Section E4207 Storable Swimming Pools, Storable Spas, and Storable Hot Tubs

A cord and plug-connected pool filter pump for use with storable pools shall incorporate an approved system of double insulation or its equivalent and shall be provided with means for grounding only the internal and nonaccessible noncurrent-carrying metal parts of the appliance.

The means for grounding shall be an equipment grounding conductor run with the power-supply conductors in a flexible cord that is properly terminated in a grounding-type attachment plug having a fixed grounding contact. Cord and plug-connected pool filter pumps shall be provided with a ground-fault circuit interrupter that is an integral part of the attachment plug or located in the power supply cord within 12 inches (305 mm) of the attachment plug. (680.31)

Electrical equipment, including power-supply cords, used with storable pools shall be protected by ground-fault circuit-interrupters. 125-volt, 15- and 20-ampere receptacles located within 20 feet (6096 mm) of the inside walls of a storable pool, storable spa, or storable hot tub shall be protected by a ground-fault circuit interrupter. In determining these dimensions, the distance to be measured shall be the shortest path that the supply cord of an appliance connected to the receptacle would follow without passing through a floor, wall, ceiling, doorway with hinged or sliding door, window opening, or other effective permanent barrier. (680.32)

Luminaires for storable pools, storable spas, and storable hot tubs shall not have exposed metal parts and shall be listed for the purpose as an assembly. In addition, luminaires for storable pools shall comply with the requirements of Section E4207.3.1 or E4207.3.2. (680.33)

A luminaire installed in or on the wall of a storable pool shall be part of a cord and plug-connected lighting assembly. The assembly shall:

1. Have a luminaire lamp that is suitable for the use at the supplied voltage;

2. Have an impact-resistant polymeric lens, luminaire body, and transformer enclosure;

3. Have a transformer meeting the requirements of section E4206.1 with a primary rating not over 150 volts; and

4. Have no exposed metal parts. [680.33(A)]

A lighting assembly without a transformer or power supply, and with the luminaire lamp(s) operating at over the low-voltage contact limit, but not over 150 volts, shall be permitted to be cord and plug-connected where the assembly is listed as an assembly for the purpose and complies with all of the following:

1. It has an impact-resistant polymeric lens and luminaire body.

2. A ground-fault circuit interrupter with open neutral conductor protection is provided as an integral part of the assembly.

3. The luminaire lamp is permanently connected to the ground-fault circuit interrupter with open-neutral protection.

4. It complies with the requirements of Section E4206.4.

5. It has no exposed metal parts. [680.33(B)]

Receptacles shall be located not less than 6 feet (1829 mm) from the inside walls of a storable pool, storable spa or storable hot tub. In determining these dimensions, the distance to be measured shall be the shortest path that the supply cord of an appliance connected to the receptacle would follow without passing through a floor, wall, ceiling, doorway with hinged or sliding door, window opening, or other effective permanent barrier. (680.34)

Overhead conductor installations shall comply with Section E4203.6 and underground conductor installations shall comply with Section E4203.7.

Disconnecting means for storable pools and storable/portable spas and hot tubs shall comply with Section E4203.3.

Ground-fault circuit interrupters shall comply with Section E4206.2.

Equipment shall be grounded as required by Section E4205.1.

Electric pool water heaters shall comply with Section E4206.12.
