Westinghouse Circuit Breakers - You and your home are being silently protected from fire and injury by a very important device - the circuit breaker. Without breakers, the risk of damage would be great. You can perform some basic diagnostics if a breaker keeps tripping, but be very careful! You could easily injure or kill yourself if you contact a defective device or exposed wiring. Always hire a licensed electrician to make repairs or extensive troubleshooting.

Located inside your home is a circuit breaker box or panel that contains circuit breakers. Some homes have more than one panel. There may be a main panel plus one or more sub-panels in other locations.

There will usually be a large main breaker at the top of the panel with a high rating. The breakers for your branch circuits are physically smaller and have a lower amp rating. Be advised that shutting off the main breaker will also shutdown the branch circuits, but there is still high voltage in the breaker panel. The main wire leads into the panel are still active, and shutting off the main breaker will not stop current flow to these main leads.
