooker is as follows:

Inside the device, under a glass or ceramic surface, there is a whole circuit with inductors made of conductive metal (usually copper).
When we turn on the equipment, when current flows from the network, these coils begin to radiate an electromagnetic field.
If a metal object with ferromagnetic properties, such as a pan, is placed on the hob, then this object becomes a conductor, and the field interacts with it. The induction current also passes through the bottom of the pan, experiencing resistance and heating the dishes and their contents.

That is, for the operation of a stove or hob, electrical energy is needed, but such a kitchen assistant cooks food in a slightly different way than a conventional electric stove.

Like any household appliance, induction cookers can have a different set of functions, but even the simplest device has touch controls and an elementary display that shows all the necessary information, for example:

consumed energy;
temperature at each burner;
information about errors in work;
timer.

There is an opinion that the magnetic field emitted by the stove is harmful to humans. However, recent studies have revealed that the radiation power is too low to affect a person and is comparable, for example, with the radiation from a working hair dryer.

Advantages and disadvantages

Like any household appliance, induction cookers have advantages and disadvantages. Let's consider them in more detail.

A photo	Description
	Pros: High efficiency (about 90%). Due to the absence of heat loss, food warms up faster; Security. Since only the dishes and the surface directly below it are heated, it is impossible to get burned, accidentally set fire to or melt an object that has fallen on the stove, and when you turn off or remove the dishes from the burner, the surface cools down in a matter of seconds. if you put small objects, plastic or even metal cutlery on them. Saving. Electricity is consumed much more economically thanks to the built-in programs, and the kettle or milk will not burn out and will not “run away”, since the sensors of the induction panel recognize the temperature of the liquid and turn off the burner. During cooking the air and nearby objects do not heat up, the room will not become hotter, and the plastic handles of the pan will not exude an unpleasant odor as with strong heating; Temperature and cooking time control. Thanks to special sensors, it becomes possible to set the exact temperature and time for cooking, if necessary.
	Minuses: High price. Since such equipment is much more technologically advanced, its price in stores will be higher than that of the usual and simpler gas and electric stoves; Selectivity in dishes. Not all kitchen utensils are suitable for use on an induction hob. Pots, frying pans, stewpans and other utensils must be made of ferromagnetic material (cast iron, iron, steel) and have a sufficiently thick bottom (at least a few millimeters, but preferably not less than a centimeter); Special requirements for network connection. Some types of stoves consume 3 or more kW, therefore, in order to avoid problems with wiring and its subsequent replacement, it is necessary to provide a separate connection of the stove to the switchboard. Otherwise, you will have to change all the wiring with your own hands and fix problems in the stove itself.

Suitable cookware for induction cookers can be easily identified by the box (there must be an icon in the form of a spiral with the inscription "Induction") or simply by attaching a magnet to the bottom. If it is magnetized, then the utensil is suitable.

Separately, we should talk about the issue of savings. When choosing kitchen appliances, in particular stoves, the question often arises: “What is more economical?”. It cannot be answered unequivocally.

If we consider in terms of acquisition cost, then a hob or stove with magnetic induction, even with the simplest functions, will cost 1.5–2 times more than a similar gas or electric one.

But we must not forget that such a device ultimately consumes less energy and allows you to use it rationally, controlling the heating and the time the dishes stay on the stove.

If we take into account the human factor (they left the kettle turned off, just the burner turned on, etc.) and the cost of gas and energy, then in the question “Which is better: electric, induction or gas stove?” - the “induction” will definitely win.

Features of use

As a rule, the instruction manual and other accompanying documentation are always in the box with the equipment itself and contain recommendations for the care and use and the main features of the unit.

Briefly features of stoves with induction:

During cooking, the surface of the stove remains at room temperature, you can safely put cutlery, a napkin, a plastic cup - nothing will melt or heat up.
If the induction hobs are turned on and there are dishes on them, then if you remove them, they will turn off and cool down in just a few seconds.
When choosing a technique, keep in mind that there are hybrid devices in which some of the burners heat up due to the electromagnetic field, and the rest are conventional electric ones.
It is unlikely that something will burn on such a stove.
Touch control is very convenient and is available even for the simplest devices.
If you use all the burners during cooking, then the total power of the stove will still be lower than the declared one and will be evenly distributed over all the burners.
When installing equipment, it is important to observe not only the space for ventilation, but also take into account the distance to other devices, especially metal ones, since induction fields can also affect them.
The surface of the stove needs minimal maintenance, but careless handling and broken dishes with a rough bottom can break its integrity and leave scratches.

