Using RMC As A Ground.

CNC

When using RMC as a ground, is there a limit to the size of circuit you are using it for?

To continue a EGC through a pull box that has already had wires pulled through it, with RMC entering and exiting the box, can you ground it after the wires have been pulled (ground something that hasn't been grounded for years). grounding locknuts, or bonding bushings aren't possible with wire in the pipe. You can jump it out side the box can you?

No.

As long as the locknuts are made up tight, and it's a metallic enclosure, you're not required to use wedges, bond bushings, or anything of the sort. The bonding is already in tact.

No.
