Miniature circuit breaker FAQ
Q: What is an AC circuit breaker?
A: Circuit breaker is a mechanical switch that can handle current flow in normal conditions and can also interrupt current during abnormal conditions such as short-circuits. It is designed to make, carry, and break currents in the regular state and can also carry and break currents for a designated time under abnormal conditions.
Q: Can I replace a circuit breaker myself?
A: Testing and replacing a circuit breaker may seem straightforward, but it is important to approach this task with carefulness and extreme caution, even if you have prior experience working with electricity. Always assume that wires carry electrical current and are live. Under no circumstance should you attempt to work in a circuit panel that is live - ensure that you have turned off the main circuit that supplies power to the panel box.
