Most modern consumers prefer electric hobs. Connecting this home appliance is often limited to plugging in the plug. Most buyers purchase only the upper working part of the panel, which does not include a cord. For this reason, it is imperative to know how to properly connect a hob without a plug.

Schemes for connecting the hob to the electric meter

To prevent electric shock, the body of the device must be grounded or "zeroed", if it is provided for in the instruction manual.

Step-by-step connection algorithm;

1. The most modern option for connecting a built-in panel is a 4-wire circuit;
2. It is advisable to purchase a cable for connection with a cross section that will not be too large in order to prevent loss of electrical resources. If the cross section is too small (less than 2.5 mm 2), the cable will heat up.
3. On the back side of the panel we find a rectangle of a regular contact connection. Using a screwdriver, four bolts are unscrewed, the cover is removed.
4. After opening the cover, determine the presence of a copper jumper between the black and brown wires, then connect the cable to any of the clamps. If there is no jumper, it must be installed. Secure the cord with a clamp to prevent it from falling out of the terminal box. Loosen the screws.
5. The “ground” wire has a yellow-green color and is always connected first, after which we connect the blue “neutral” wire. Connect the brown or black phase wire last to the corresponding terminal. Tighten the screws.
6. Check the integrity of the contact connections in the terminal and junction box. Strong tension and sagging of the wire is not allowed. If the installation is carried out in an open way, the location near the heating elements is prohibited. It is also not recommended to locate it near gas equipment (gas water heaters, boilers, water heaters).

The choice of cable, machine, RCD for connecting the Electrolux brand panel

The calculation of the choice of the current load of the machine for connecting the hob is calculated as follows:

• a panel with a 220 V power supply consumes 5 kW;
• current loads can be calculated according to Ohm's law;
• therefore, the power consumption indicator of the device will be 5 kW / 220 V = 22.7 A;
• the denomination of machines for the Electrolux model goes in the following sequence - 16/25/30 Amperes.

The implementation of power supply to the hob, where a plug is not provided, it is necessary to install an automatic machine with a rating of 25 Amperes.

The cable is selected taking into account the method of wiring installation - hidden or open. For open wiring, a cable with a cross section of 6 mm 2 is required, for hidden wiring, respectively - 10 mm 2 for copper. For reliability and safety, it is recommended to choose a cable with reinforced or double insulation.

With the open method of wiring, corrugated insulation is used, which protects the wire from mechanical damage and increased heat. In the event of an overload of the supply conductor, the corrugated sleeve provides protection against possible fire, as it prevents combustion. With concealed installation, additional security measures are not applied.

When choosing an RCD, it is necessary to take into account the rated current of the machine, it should be an order of magnitude less. With a machine with a nominal value of 25 Amperes, an RCD is installed at 40 Amperes.

Installing the hob: sequence and rules

Must be carried out in accordance with the following rules and recommendations:

• the hob must be mounted on a horizontal flat surface, ignoring this requirement may lead to deformation of the metal parts of the device and disruption of the ceramic surface.

• screw short screws to standard holes, which are located on the sides;
• for the most even installation of the panel in the kitchen set, it is necessary to level the horizontal surface with a laser level by lightly pressing on the center of the device;
• after complete installation, fix with fasteners. The center plate bolts must remain accessible;
• If the hob is installed without following the instructions in the instruction manual, the efficiency of this appliance may be affected.

Turning on the induction cooker after installation

After installation, it is performed according to important rules:

• before commissioning, the product must be cleaned of dirt, adhesive residues and preservative lubricants using special detergents that do not contain abrasives;
• the stove is switched on by pressing the "Network" button;
• if the panel connection is carried out correctly, then after the voltage is applied, an audible signal sounds;
• after a few hours of operation of the device, an unpleasant smell of burnt rubber or plastic may appear, which soon burns and disappears;
• the inclusion of one of the cooking zones occurs with the help of a button and a power regulator with a graduation from 0 to 9;
• when several cooking zones are working at the same time, the display shows the time countdown on the zone that is closer to the end of the process. The display for adjacent cooking zones flashes.

The installation of the hob should be entrusted to a professional
