I'm remodeling the kitchen/bath wet wall, and I ran 3/4" emt over from the breaker box to a good sized box, to which I'm running 3 or maybe 4 flexible metal runs, like a spider.
What is the code for running the grounding conductor, do I have to pull a single ground wire all the way back to the panel box ground bar for each remote outlet?
Or can I run a single wire back to the junction box, spliced to a single (heavier?) ground wire running back to the panel box, similar to what I'd do if everything was on a single power wire?
Or can I just attach the ground wire to the metal junction boxes at either side of the flex run that I'm providing the grounding run for.
All metal is required by local code. TIA
