MC & Art 517

I think if you contact Southwire that the jacket (the aluninum skin is a little thinner than normal) is lightweight, and needs the full size ground to meet the UL standard. Next roll you break out, see if it has the manufacturers instructions and UL test number to verify that above information is correct.

You're welcome.

AFC Cable is a local manufacturer here in New England and most new non-residential buildings here are wired entirely with MC cable, particularly the blue MC Tuff. I'd be surprised if you had AFC products on the west coast.

Yes, the coiled nature of MC sheathing creates a large impedance should it be required to carry a fault current. It is my understanding that in MC AP the bare aluminum wire is placed in contact with the sheathing to eliminate this problem just as the bonding wire did on the old armored cable, also known as BX.
