    Poll for Inspectors

    Section 680.74, 2005 NEC.
    Here's the situation.... Jetted whirlpool tub, residential wood frame construction, PEX (plastic) water line from a manifold in basement near the incoming 3/4" copper water main from the street. do you require..........
    a) a # 8 copper bond wire from the metal motor frame to the hot/cold faucet assemblies on the tub
    or...........
    b) a # 8 copper bond wire run to the incoming water main approx 100' away from the tub
    or..........
    c) some other option that I have not listed

    I know how I would (and have) done this, how would this be enforced in your areas?
    Thanks,
    Jim

    I wouldn't require anything...there is not a metal water piping system.

      If it's all plastic pipe I wouldn't worry about it, that is if we're talking about a bathtub type whirlpool.

      Mine is fiberglass, all of the piping is plastic and the motor is the plastic case type that doesn't require bonding and the water pipe is already bonded.
      I can build anything you want if you draw a picture of it on the back of a big enough check.

        c) Other option

        My "option" ~ nothing.

          I agree with Ryan and John,

          If there is no metal piping system, then there is nothing to bond.

          680.74 requires all metal piping systems and all grounded metal parts in contact with the circulating water to be bonded together.

                  680.74

                  Hi: To answer the particulars of your poll... IMO, the idea of 680.74 is to establish an equipotential plane around the tub similar to swimming pool bonding grids and agricultural equipotential planes. The equipment grounding conductor of the pump motor takes care of ground-fault currents. No need to extend bonding conductor to panelboard or service equipment.

                    I agree with others. Nothing required IMHO.

                        I wonder how many pages this can go with everyone agreeing?

                            No further action required for this situation.


                            Oops this was a poll for inspectors.
