Question

Hydromassage tubs and all of their electrical components ____ GFCI protected

a. shall be
b. must be
c. can be
d. are optional

Answer 1

Hydromassage tubs and all of their electrical components should be GFCI protected to prevent electrical hazards, complying with the NEC safety requirements.

Step-by-step explanation:

The electrical components of hydromassage tubs, according to the National Electrical Code (NEC), shall be GFCI (Ground Fault Circuit Interrupter) protected. This is a safety requirement to prevent electrocution and electrical shock hazards, especially since water conducts electricity and can pose a significant risk in wet environments. GFCI outlets quickly shut off power if they detect a ground fault, which occurs when there is an unintended electrical path between a power source and a grounded surface.

Answer 2

Hydromassage tubs and all of their electrical components must be GFCI protected. Option B is the answer.

Step-by-step explanation:

The use of "must be" in the context of electrical safety regulations indicates a mandatory requirement. For hydromassage tubs and their electrical components, GFCI (Ground Fault Circuit Interrupter) protection is essential. GFCIs are designed to quickly interrupt the flow of electricity in the event of a ground fault, providing an added layer of safety by preventing electrical shocks.

Given the potential combination of water and electricity in hydromassage tubs, the requirement for GFCI protection is crucial to minimize the risk of electric shock hazards. Adherence to this requirement ensures compliance with electrical safety standards and promotes the safe use of hydromassage tubs in residential and commercial settings.

Option B is the answer.