Conclusion

Modern technology not only simplifies our life, but also makes it safe and economical. Induction cookers are a modern and high-tech helper in the kitchen that fits perfectly into any interior, concise and does not take up much space.

The principle of operation of induction cookers and hobs, as well as some of the nuances of use, are discussed in the video presented in this article.

When purchasing a new induction cooker, do not rush to connect it to one of the free sockets. In this case, first of all, it is necessary to determine the possibility of connecting this household electrical appliance to a particular section of the wiring and choose the most optimal way to connect it. Consider the question of how to connect an induction cooker.

It should be noted that before purchasing an induction cooker, it is necessary to clarify what load limit is determined for an apartment (house) and evaluate the possibility of operating one or another induction cooker, taking into account its maximum power consumption.

A desktop induction electric stove, as a rule, structurally has a cord and a plug for connecting to a regular household outlet. That is, in this case, there is no need to purchase an additional cord and plug to connect an electrical appliance. But in this case, it is very important to choose the right outlet to turn on the electric stove.

Very often they make a mistake - they turn on the electric stove in one of the free sockets, without taking into account its load capacity, that is, the amount of load that can be plugged into this socket.

In the best case, one of the circuit breakers in the electrical switchboard will turn off - as a result of an overload in one of the electrical wiring sections. But if there is no proper protection of the wiring, for example, if several lines of wiring are connected to one circuit breaker, overload will damage the wiring.

Therefore, before you start using an electric stove, you need to find out its maximum power consumption and make sure that this appliance can be plugged into one of the available outlets. The power consumption is indicated in watts (W) or in kilowatts (kW) in the passport on the body of the electric stove, as well as in the technical specifications in the instruction manual for this household appliance.

It should be remembered that a conventional household socket is designed to turn on household electrical appliances with a rated power of not more than 3.5 kW, which corresponds to a load current of 16 A. That is, if the power consumption of the electric stove does not exceed this value, then it can be plugged into this socket.

First, you need to clarify which cable is connected to the outlet, and how it connects to the rest of the home electrical wiring. The cable that feeds the outlet must have a cross section of at least 2.5 square meters. mm.

If the cable is connected directly to the home switchboard, then such a wiring line can withstand the current of a household outlet, a circuit breaker of the required rating can be installed to protect such a wiring line. This option is the most preferable in terms of reliability.

The second common option is that the cable that feeds the outlet is connected in a junction box. In this case, you need to take into account the loads of other sockets connected to this junction box.

The cable that runs from the main distribution box to the junction box must be able to withstand the total load of the outlets powered from it. Therefore, if the load of the induction cooker is an overload for a given section of the wiring, then to turn it on, you should choose another outlet of the appropriate load capacity.

Secondly, it is necessary to assess the technical condition of the electrical wiring. If the wiring is in an unsatisfactory technical condition, then, accordingly, when a new load is turned on, it may be damaged (See -). In this case, it is necessary to pay attention to the condition of the cable, in particular its insulation.

A cable with copper conductors is preferred, but if old aluminum wiring is installed in the house, then there is a high probability that such a cable cannot withstand the permissible load.

It is also necessary to pay attention to the condition of the electrical wiring contact connections at the cable connection point in the home switchboard, socket, as well as intermediate contact connections in the junction box.

For connecting to the network of an induction cooker. For safe operation of the induction cooker, it must be grounded, that is, plugged into a socket with a working ground.

You also need to pay attention to the condition of the outlet. If the plug of the electrical appliance does not make good contact with the outlet connectors, then such an outlet must be replaced.

The induction hob has a lot of power, it is not connected to an ordinary household outlet, but to a power outlet rated for a current of more than 16 A.

The power socket for connecting the induction cooker is selected according to its load. The total load of the induction cooker can be on average 25-32 A, depending on the number and power of the burners.

In this case, an individual electrical wiring line must be laid to power the induction cooker. The cross section of the cable depends on the load of the induction cooker: for a current of 25 A, a copper cable with a cross section of 4 square meters should be laid. mm, for a load of 32 A - 6 sq. mm.

