Electrical Question
I am rewiring my small room directly to a pge meter (legally). With fans, 2 1000w lights, and a dehuy I figure 32 +/- amps total draw max. Right now there is a sub panel connected to the mail house panel. That will be changed out to become a separate main panel powered directly to its own meter.
Here's the first problem, the underground power line I want to use contains only 3 wires. A black hot, a white hot and covered ground. It ran a 240v submersable. That will be disconnected.
I understand I need 3 wires and a ground; two hots and a neutral plus ground from the meter to the grow room panel. I could replace the 2+ wire with the correct 3 + ground but; second problem. About 10' feet of that 2+ground wire with out a neutral is 2 feet under a rock hard paved road. Don't particularly want to dig it up.
I could reconnect the covered ground making a neutral leaving me with no ground going all the way back to the meter panel.
Is there a way to ground at the grow room panel to substitute for no ground on the incoming cable that goes to the meter?
Hope this clear enough to make sense.
