I'm looking at a job for a customer who wants a sub-panel with 22 GFCI circuits for his Christmas lighting. There would be (11) 4 square boxes, each with two GFCI receptacles. I was thinking of using a gutter with the 11 boxes mounted above the gutter. Do I need to run individual ground wires all the way back to the sub-panel due to the GFCI's or can I run a larger ground wire to the gutter and tap it at each box location to feed the GFCI receptacles?
I'm trying to reduce the number of wires in the HR feeds as much as I can because there won't be any shared neutrals and also the limits of Table 310.15(B)(2)(a). This will all be exposed conduit in his garage so I'm trying keep the number of conduits between the sub panel and the receptacles to a minimum.
FYI - Each quad will feed the (2) power cords of a 16 channel light controller with sensitive electronics inside. So, with that in mind also, I'm thinking it might be better to take grounds from each GFCI all the way to the ground bar in the panel.
