does the grounding wire for hot tubs in residentinal, have to return back to the main dissconnet, or can it go to the sub panel first?
 
I don't have time to look it up right now, but I believe it HAS to go back to the sub panel. What comes to mind is the rule that all conductors of a circuit, including phase conductors, neutral, and EGC, must be in the same conduit.

Are you asking whether it has to be landed in the sub panel, or whether it can be allowed to be run separately and not go to the sub panel at all?
 
Only the grounding conductor of the feeder to the panel serving a branch circuit to an outdoor spa or hot tub is required to be run directly to the service equipment to comply with 680.25 of the NEC. If an indoor spa or hot tub, Part II of 680 does not apply.
 
Bryan, How would you run the Grounduing conductor "With the feeders" as required by 680.25 (B) if the feeders did not go to the Service Disconect???
 
The question really begs, is he asking about the equipment grounding conductor or the "equipotential bond conductor"?


Whenever someone asks me about the grounding of pools or spas (hottubs), I ask them which conductor they really mean. Most times the question is about the Equipontial bond conductor.

You can't. If the panelboard supplying the branch circuit to spa is existing, the feeder meets the exception of the section. In the event you install a new panelboard to supply a branch circuit to the spa, that panel must be connected to a feeder run to the service equipment and containing an insulated EGC.
