Circuit Breaker Tripping


I have a circuit that has been working fine for a number of years that just started tripping. It won't stay on for more than a couple a seconds. It hums and trips as soon as you reset it. I tried replacing the actual circuit breaker but it didn't help.

The load on the circuit hasn't changed. It's just a couple of lights and outlets at the top the stairs in the hall.

You have short!

If nothing has changed on the load, start looking for rodent damage.

What jbfan said and it could also be a bad breaker but i would go looking for a short first. If you have a multimeter you could check continuity between the black and ground and between black and white, if you have continuity you have a problem. If you do this make sure you don't do it with the power on.

First remove all lamps and if any, disconnect ballasts as you will read continuity through them. Possibly a bad socket.

I agree with the above.

When I started stripped the laundryroom for it's reno into a diningroom I found that a continually problematic plug had an exposed wire - so using that plug led to the occasional toss of the breaker.

I fix it - done - no problems.

Yes you surely have a short circuit there somewhere.
Do you know all of the things on this circuit ?
Remove them one by one and try to re energise,
You will soon find the offending item,
If it is all removed, and you are 100% sure there is no more loads,
Then the fault lies in the wiring.
Just disturbing old wiring can cause problems.

Time to call an electricain.

I have a high hat ceiling light I hooked up to a switch and then to a 20 amp breaker with 14 gauge wire. The circuit trips right away and won't stay ON. Do I have to use a 15 AMP?
Pls advise
thanks

The wire is brand new and I used a 20 amp breaker that was working for a small hard wired heater. It worked fine for the heater. I took off the heater wiring from the breaker but trips for the new light.

You should have started a new thread.

Many heater as 240 volts. Did you check the voltage before you connected the light?

You cannot use the 14 gauge wire on a 20 amp circuit. You have created a fire hazard.
