120v Outlet/ 208v wiring

[Alwayslearningelec]

On a job that has a 120v receptacle being fed with 12/3 MC cable. they are using the white as a ground, labeled the red wire with white tape and using as neutral and the black is the phase conductor. Is this a code vialotion? Thanks

Yes a violation. Why wouldn't they use the white as the neutral and use the red as the EGC?

I don't. Is relabeling all that's required to bring it up to code? Hoping ot get some extra work out of this and not just relabeling. LOL

Look at 250.119(B).

Sounds like it may be AC

No grounding conductor, I would think it's pretty old.

I think the MGM hotel fire was caused by fault current being carried on the sheath of AC

It could be type AC cable. Maybe the white was grounded somewhere (like a screw through the cable) so they used it as the EGC.

AC is still made and is easily available. Until recently all HCFC was AC
