Question about A O Smith Motors A O Smith 1hp 115/230v Ur Square Flange Motor - Usq1102
USQ1102 pump gets power, buzzes for 10 seconds and then trips breaker. Connections look ok, minor corrosion, I am curious about the start capacitor & what looks like a safety switch attached to it. Any ideas?
The motor-start capacitor is bad. This is a very common problem. It can be easily and cheaply fixed by replacing the capacitor. Replacements are usually less than $10.
See http://www.youtube.com/watch?v=ZEIv5ClLqXg for a step=by=step guide.
When you have the capacitor in hand, check the model# which is printed on it. Alternatively, you can Google the motor brand & model to find the parts list which will identify the right one. Then Google the part number, to find a seller.

I had the same symptoms: pump runs, buzzes loudly, trips breaker. I puzzled over it for some time. The other respondents are correct: it probably is the capacitor. In my case it wasn't. Turns out that I had moved the motor and somehow the 115/230 Volt switch got set to 115V even though I was connecting to 230V. Before screwing around with the capacitor, first check to see if the internal switch is set to the correct voltage- that is, the voltage you are sending to the motor. It takes about 5 seconds.
