Electrical power supply for homes

20 Jul

Electrical power is supplied to our homes through the main supply cables from nearby substation. There are two types of current : direct current and alternating current. The type of current supplied to our home is alternating current with a voltage of 240 V.
.

Every house has an electrical wiring system that suplies electrical power to all electrical appliances in the house. There are two types of wiring systems; single-phase wiring system and three-phase wiring system. Single-phase wiring system is usually used in our homes because most consumers in residential areas only need a low voltage, for example, 240 V. The three-phase wiring system is usually used in commercial and industrial areas where there is a need for high voltage, for example, 450 V.
