Hi everyone and thanks for all your help building my workshop.
Two of my circuits include wiring power strips in the circuit. I want to mount the power strips directly on the poured concrete foundation wall. All other cable on the vertical surfaces will be in EMT. The face of the powerstrip that will be flush to the wall will have stamped, ready to be removed knock-outs (that I’ll leave intact) and a couple other open spaces (e.g. multiple holes for ground screws).
I’m pretty sure I should be okay, but figured that I’d be better off double checking. Given the nature of the search terms I’ve been using, I keep coming up with useless results in Google. Can someone here help me out —it’s not a junction box per se, and isn’t expressly built for mounting directly on the concrete. On the other hand, it isn’t expressly built not to be mounted as such, and it’s basically a long metal rectangle that’s about as close to a junction box save the thickness of its walls.
I don’t think there should be any problem with mounting the power strips on the wall, but if you are hardwiring these into your panel, they need to be on a GFCI breaker since it’s in the basement.
Thanks. All the circuits have either GFI breakers or a GFI outlet first in line.
Most of the boxes I’ve used have a raised hole for the grounding screw. For the one or two that didn’t I marked it and drilled out a small void to make things easy.
The basement is (relatively) dry and it’s never flooded (even when the area has), but who knows what the next ten to twenty years will bring. How thick of a backing piece of wood would make a difference? I suck at using the conduit bender, especially for very subtle distances (much prefer the prefab offsets and the like).
