MC Cable

[j rae]

If you can get MC cable with an insilated ground whats the difference between regular MC vs. Hospital grade??

Whether or not the outer sheathing of mc cable is listed & identified as an equipment grounding conductor. 250.118

Hospital circuits require a ground path and a shell bonded path that are isolated from one another. MC by default does not provide a ground path in the shell by default.

Is a MCcable anything like a MCmuffin?:grin:

There is a newer type of MC cable called MC AP that is a cross between AC and MC. It saves 30% on installation as there is no EGC to make up.

Regular mc lacks a redundant ground

Hospital Grade "MC" is actually Type AC cable, since as the others have mentioned, the armor of MC cable is not listed for grounding.
