So I have 3 total panels in my laundry/utility room. Panel "A" is the Main Panel (150 amp), Panel B is the 100 amp sub panel directly to the left of the main panel, connected directly to the main panel with a 2 1/2" short nipple and #2 wire. Panel C is a 100 amp sub panel sub metered (meter in-line with the power feed to Panel C) this panel is fed from the main panel (A) with a 60 amp breaker and #2 wire as well (future ability to upgrade to 100 amp to panel C).
In short, 2 sub panels B, and C are directly connected to the main panel via thier own conduits.
What I'd like to do, I have an outdoor outlet out front physically connected into panel B, but need to electrically connect it into Panel C for the KWH monitoring just for my Holiday Lights. This would be a temporary thing (seasonal) and the rest of the year it would be on its own breaker in Panel B. I was thinking of connecting Panel B and C together with a length of 3/4" conduit to pass the wires between the two panels just for this one circuit (effectively creating a conduit loop between all 3 panels).
I know that if this is acceptable that the neutral and the hot for this circuit must be connected in the panel that serves it (so I will pass both a neutral and the hot through the 3/4" interconnecting conduit) but does the ground need to be connected to the same panel or can it stay connected in Panel B? Panel B and C connect to the main panel via PVC conduit, but have 4 wires (HHNG) and no the neutral bar is NOT bonded to the panel.
My initial thought is yes this is ok, but I figured i'd check here to see what others had to say about this.
