Circuit Breakers Help Keep Your House Safe
Electrical circuit breakers play a critical role in keeping your home safe by interrupting the flow of electricity when overloads, shorts, or faults occur. At Lowe's, we carry trusted brands like Eaton and Cutler-Hammer, making it easy to find reliable protection for your electrical systems.
When Circuit Breakers Trip
It's common for a breaker to trip when multiple high-wattage appliances are used on the same circuit. If this happens frequently, consult a licensed electrician. You may need to redistribute your appliances across different circuits or install a new one. Persistent tripping could also mean the breaker itself needs replacing. Keep in mind that replacing a breaker may require a permit and must meet local electrical codes—inspections are often necessary, even for experienced DIYers.
Types of Circuit Breakers
Most residential circuits use 20-amp single-pole breakers, which protect individual wires and commonly trip during shorts or overloads. These are the standard breakers for general home circuits. For larger appliances, like refrigerators, washers and dryers, or HVAC systems, you'll need double-pole breakers, which control two wires and offer higher current capacity. These are easily identified in your breaker box by their side-by-side, interconnected switches.
GFCI and AFCI Protection
In moisture-prone areas like bathrooms, kitchens, or outdoor spaces, opt for GFCI (ground-fault circuit interrupters). These breakers prevent electrical shocks caused by ground faults. We carry GFCI breakers in a variety of amperages, from 20-amp to 50-amp, especially within the Eaton line. For enhanced protection, consider AFCI (arc-fault circuit interrupters), which detect potentially hazardous electrical arcs that could lead to fires. These specialized breakers are often required by code in living areas and bedrooms.
