Hello, wondering if anyone can help me out?
I'm working on a restaurant build-out and there are two existing sets of 3" conduits already installed underground and stubbed into the tenant space. The stubs are steel, but I?m wondering if the conduit under the slab is PVC or steel? Because I want to use the conduit as my ground, but might get screwed if they installed PVC underground and I show no ground wire....
I have an 800 Amp service. Worst case scenario, I?m trying to feed 2 sets of 4#500 and 1#1/0G into two existing 3" conduits. Will this work?
