Okay gang- I was baiting you as is the habit with me.
Reno has covered part of it in that the plate would not be grounded and even if one were to use a non-metallic plate and nylon screws the yoke would not be grounded. There is an exception for a work around it in 406.2(D) so that's covered but the contractor would not be permitted to use the uninsulated conductor of the 12/2 w ground on the "Isolated Ground" terminal per 250.146(D)
What really gripes me tho is that the contractor had sold him a bill of goods on how much better system this was and I couldn't say anything to anyone but the contractor about his unprofessional deed.
