Grounding Bar vs. Neutral Bar?
Hello all. I have extended the wires from an unused 240 outlet to the backyard for a spa via a sub-panel. I also hooked up a new grounding electrode near it to avoid having to run a fourth wire all the way back to the main panel. This fourth wire goes to the small grounding bar in the sub-panel and from there to the spa.
The 50 amp circuit trips instantly when I turn it on. Is this because the wire that was originally used for grounding in the outlet is still connected to the grounding bar? Should I disconnect it from there and move it to the neutral bar? Some of these bars have jumpers so what difference would it make anyway? Help...
