Was cold. I have never seen a compressor like that one, 3 ph with an external protector on one leg (same as in single phase ones). As I said, the protector never closed and I jumped it, well I got a grounded compressor, braker popped, then kicked compressor and there was no more ground to it, just one winding opened. Well, it's been one month now, the new compressor is doing just fine, got it under warranty, if cope and finds something wrong on my side, then I should hear from them...maybe. Thanks for suggestion, beer cooler for construction dudes, it might have happen. I didn't want to go back to the job site so that's why I shut it off the way I did, guess I learned something new by now...was cold out there that day...high roof, etc. Thank you guys for being thoughtful.
