Question

What is phase wire?What is the function of phase wire and neutral wire?

Answer 1

The HOT WIRE OR PHASE WIRE is basically a phase conductor which is connected to supply mains. ... The materials used for PHASE WIREis invariably ACSR( ALUMINIUM CONDUCTOR STEEL REINFORCED) OR COULD BE STRAIGHT OR STRANDED COPPER OR ALUMINIUM CONDUCTORS.

A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phasecircuit at the same line to ground voltage because it uses less conductormaterial to transmit a given amount of electrical power.

Neutral is a circuit conductor that normally carries current back to the source. ... In the electrical trade, the conductor of a 2-wire circuit connected to the supply neutral point and earth ground is referred to as the "neutral".
