Exterior receptacles are required to have which type of protection?

• A. Circuit surge protection
• B. Extra wire
• C. AFI protection
• D. GFCI protection

Answer: (D)

Exterior receptacles are required to have GFCI (Ground Fault Circuit Interrupter) protection to ensure safety in wet or damp areas. GFCI devices are specially designed to protect individuals from electric shock by monitoring the flow of electricity and quickly shutting off the circuit if an imbalance occurs, which can happen if there is a ground fault. This is particularly important for outdoor receptacles because they are often exposed to moisture from rain or other environmental factors, increasing the risk of accidents.

GFCI protection is mandated by electrical codes for all outdoor outlets to mitigate hazards and enhance safety for users who may be operating electrical equipment in less-than-ideal conditions. This requirement reflects the understanding that water and electricity can be a dangerous combination, and the implementation of GFCIs significantly reduces the risk of electrocution from exterior electrical installations.
