Question

The color coding of earth, live and neutral wire respectively is:

✓

Answer

Green, Red, black.

Explanation:
The electric power line enters our house through three wires- namely the live wire, the neutral wire and the earth wire. To avoid confusion we follow a colour code for insulating these wires. The red wire is the live wire, and the black wire is neutral. The earth wire is given green plastic insulation. The colour coding of wires is green for earth red for live and black for neutral.
