- Arc-fault circuit interrupter (AFCI)
- Ground-fault circuit interrupter (GFCI) (Correct answer)
- A dedicated isolation transformer
- Isolated ground receptacles
Correct answer: Ground-fault circuit interrupter (GFCI)
NEC 680.71 requires all electrical equipment associated with hydromassage bathtubs to be GFCI protected.
Question 2: Per NEC 680.41, the emergency shutoff or control switch for a spa or hot tub motor must be located at least how far from the unit?
- 3 feet
- 5 feet (Correct answer)
- 8 feet

- Metal water supply piping within 5 feet of the pool
- Reinforcing steel (rebar) in the pool shell
- Metal ladders and handrails
- PVC conduit supplying pool equipment (Correct answer)
Correct answer: PVC conduit supplying pool equipment
Non-metallic PVC conduit is not electrically conductive and is therefore not required to be included in the equipotential bonding system.

- Grounded (neutral) conductor at the panel
- Equipment grounding conductor of the panelboard (Correct answer)
- Grounding electrode at the service entrance
- Service entrance phase conductors
Correct answer: Equipment grounding conductor of the panelboard
NEC 680.26(D) requires the pool bonding system to be connected to the equipment grounding conductor of the panelboard supplying pool circuits.
Question 6: Per NEC 680.23(A)(4), no underwater pool luminaire shall be installed for operation at more than what maximum voltage between conductors?
- 30 volts
- 120 volts
- 150 volts (Correct answer)
- 240 volts
Correct answer: 150 volts
NEC 680.23(A)(4) limits underwater luminaires to a maximum of 150 volts between conductors.
Question 7: For storable (portable) swimming pools, receptacles providing power to the pump motor must be:
- Located at least 10 feet away with no other protection required
- Standard weatherproof receptacles with in-use covers
