The previous (original) owner of my house never labeled the circuit breakers
in the breaker panel. Every time I go to change a light fixture or a
receptacle, I have to go thru this trial/error process to find the breaker
to shut off. Now that I'm selling the house, I'd like to have all the
breakers labeled so the new owner won't have the same problems. Is there a
better way to figure out what breaker serves what outlet/light/fixture/etc
other than just flipping each breaker, one-at-a-time until the right circuit
goes dead?
