Hey, question for the group on grounding when using MC cable and metal boxes....
Situation: Enclosed a carport and turned it into a garage. I'm branching off of an existing bedroom outlet circuit to add 1 outlet and 7 LED light fixtures in the garage area (1 exterior, 6 interior LED puck lights. I would like to do this in a way that is code compliant. The garage conversion was permitted, and I'm probably going to apply/pull the electrical permit just so I don't run into issues down the line. I just installed the 1st box (GFCI outlet) and everything else will be branched off from there this weekend. In that box, I created a pigtail for the ground, grounding the box and the GFCI outlet with their own connections (seemed redundant, but eh).
My question is: How does grounding need to be handled for the rest of the circuit (in a way that will pass inspection)? The way I see it, I would think that using MC cable and metal junctions, the rest of the circuit's boxes would already be grounded due to the metal MC cable conduit being clamped to each of the metal boxes (connected to the already installed/grounded box).
Do I need to create a pigtail for the ground in each of the remaining boxes and connect the green MC wire to both the box ground screw and the fixture (and the remaining circuit/run)? Or, can I just ignore the green wire and ground everything to the green screw in the metal boxes for the rest of the circuit?
