Explain the terms domestic and industrial wiring.

Here are three types of tests performed after electrical installation:

1. Continuity of Protective Conductors: This test ensures that all protective conductors (earth wires) and equipotential bonding conductors are correctly connected and have a sufficiently low resistance to effectively carry fault currents to earth.
2. Insulation Resistance Test: This test measures the resistance of the insulation between live conductors (phase and neutral) and between live conductors and the earth conductor. It verifies that the insulation is intact and prevents leakage currents or short circuits.
3. Earth Fault Loop Impedance Test: This test measures the impedance of the earth fault loop, which is the path a fault current would take from the phase conductor, through the fault, back to the supply transformer. It ensures that in the event of an earth fault, enough current will flow to trip the protective device (e.g., circuit breaker or fuse) within the required time to ensure safety.
