Circuit Breakers Help Keep Your House Safe


Electrical circuit breakers help to keep your home safe from electrical fires by stopping the flow of electricity, should something go wrong. Sometimes, using several appliances on the same electrical circuit at the same time can trip the circuit breaker. If this happens regularly, contact an electrician. The breaker may need to be replaced, you may need to put the appliances on a different circuit, or the electrician may need to install a new circuit.  


Replacing an electrical circuit breaker may require a permit, and strict electrical codes must be followed to ensure safe installation. Even if you’re qualified and comfortable with replacing a breaker yourself, you’ll need to have your work inspected. Most single-family homes use 20-amp circuit breakers that’ll trip in cases of electrical shorts or overloads. These are single-pole breakers that control a single wire. 


Double-pole breakers are easy to spot in your breaker box because they feature side-by-side, interlinked switches. These breakers can control two wires simultaneously. They’re necessary for appliances like washers and dryers that require large amounts of electricity. For more information, see our guide called Circuit Breaker 101.


At Lowe’s, we offer circuit breakers from top brands, such as Eaton circuit breakers and Cutler-Hammer circuit breakers. You can also find other types of circuit protection devices. Look for specialized products, such as arc-fault circuit interrupters (AFCIs). Sometimes called arc-fault circuit breakers, AFCIs detect unexpected electrical discharges or arcs that could cause fires.   


For damp or wet locations — such as kitchens, baths and outdoor locations — you’ll need ground-fault circuit interrupters (GFCIs) that protect you from electrical grounding faults.
