What protective measure is commonly required for receptacles in wet locations according to the NEC®?

In wet locations, the National Electrical Code (NEC) specifies that receptacles must have ground fault circuit interrupter (GFCI) protection. This requirement is critical because GFCIs are designed to prevent electric shock by monitoring the current flow and cutting off the electricity supply if an imbalance occurs. When a GFCI detects that current is leaking to ground (potentially through a person who is grounded), it reacts quickly to shut off power, greatly reducing the risk of electrical shock, which is particularly hazardous in wet or damp conditions.

This protective measure enhances safety in environments such as bathrooms, kitchens, outdoor areas, and any other locations where the likelihood of water contact with electrical equipment is high. GFCIs are specifically engineered for these circumstances, reflecting the NEC’s focus on safeguarding individuals in potentially dangerous electrical situations.

Other options, like fuse protection and surge protectors, serve different purposes, such as protecting against overcurrent and voltage spikes, respectively, but they do not specifically address the risks associated with wet locations like GFCIs do. Isolation transformers are also not applicable as a protective measure for receptacles in wet environments; they are primarily used to isolate electrical equipment or to provide specific safety benefits in certain applications, not for general receptacle
