In this video, we learn how to change a circuit breaker. First, turn the main breaker off so there is no running electricity. Then, go to the meter area around your circuit breaker system. With these, there will be wires running all around the entire system. With most breakers, you can pull them right out from where they clip in. There will be a wire connected to this which you can remove. Do this, and then connect the wire to the new breaker. Snap this back into place and make sure it's secure in place. Then, turn the power back on and your breaker will be changed.
