Is it OK to drive a ground rod at a machine if switch gear & buss plug have no ground
Were in an older plant built in the 50's. The Switch Gear, Buss rail & Buss plugs are 3 wire 3 phase 208 V with no ground. There using the conduit & frame of the buss rail, buss plug and switch gear as ground. Question is it legal/safe to drive a ground rod at each machine to ground the machine since? Will this create a ground fault condition or other problems?
