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

Switches must be at least ____ ft. from the inside wall of a spa or hot tub.

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.

Drownings have occurred when a person is trapped under water by the tremendous ____ at an unprotected drain in a swimming 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.

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.

At least one 125-volt, 15- or 20-amp GFCI-protected receptacle must be installed no closer than ____________________ ft but not farther than 10 ft from the inside wall of a spa or hot tub.

Where there are no metal parts in contact with pool water, there still is a need to bond the water to the pool deck to eliminate voltage gradients between the pool water and the deck.

Where there are no metal parts in contact with pool water, there still is a need to bond the water to the pool deck to eliminate voltage gradients between the pool water and the deck.

Switches must be at least ____ ft. from the inside wall of a spa or hot tub.

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

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

At least one 125-volt, 15- or 20-amp GFCI-protected receptacle must be installed no closer than ____________________ ft but not farther than 10 ft from the inside wall of a 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.

The branch-circuit conductor ampacity and the rating of the branch-circuit overcurrent devices must not be less than ____ percent of the total nameplate rated-load ampere rating of an electric pool water heater.

The purpose of bonding together all metal parts and other conductive surfaces that are part of, in, and around a permanently installed swimming pool is to ____ voltage gradients in the pool and adjacent areas around the pool.

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.

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 purpose of bonding together all metal parts and other conductive surfaces that are part of, in, and around a permanently installed swimming pool is to ____ voltage gradients in the pool and adjacent areas around the pool.

The branch-circuit conductor ampacity and the rating of the branch-circuit overcurrent devices must not be less than ____ percent of the total nameplate rated-load ampere rating of an electric pool water heater.

Drownings have occurred when a person is trapped under water by the tremendous ____ at an unprotected drain in a swimming pool.
