Connection scheme for a 380 volt outlet

3-phase sockets are used to power powerful electrical appliances and installations. In everyday life, they can be installed in order to connect a powerful welding machine, engine or machine in the garage or at the cottage. Of course, for such consumers it is necessary that the home power supply network be in 3 phases. Next, we will consider a typical connection scheme for a three-phase 32 A socket with grounding.

Each terminal has its own mark: L1, L2, L3 - phases, N - zero, PE - grounding. When you connect the wires, the main thing is not to interchange the contacts. Better before connecting, read again color coded wires. The connection diagram for an electric three-phase outlet at 380 Volts is as follows:
