To change a circuit breaker, find the main circuit breaker box and locate the defective breaker by looking for a tripped breaker. Next, turn off the branch breaker boxes, the main power, and the individual breakers. Remove the screws holding the circuit panel's face plate, then loosen the screws holding the wires on the defective breaker.
Disconnect the wire on the circuit breaker. The wire connected to the circuit breaker will be held in by a flathead screw on one side. Use a flat-head screwdriver to loosen this screw slightly, without unscrewing and removing it completely. Separate the wire from the circuit breaker once the screw is loose enough.
Remove the screws holding the circuit panel's face plate, then loosen the screws holding the wires on the defective breaker. Then, remove the old breaker and replace it with a new one with the same amperage. Replace the wires, tighten the screws, and screw the panel's face plate back into place.
DO NOT attempt to replace the main breaker yourself. Call a licensed, competent, and insured electrician to handle this situation. DO NOT attempt to access the meter box, underground wiring/overhead cable, or any equipment owned and/or maintained by your power company. Call your power company if any of their equipment needs service.
