If I install a lock-out device on a circuit breaker while it’s
in the ON position, will it still trip in the event of an overload?
Yes. The mechanism within a circuit breaker will still trip even if the handle is
locked in the ON position. The purpose of the lockout device is to prevent manual operation of the breaker only.
I have a Murray circuit breaker panel E-26095. I can’t locate the main switch to turn off the power so that
I can replace a 30 amp breaker. Any advice?
Some older breaker panels may not contain a main breaker; rather, there are up to
six breakers on the top part of the panel that together would turn off all power to your home.
Another possibility is
that you may have a main disconnect on the outside of your house near the meter. This type of setup would not require a main
breaker on the inside panel.
I have a problem with a 15 amp circuit breaker making crackling
noises and frequently tripping when I use my microwave. Can I replace this with a 20 amp breaker to get rid of the problem?
You should never replace a breaker with a higher rated one, as this can lead to
a fire. The crackling may be due to loose connections
in the panel. If it hasn't gone on for too long, you may be able to take care of the problem simply by tightening ALL wire
connections in the panel. If the problem is advanced, you may need to start replacing components. A visual inspection will
tell for sure.
