The electrical panel (a.k.a. circuit breaker box, or “fuse” box) is the central switching station of the electricity in your house. All the electrical current coming from the municipal grid enters the panel, where it divides into the different circuits for the outlets and fixtures in the house. To protect the electrical system in case of shorts and other problems, breakers are designed to trip and stop the current to a circuit.
It’s easy to take the electrical panel in a house for granted. You know where it is (we hope, if not go find out now) and you may occasionally need to reset a breaker if there’s a short in the house. A few tripped circuit breakers through the years is no big deal. In fact, it shows the panel is doing what it’s supposed to do.
