I am new to the site. I have read several threads about tripped breakers but my problem seems a little different and I am looking to see if anyone else has had the same problem. When I turn my main pump on by hand or by timer, it comes on and runs for about 10 sec and then kicks 20A breaker off. I reset the breaker and it will run forever. It is just the initial start up. The pump is about a year and a half old. Please help.
