Question
When does a circuit breaker trip?
- The circuit breaker trips when too much tensile force is applied across it.
- The circuit breaker trips when too much power is supplied through it.
- The circuit breaker trips when too much voltage is applied across it.
- The circuit breaker activates when a heavy current flows through it.
Hint:
A circuit breaker will usually trip when there is an electrical fault that could cause damage to the circuit.
The correct answer is: The circuit breaker activates when a heavy current flows through it.
A circuit breaker will usually trip when there is an electrical fault that could cause damage to the circuit. This is usually an excess of current, a power surge or a faulty component
The circuit breaker activates when a heavy current flows through it.
