Is there a circuit breaker in your home that keeps tripping? It may need to be replaced. Fortunately, testing and replacing a breaker is something you can do.

The cloud-connected Leviton Load Center features intelligent circuit breakers that you can control or monitor from your phone.

Most people understand, too, that the breaker will trip if you overload the circuit with too many things plugged in or with an accidental short circuit. But how does this common device actually work?

Most places you live in today will manage their electrical power via circuit breakers, though fuse boxes predated that technology in the early 20th century.
