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.

Everything you need to know about the point of entry for a home's electricity, from an electric panel breakdown to how to hook solar panels into your home's power system.

A GFI receptacle contains its own breaker system (two plugs with two buttons in the center). One button tests the circuit and the other resets it.

However, one often-overlooked category is protection of circuits and systems provided by the power supply and accompanying circuit breakers.
