If your pool pump trips breaker immediately then your pump could be drawing more current than it has done in the past.
However, if you believe rain might be the cause then you might do this:
- The pump’s bearings or motor may have begun to rust causing the motor to strain
- The thermal overload protector or circuit breaker may be short circuiting because of corrosion or water.
- Debris or dirt from weather factors have worked its way into the pump’s impeller housing, causing the motor to overwork.

Pool Pump Trips Breaker Immediately After a Few Seconds
I had one that used to do this. The first thing to check is to make sure the wires attached to your breaker and are correctly connected.
To do this:
- Simply take the breaker out and turn the screws holding the wires as tight as you could.
- They many not be noticeably loose, but tighten them down some more. That provides more surface contact area for a better connection.
It’s been 4 years and this hasn’t tripped ever since.
If the past suggestions don’t work for you then you may need to test the power leads for shorts. Check for both grounding and cross-lead shorts. A wire rotting away to the point where resistance would go up after running for a bit and the breaker would throw.
If you have no idea how to do this, find somebody who does. 220 volts AC (or even 110 for that matter) is not something to be trifled with.
The new wire is going into 1″ PVC conduit, so it should last much longer this time. That reminds me, I should get the camera out.
That should fix the problem!
