Why does one switch on my circuit breaker trip once a week or so?

Question

It happens while I am at work. My dining room, overhead kitchen light, and microwave are on the circuit. The only thing on when this happens is the clock on the microwave.

Answer 1

best get an electrician in to check it out.

Answer 2

If your sure these are the ONLY things plugged into the circuit. I suggest unplugging the microwave while your gone. See if this solves the problem. That is only appliance capable of drawing a large enough surge to trip the breaker. It may have an internal problem. Elsewise it sounds like a worn breaker.

Answer 3

A bad breaker is a good answer. If your micro is not running, it cannot be pulling enough amps to break the circuit.
I would first question if you have everything figured out for this circuit. If you do then check the receptacles for loose or damaged wiring. that alone can cause your problem because the connection starts to arc. This is dangerous because you could have a fire. If any plugs are cracked replace them, they are cheap. If you do not resolve this you should try to get a knowledgable person there SOON.

Answer 4

Bad or weak breaker, from what you are saying there's WAY to much on that circuit, you need to have your microwave put on a single circuit by itself

Answer 5

Happened to me when I turned on the dishwasher. My electrician friend re-routed a spare breaker and hooked it up to that one. There are usually spare (unused) breakers available in the breaker box. Problem solved. Have this done professionally! Good luck...

Answer 6

The breaker is old and bad it needs replacing. But Its best to get a Pro to look at it...

Answer 7

Probably using too many plugs at one time or turning too many things on in the house. This happens in my house. You can call the electrician and he will probably charge you over $150.00+. My house has not burned down yet!
