Isolation Panels

[brother]

I know that isolation panels are an ungrounded system. Also the NEC 2005 says that the 'orange' wire goes where normally the 'grounded conductor' would go on a receptacle.

Ive seen where some guys did NOT do this. Wouldnt the polarity of this cause a problem. I was told in reality it wouldnt make a difference on an ungrounded system. i dont think thats right. Help me with my understanding.

Brother, what code section are you looking at in the 2005?

I assume we are looking at 517.160.

i think you should read 250.146(d)

Im not talking about isolated grounding receptacles. This is dealing with 517.160 A (5)

basically im asking if there was 'reverse polarity' would it do any harm to the equipmment that is plug into it even though this is NOT a grounded system. We know that it would be against code to do it, but would NOT there be a problem here? remember im not talking about isolated grounding receptacles.

I don't see how the equipment would even know that the wires were reverese...there is no reference to anything else.

I agree, it won't be a problem. I think this paragraph has more to do with identification and being consistent.

I would hate to see the hot sides of some receptacles wired to the "normally grounded" sides of other receptacles. But in theory, this would work.
