680.74 requires metal piping systems and grounded metal parts in contact with the circulating water to be bonded together. If there are no metal pipes, then no bonding is required. You are making an equipotential grid. Never is it required to bond a hydromassage bathtub to the panel or the service. NEVER!!!!!!

That said, it is still required to include an equipment grounding conductor with the branch circuit conductors feeding the motor, and that conductor is bonded inside the motor to any metal parts. But no additional bonding to the panel is required.

I worked for an electrician in NJ. The Inspector failed the rough in because he wanted a ground wire ran from the motor bond lug to the CB Panel due to plastic plumbing.This was in Salem county Nj

He had you do that because he doesn't know the difference between grounding, bonding, and equalpotential planes.
