If it worked before but is not working now you have another problem. If you have added something that is causing the overload then you need to address that. It is possible the breaker has gotten weak if it has tripped a lot and a replacement with another 15a breaker could solve the issue.


It did work before, but it would trip often. We’d just go and reset it and it’d be good for a week or two. Now it trips after 15 minutes.

We did add a water pump to the circuit, but that’s all that’s new and it’s hardly ever on. We did add about 8 more plug ins to the whole circuit, but nothing is plugged into them.

I don’t know what gauge the wire is.

Probably #14.

You can open the main panel and look at the conductor wired into the breaker. It should have the size stamped on the insulation.

ETA: if the main insulation is has been removed, you may be able to tell by the insulation color. Yellow normally means #12, and white is #14.

My panel has some 14s in it and the outer insulation is white. All the #12s are yellow.

Sounds to me that the circuit is overloaded. Normally, youd put 8 receptacles on a 20A circuit. You have a couple motors on that circuit as well.

It could be a number of things, but id run another circuit out there at a minimum.

The frequent tripping may have indeed weakened the breaker and a new 15a might get you back to where you were but unlikely to stop the problem. There is a decent chance it is the motor in your pump cycling and the inrush current is tripping the breaker that already has a load on it. It may be time to run a dedicated circuit for the highest load which is likely the pump motor.

If I had to bet I would guess your pump motor load runs afoul of NEC 220.14(C) calculations.
