Pump: Jacuzzi Cygnet 2
Motor: A.O. Smith 1hp wired for 230v production date in 2008 bearings replaced in July of last summer.
I had experienced a tripped breaker a couple times at the end of last season (September) so I figured I'd start early this year to get my issue resolved. I moved into the house a year ago so I have made no changes to anything.
My breaker trips at the main panel, not the sub panel. Only the pump and my light are on this circuit and the trip happens with the light off as well. The breaker trips randomly but it wont run any more than about 2-3 hours. So I started my diagnosis and I'll let you know what the results were.
Power on, Motor running = Tripped breaker at main panel
Power on, Motor non running = Tripped breaker at main panel
Power off at sub panel, but on at the main panel = No tripped breaker
So at this point it was pointing to the motor so what I did was totally un wire the motor from the sub panel and here is my result:
Power on, Motor disconnected and pool light on = No tripped breaker after 3 days
I think its pretty clear my problem is in the motor somewhere but I just want to be sure before I replace it entirely. I think its very odd that the breaker still trips with the motor connected but is off.
I wanted to get some insight on this and any help or recommended "tests" would be very helpful. Thanks in advance!
