Husky Air Compressor Tripping the GFI

[cmailliard]

I have a Husky Air Compressor (2.75hp and 8gal) that just started tripping the GFI in the garage when I turn it on. I heard somewhere about the circuit no opening all the way or something to that effect. I am dumber than dumb when it comes to electricity and motors. Any ideas?

In my experience, GFI outlets seem to be very sensitive. Also, you may be drawing too much current from that breaker, causing it to trip.

That is a pretty small compressor to be tripping your GFI. Could be your motor going bad or a bad GFI. Is it an old compressor? Cheapest bet is to go to home depot and get a new GFI.

Motors like vacuum and compressors trip some outlets. If it was known good until recently then its the gfci they get weak after a while.

The garage attached to house or detached, insulated? Colder temps put more of a load on compressors, especially if you have not drained them in a while.

I have tried it on different GFI's on different breakers, I tried it on a normal outlet and it worked fine. It is an older compressor, 9-10 years. Thanks guys.

Attached garage, it actually started when I went to blow out my sprinklers (actually on time this year). I will try draining it just in case.

If it does ok on other GFI's then you have your answer.

What is the breaker rating on the GFCI circuits ? 2.75 HP 120V single phase is pulling a little over 17 amps not counting start up current. Also when was the last time you checked/changed the oil in the compressor and lubricated the bearing of the motor ?
Also Ckeck/tighten the electrical connections in the motor for the compressor, unplug it first of course.

I had this happen with my compressor out of the blue a while back and the wire from the capacitor that aides in starting the motor was broken. Ie: it was drawing too much current on start up. Might be worth checking.
