Question

Name the wire with (a). Red insulation cover (b). Black cover (c). Green cover.

Answer 1

1: Insulation:

The insulation of the wires in a three-core cable is given colors because each wire serves a specific function. It also helps to standardize the practice everywhere.

2: (a). The wire with the red insulation cover is the live wire.

(b). The wire with the black cover is the neutral wire.

(c). The wire with the green cover is the earth wire

Hence, the wire with red insulation cover is a live wire, the wire with black cover is the neutral wire, and, the wire with the green cover is the earth wire.
