Learning how to replace an electrical circuit breaker is not all that difficult. You can also easily replace the circuit breaker within one hour. You will need a few common tools, usually already found in most households. To start with, you need to identify the bad circuit breaker. After you've identified the bad breaker you need to switch off all electricity to the electrical panel. Once you've done that, you can proceed to replace the circuit breaker. You'll first need to remove the front panel off of the electrical breaker box. The panels are usually held on by screws or small bolts. Remove these and then remove the front panel. You now have access to the wires that are connected to the circuit breakers. Locate the circuit breaker that you are removing and loosen the screw over the white wire just until you can pull the wire free. Push the white wire out of the way. Remove the other wire on the circuit breaker, usually black in color, the same way and push it back out of the way. Grab the circuit breaker and pull it out. Replace firmly with the new circuit breaker. Reattach the wires in the reverse order that they were removed. Remember to tighten the screws firmly over the wires inserted into the circuit breaker. Repeated hot and cold cycles of current can loosen wires that are not tight enough and cause a serious hazard. Replace the front panel of the circuit breaker box. Turn the electricity back on to the panel. Make sure the new circuit breaker is flipped to the on position. That's all there is to replace a circuit breaker.
