What is the grounding requirements for a jacuzzi installed in a single family dwelling? I was told that in addition to GFCI protection, the jacuzzi motor has to be grounded to a cold water pipe - true?
Jacuzzi is a brand name but I suspect you mean Spa or Hot tub. The bonding requirements for these are at Article 680.42(B) for outdoor installations and 680.43(D) for indoor installations. In either case, the pump will need to be bonded by means in part (E), and part (F) describes the grounding of this equipment.
