We already know the difference between single phase and three phase power supply as well as balanced and unbalanced loads system, so we will never repeat them again. This way, a three phase distribution can also provide single phase supply from any phase and neutral. In UK, EU and other countries following the IEC rules, the voltage between three phases (L1, L2, and 元) are 400V, Three Phase (4 or 5 Wires) while the voltage between any Phase and Neutral is 230V AC (2 and mostly three Wires including the protective earth “E”). used to control and safely distribute the power supply to the electric appliances and devices.Ī distribution board is also known as main breaker box, electric panel or panel board used in commercial (as industrial) and domestic (as residential) applications to fulfill the need of safe electrical installations and distribution.
