What type of protection is required for a whirlpool tub according to NEC regulations?

No protection required
Standard circuit protection
GFCI protection
Surge protection

The correct answer is: GFCI protection

Whirlpool tubs are classified as wet locations, which present a risk of electric shock due to their proximity to water. According to the National Electrical Code (NEC), the use of Ground Fault Circuit Interrupter (GFCI) protection is mandatory for equipment that operates in such conditions. GFCIs are specifically designed to protect people from electric shock by monitoring the electrical current flowing through the circuit and quickly shutting the power off if an imbalance is detected. This protection is particularly crucial for appliances and fixtures like whirlpool tubs that can expose users to electrical hazards in wet environments. By utilizing GFCI protection, the risk of electric shock or electrocution is significantly reduced, making it a critical requirement for the safe operation of these tubs.
