Frequently Asked Questions (FAQs)

1. What is circuit breakers?

A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by overcurrent/overload or short circuit. Its basic function is to interrupt current flow after protective relays detect a fault.

2. What are the types of circuit breakers?

There are three basic circuit breaker varieties: standard breakers (which include both single-pole and double-pole circuit breakers), ground fault circuit interrupter circuit breakers (GFCIs) and arc fault circuit interrupter circuit breakers (AFCIs).

3. What is a circuit breaker and how does it work?

Circuit breakers are essentially resettable fuses that are automatically operated electrical switches that cut off the circuit whenever the current jumps above a safe level, avoiding overheating, melting, and potential fires.

4. How does a circuit breaker work GCSE?

Circuit breakers act as resettable fuses . These are automatically operated electrical switches that protect electrical circuits from overloading or short circuiting. They detect faults and then stop the flow of electricity.
