Question
What happens if there is any insulation failure in electrical installation in a system?
- The current starts leaking out and an earth leakage circuit breaker helps to cut off power supply
- The energy starts leaking out and an earth leakage circuit breaker helps to cut off power supply
- The voltage starts leaking out and an earth leakage circuit breaker helps to cut off power supply
- The wire insulation starts leaking out and an earth leakage circuit breaker helps to cut off power supply
Hint:
- The current starts leaking out.
The correct answer is: The current starts leaking out and an earth leakage circuit breaker helps to cut off power supply
- The current starts leaking out and an earth leakage circuit breaker helps to cut off power supply when there is any insulation failure in electrical installation in a system.
