As discussed in Part 1, the interrupting ratings of low-voltage circuit breakers and fuses are classified on a symmetrical-current-rated basis. In this context, “symmetrical-current-rated” implies ...

However, selective coordination of circuit breakers is a possibility. In fact, in many cases, breakers that do not appear to selectively coordinate (based solely upon their individual curves) do ...

The circuit breaker is one of the most important but least understood parts of your home electrical system, keeping you safe from electrical fires. Appliance Science looks at how they work.
