I'm installing two new outlets in two metal junction boxes in a metal enclosure that houses a bunch of networking gear.
Each outlet is GFCI and supports two whites (neutrals), two blacks (live), & a green screw for the ground. I know I only need one technically but I can't return one of them.
Each junction box has two green screws for a ground wire and the metal enclosure has a screw for a ground wire.
The 14-2 cable in image is not GFCI protected upstream. (electrical panel -> a non GFCI outlet -> 14-2 cable in image). I know that having two GFCIs is overkill but I already bought them & can't return one.
Can I connect the line 14-2 cable's black & white wires directly to GFCI outlet 2 in junction box B without using a pig tail? I think I can do it for the black but I believe (but am not sure) it might not be the best idea for the neutral because I'm using GFCIs.
Do I need to ground both junction boxes and the patch panel's ground? I think the answer is I should but what's the best way to do that? Should I use a grounding wire connector nut in each junction box to ground the outlet and the junction box & have one run outside of the junction box for the metal enclosure?
