Grounded Copeland Hermetic New Install

[Royal241]

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.

So out of curiosity, did the new compressor have the same "overload" configuration as the dead one?

You are kidding me, I like that, Duhhh. Man that was funny, I'm licensed and now my ****. RST97C1E TA5. It came out of a RLH125M44E. I will get off my high horse and do what I do best without your answer. For one I will think I had a bad compressor and know that I did a proper install.

Royal:
What was the kidding post in relation to?
I don't think anyone is trying to grind your gears...the "you are joking statement by 2sac was directed at Slatts if that is what you are talking about.

[Slatts]

You are joking, right?

If you have only 1 phase hooked up to a 3 phase motor you'll have the same potential at all 3 terminals. nothing will happen till you connect another phase.

3 phases it will run, 2 phases it will cook and hopefully trip its safety, 1 phase it will do nothing.

[Royal241]

No man, Ryan thinks I had a single phase and connected it to a 3 phase, don't you see about the configuration? Slatts is a kool dude

[2sac]

Maybe the terminology is different between here and Australia. A single "leg" won't cause any harm. The second leg is the 208/230 "single phase" which will kill a 3 phase compressor.

Stop it royal, you've made me blush.

Here we switch all 3 phases.

If we loose 1 through a burnt contact, wire or fuse, the compressor is said to be 2 phasing.

occasionally I've seen 3 phase compressor where only 2 phases are switched, particularly in old York airconditioning condensing units.

We reticulate at 240Vto earth, 415V between phases at 50 Hz.

Dude, if you around Boston, I know some mean dudes I ride with and I mean Harley! Terminology doesn't change, leg or phase, same thing, we are all working on the the same thing, cooling our customers and being profitable doing so, tx guys.

[Slatts]

kind of counter intuitive, don't you think?
