Hello thank you for taking the time to look/answer my question. That being said my problem is with a ac motor for a air compressor it worked fine then all of a sudden it started to throw the breaker. It will start and run fine for about 5-7 seconds then it will flip the breaker. Any advise will be appreciated.
Here are some specs for the motor
a.o.smith
115v
15a
3450rpm
Model#d24228
Ph 1
I believe it to be single phase but not sure it does have two capacitors
Thank you

You may want to swap the wire to another breaker of the same size to determine if the breaker is OK.
Check the breaker for a loose wire connection and be sure the tab the breaker plugs onto is clean. Check the underneath of the breaker where the jaws plug onto the tab in the panel. Any looseness or corrosion will create heat that can trip the breaker.

I have tried it in many outlets around the house and it seems to always do the same thing
I even tried it at my friends house
Thank you for your time

OK then the motor is getting hot or overloading for some reason. Need to have it checked out. Check that rotation is proper. If you have an amp-probe, you can check the starting and running amps. This is similar to having your blood pressure check, without measuring the amps, everything is nothing but a guess.

HA I just found out from my friend that I let borrow it that he left it outside in a storm and it got soaked so that probably means its gone
That's the last time I loan out tools!

Well there you go, too bad he did not mention it when he returned it.
