Since the faceplate is screwed into the yoke, and the yoke is screwed into a nonmetallic box, the faceplate would not be grounded, which is a violation of 406.6(B).
Also,
406.3(E)(2) (2023) Installation in Nonmetallic Boxes.
Isolated ground receptacles installed in nonmetallic boxes shall be covered with a nonmetallic faceplate.
Exception: Where an isolated ground receptacle is installed in a nonmetallic box, a metal faceplate shall be permitted if the box contains a feature or accessory that permits the connection of the faceplate to the equipment grounding conductor.
I need to pull six 10AWG circuits from my panelboard up to a 24x24 in one pipe and all circuits require an iso ground. Does each circuit need its own dedicated iso or can I get away with pulling only one and splicing off it in that 24x24 and would I have to upsize it? Can’t seem to find it in the code
One plenty IGC its plenty for all circuits, make sure you don't bond anything else with them, use your conduit or tubing as the EGC and if you need flexibility downstream from the Jbox use hospital grade MC
