From out of NY. Roughing in outlets in a basement in NYC. Couple of questions:
1- Is MC 12/2 with a separate green ground ok? Or does it have to be AC 12/2 with cable as ground? (I was advised 12/2 AC with the AC as a ground is no longer acceptable and it must be MC with separate green wire)
2- On a 20A circuit is 10 outlets per circuit acceptable?
3- Roughing in a 10/3 30A line for an AC or heater. Can regular BX/AC box be used or does it have to be a larger square box with separate connectors.
