Exam 30: Swimming Pools, Spas, Hot Tubs, and Hydromassage Baths

A self-contained spa or hot tub assembly may be connected using a wiring method that contains a copper equipment-grounding conductor not smaller than ____ AWG.

The wiring for storable pools must follow the basic requirements found in ____________________, Part 1.

The shock hazard to a person in a pool is quite different from that of the normal "touch" shock hazard to a person not submersed in water. The water makes contact with the entire skin surface of the body rather than just at one "touch" point.

Once you run conductors beyond (on the load side of) a GFCI device protecting that wiring, you are not permitted to have other conductors in the same raceway, box, or enclosure. Give two exceptions to this rule.

Underground wiring is not permitted under pools or within ____ horizontally from the inside walls of a pool.

Do not bond together metal raceways, metal piping, and other metal surfaces within 5 ft (1.5 m) of the inside walls of the spa or hot tub, unless separated by a permanent barrier, such as a wall or building.

Components that must be bonded include ____.

Tests conducted over the years have shown that a voltage gradient of ____ volts per foot can cause paralysis.

We are permitted to use a flexible cord-and-plug connection for fixed or stationary equipment associated with a permanently installed pool. Underwater luminaires are included in this permission.

A receptacle that supplies power to a spa or hot tub must be ____.

Components that must be bonded include ____.

The shock hazard to a person in a pool is quite different from that of the normal "touch" shock hazard to a person not submersed in water. The water makes contact with the entire skin surface of the body rather than just at one "touch" point.

The wiring for storable pools must follow the basic requirements found in ____________________, Part 1.

A hydromassage bathtub constitutes more of a shock hazard than a regular bathtub.

A clearly labeled emergency shutoff switch for the control of the recirculation system and jet system for spas and hot tubs must be installed at a point readily accessible to the users and not less than ____________________ away and within sight of the spa or hot tub.

UL Standard 1563 establishes the maximum water temperature at 104 degrees F, and the suggested maximum time of immersion is generally ____________________ minutes.

Tests conducted over the years have shown that a voltage gradient of ____ volts per foot can cause paralysis.

Underground wiring is not permitted under pools or within ____ horizontally from the inside walls of a pool.
