Complete modern appliance cord, available in other models of equipment are not provided. The reason is that according to the requirements of the TB to connect these devices relies via pad special design that can withstand high currents. As an exception, may be used with ground socket designed for a limit load currents up to 32 Amps (pictured below).
Characteristics of power line
To connect the appliance is required to organize a separate line on the protected machine 25-32 Ampere. This will require a cable cross-section of at least 4 mm2 maximum length of 12 meters (photo below).
Additional Information: When laying greater wiring length is increased to the desired cross section of 6 mm square.
To all this is added the following requirements:
- Connection device for kitchen use copper stranded wire to the ground bus;
- when three-phase supply number of wires is increased to 5 units;
- Line installation is required RCD.
Please noteThat in reality the power of 380 volts is possible only in private homes.
connection methods
Various electrical products of this class are connected as follows:
- The two-phase switching.
- Three-phase connection.
- Single-phase connection.
The first two options are relevant for private dwellings, and the third is used in city apartments. He considered as the main process.
Single-phase version
In this case the connection diagram has the form shown in the photo below.
In accordance with Figure terminals 1, 2 and 3 as well as the contacts 4 and 5 are connected to the copper section of the webs is not less than 6 mm2, which is normally present in the kit plate.
Connecting the lead wires is performed in the following sequence:
- First phase conductor brown connected to the joint terminals numbered 1, 2 and 3.
- Zero tire blue insulation is connected to the fourth or fifth contact.
- The grounding wire (insulation color - yellow-green) according to Scheme connected to second terminal.
Their terminals should be tightened up to the stop. When poor contact in the terminal of the working parts may burn, which is very dangerous for long term use of heating equipment.
The two-phase switch
This type of switching although rare, but still found in some embodiments, the connection of electric furnaces. Thus, in a private home, for example, only two of the three phases (A and C) may be used.
Note: In this case, terminals 1 and 2 are connected to copper crosspiece to which, in turn, connects the phase A.
Procedure rasklyucheniya other conductors does not essentially differ from the method described previously (pictured below).
three-phase connection
With three-phase power traditionally faced by the owners of country houses, which provides 4 or 5 cores in the power connector. Wherein the phase voltage is 220 volts, and the linear (between phases) - 380 volts.
In this case, the plate is connected according to the scheme in which all the connection terminals are used separately. The three phase conductors are switched to the contacts to the terminals 1, 2 and 3. Rasklyuchenie terminals 4, 5 and 6 is performed, like the single-phase embodiment (pictured below).
General recommendations
Before taking an independent connecting the AC power cable - it is desirable to read the following recommendations of experts:
- Before starting work, first of all, you should make sure there is no voltage in the network.
- If any - to turn off the circuit breaker in the electrical panel.
- The supply voltage to the unit should switch via a separate junction box.
In the case of implementation of these recommendations an independent plate connection does not cause any difficulties.
