Question: A hot tub (red wood, not self-contained) that sits on an existing concrete deck that will have a 2 foot high wooden deck surrounding it for more than 3 feet out. Where does the equipotential bonding grid go? (It is not self-contained because the pumps are supplied with the unit but are not plumbed in. Is this a correct interruption of self-contained?)
Equipotential Bonding Grid Placement
The equipotential bonding grid should be installed around the perimeter of the wooden deck,
at least 18 inches away from the inside edge of the deck. It should be attached to the concrete deck using bonding jumpers connected to the ground rod.
Criteria for "Self-Contained":
A hot tub is considered self-contained if it meets all of the following criteria: It has an integral (built-in) pump, filter, and heater. It is designed to be installed directly on a concrete pad without the need for additional pumps or plumbing connections.* It has a Ground-Fault Circuit Interrupter (GFCI) built into the control panel.In this case, the hot tub is not self-contained because the pumps are supplied with the unit but are not plumbed in. Therefore, the equipotential bonding grid must be installed as described above. Flag for review