For safe operation of the induction cooker, the electrical wiring must have a working protective earth. That is, for a single-phase network, a three-core cable must be connected to connect the induction cooker. Accordingly, the purchased power outlet kit with plug must also have a third grounding prong.

If it is not possible to purchase a power outlet of the required power, then as an alternative, you can connect an induction hobinstalled in a mounting box. The terminal block must be capable of withstanding the rated current of the induction cooker connected to it.

As for the cable through which the induction cooker is connected, in this case it all depends on the configuration. If the power cable is included, then it is enough to connect it to the terminal block directly on the induction cooker, and then to the purchased power plug or in the terminal block - depending on the chosen method of connecting the induction cooker.

If the cable is not included, it must be purchased separately. When purchasing a cable, you must pay attention to its cross section - it must correspond to the connected load. It is necessary to purchase a flexible three-core cable with a cross section of 4 or 6 square meters. mm for rated currents 25 and 32 A, respectively.

To avoid errors, it is recommended to connect the cable to the plate itself, as well as to the plug: brown or black - phase conductor, blue - neutral conductor, yellow-green - protective earth conductor.

If the cable is already connected to the terminal block of the electric stove, then it is necessary to check the correct connection. The following terminal markings are usually indicated on the terminals of the induction cooker:

L - phase output or L1, L2 (L3) - phase outputs for two-phase (three-phase) switching;

N - zero output;

PE - connection point for the protective earth conductor.

Two-phase and three-phase connection of the induction cooker

Certain types of induction hobs may have two or three phase electrical connections. If the house is made, then such an electric stove is connected, as recommended by the manufacturer, to two or three phases of the electrical wiring with a four or five-wire cable.

The electric stove is connected to a single-phase household electrical network with a three-core cable, and special jumpers between the phases, which are usually included in the kit, are installed in the terminal block on the induction stove. If there are no jumpers, then the connection to two or three phase terminals is carried out with a wire of the section corresponding to the load of the electric stove.

It should be borne in mind that if a cable for a two- or three-phase connection is included in the kit, then it is not designed for single-phase switching, since with a single-phase connection of the induction cooker, the load on the phase conductor increases to the total load of all phases.

Therefore, when using a four (five) core cable to connect to a single-phase network, two (three) phases on the plate are connected to the cable cores, and at the other end of the cable, when connected to a plug or in the terminal block, the phase conductors are shorted together and connected to one phase of the mains . Or a new three-core cable is purchased, which has sufficient load capacity for single-phase connection of an electric stove.

The process of connecting an induction cooker with an oven is no different from connecting one induction hob. The only difference is the large power consumption, since in addition to the induction hob, the power of the oven is added. Accordingly, it is necessary to correctly select the cable cross-section, as well as a set of power sockets and plugs for connecting the electric furnace to the network.

There are types of induction cookers with an oven, which provide for limiting the maximum power consumption by turning off one of the burners when the oven is in operation. That is, you can operate all the burners of the induction cooker at the same time, but when you turn on the oven, the possibility of turning on one burner is blocked. This option is most suitable for houses with a limited power limit, which does not allow the operation of sufficiently powerful electric stoves.

Protective devices

When connecting an induction hob, it is very important to correctly select the necessary protective devices. To protect the induction cooker, as well as the supply wiring, a circuit breaker is installed. The rated current of the circuit breaker is selected based on the power of the induction cooker. In this case, the nearest higher current value is selected, but the characteristics of the electrical wiring are also taken into account - it must protect all elements of the electrical wiring.

To ensure the safety of the operation of the induction cooker, it is installed in the switchboard, which protects against electric shock, as well as fire in the event of a current leakage through damaged insulation. The RCD must be designed for the rated current, taking into account the possible load on the wiring lines.

For example, if a 32 A circuit breaker is installed on the line, then the RCD should be designed to operate at a higher rated current - by 40 A, since the thermal release of the circuit breaker does not turn off immediately when the current exceeds 32 A, but with some time delay. To protect a person from the negative effect of electric current, the differential current of the residual current device must be no more than 10 mA.

As an alternative, it is possible to use a combined device - that performs the functions of the two above-mentioned protective devices.
