I'm working on installing the electrical service for my new hot tub, and I have a question on running the electrical connection.
According to the National Electrical Code (NEC), it states in section 680.25 (B) that:
"An equipment grounding conductor shall be installed with the feeder conductors between the grounding terminal of the pool equipment panelboard and the grounding terminal of the applicable service equipment or source of a separately derived system. For other than (1) existing feeders covered in 680.25(A), Exception or (2) feeders to separate building that do not utilize an insulated equipment grounding conductor in accordance with 680.25(B)(2), this equipment grounding conductor shall be insulated."
... "These provisions shall apply to any feeder on the supply side on panelboards supplying branch circuits for pool equipment covered in Part II of this article and on the load side of the service equipment or the source of a separately derived system."
OK so last weekend, I ran 120 ft of 4-3 (inside the house) without an insulated ground, now what do I do?
Do I have to run new wire?
Can I put in a junction box and switch to the an insulated ground wire before exiting the house to connect to the GFI Junction Box?
Thanks,
Bill
