Question

Write down the working and colours of the insulation of the wires used in the domestic electrical distribution circuit:
(i) Live wire
(ii) Earthing wire
(iii) Neutral wire

Hint:

The earthing wire is crucial for preventing electric shocks by directing excess current safely into the ground.

Answer 1

The domestic electrical distribution circuit consists of three main types of wires:
- Live Wire: This wire carries the current from the supply to the electrical appliance. It is typically red or brown in color.
- Neutral Wire: It completes the circuit by carrying the current back to the power source. It is usually black or blue in color.
- Earthing Wire: This wire provides safety by preventing electric shocks. It carries leakage current to the ground and is generally green or yellow-green in color.
