220V Heat pump no neutral?


Recommended Posts

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.

( I know wrong color hot leg going to unit(white))

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]

Thanks guys!

I wanted to be sure of what I think I know....HuH? Yhaaa. I thought the white conductor was the wrong color too Brian.

:) see I'm learning...

About those solid copper fuses......:)

Mike. A one work answer. Is that a first?

Everyone enjoys our humor...It's nice to be back

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.
