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.
The main circuit breaker is a critical component of your home's electrical system, responsible for controlling the electricity flow and protecting the circuits from overloads or faults. Replacing it is necessary when it shows signs of wear or damage. 1.
If the new breaker does not remain closed and/or behaves similarly to the original breaker, shut off the power and contact a licensed, competent, and insured electrician. If you cannot find the main power cut off switch, do not attempt to remove a circuit breaker or work on the circuit panel. Contact an electrician.
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.
