For hydromassage bathtub bonding, the conductor must be copper and at least 8 AWG.

• A. True
• B. False
• C. Only If Indoors
• D. Only If Outdoors

Answer: (A)

Bonding for a hydromassage tub is about creating an equipotential path so all metal parts that could become energized are at the same electrical potential, reducing the risk of shock if a fault occurs. The NEC requires the bonding conductor to be copper and at least 8 AWG in size, no matter whether the installation is indoors or outdoors. This minimum size provides a low-impedance path back to the grounding system, ensuring effective bonding. Using anything smaller or a non-copper material would not meet the requirement and could compromise safety.
