    OK, I think I have it...

    The installer is drawing power from that form of 3 phase which uses the ground as a third leg (not sure if this is the wild leg format or not)...

    The real issue is the third leg (ground) is on the wrong terminal of the unit...

    Been a few years since I did any commercial, this stuff is getting fuzzy in the grey cells... do not do any 3 phase anymore.

    Waiting for the answer...

    Need to know if the green is from power or grounded.

    If it's grounded, then we are single phasing on one leg, unless a high leg is present controlling a circuit some controls are on.


    Never seen this or thought about it- I'm educationally guessing.

    10 ton 208/230 v 3 Phase Trane gas Pack. The Green wire is used as a HOT Leg of Power. And There is not a proper Ground to this unit. To top it off this is located on the "Former City Hall" Where the Inspectors office was at the time of install 10 years ago.

    Well the inspector must have been cold and said to go ahead and use green for a hot wire. If they would have put a ring of Black Tape on the green would that have helped make it legal?? HaHa

    Classic!

    Inspectors are NOT about safety, they are about an easy income... Actually, to a degree they seem to have an entitlement mentality (like everyone else on the govt dole... payroll or non-working).

    I'd guess that the red conductor failed some time back and some city repairman did away with the ground and repurposed the ground conductor rather than pulling in a new wire.

    I doubt any inspector was involved.
