We have two conduits running parallel to a distribution board to create 400 amps. They are two 2" EMT with 4 4/0 cables each. We are running 1 additional conduit with the same cables to the same switch board to create 600 amps. The existing conduits are being used as the ground. Can we do the same with the new conduit, and where can I find this in the code book?
