Renron Posted December 16, 2004 Report Share Posted December 16, 2004 Here is a photo of a disconnect block in the attic of a home, it services a heat pump unit. My question is, can that small ground wire serve as the return leg safely if there is a problem with the other legs? Even if the neutral is not used by the unit should it not be available? Thanks for the help guys, I try to learn and listen from more experienced 'spectors.

Brian G Posted December 16, 2004 Report Share Posted December 16, 2004 Uh Mike, "Yep" to what? Other than the white hot leg I can't see any issue there. The grounds are bonded to the enclosure just like they are on any disconnect or piece of equipment. There is no neutral on 220v. They pulled a 3w / with ground on one side and capped the unused leg. I see nothing wrong there. Is I blind? [8D] Brian G. Quote Link to comment Share on other sites More sharing options...
Chad Fabry Posted December 16, 2004 Report Share Posted December 16, 2004 Looks good to me too. I'd recommend those cartridge fuses be upgraded to the solid copper tubing style that is so prevalent in my area. Quote Link to comment Share on other sites More sharing options...
Brian G Posted December 16, 2004 Report Share Posted December 16, 2004 Originally posted by hausdok I responded, "Yep," meaning I didn't see an issue. Ah-so, gotcha. That has to be record for you Mike. Only one word, containing only 3 letters. And they said it could never happen... [] Brian G. Quote Link to comment Share on other sites More sharing options...

Bruce Thomas Posted December 17, 2004 Report Share Posted December 17, 2004 Hey guys, Doesn't the ground have to be equal to one of the legs? Bruce Quote Link to comment Share on other sites More sharing options...
Brian G Posted December 18, 2004 Report Share Posted December 18, 2004 Originally posted by Bruce Thomas Doesn't the ground have to be equal to one of the legs? No, it's just an equipment ground. If that were the case there would be no such thing as "something / 2 with ground NM cable", it'd all be "something 3 plain". It isn't intended to carry any current. Brian G.

Renron Posted December 18, 2004 Author Report Share Posted December 18, 2004 Bruce, That was my thought as well, kinda "just in case" thing. I was wronge. Ron Quote Link to comment Share on other sites More sharing options...
