Question: 1 / 400

Where must ground-fault circuit-interrupter (GFCI) devices be installed according to NEC® requirements?

In a hidden location

In an area difficult to access

In a readily accessible location

Ground-fault circuit-interrupter (GFCI) devices are required to be installed in a readily accessible location to ensure that users can easily reach them for testing and resetting. This accessibility is crucial because GFCIs are designed to enhance safety by quickly responding to ground faults, which can lead to electric shock. If these devices are hard to reach or located in hidden or difficult areas, it could pose a significant risk to users, as they may not be able to promptly reset the device when necessary or test its function regularly.

The National Electrical Code (NEC) emphasizes the importance of accessibility so that individuals can maintain and check these essential safety devices without undue difficulty. This ensures that the GFCI can be properly used to prevent electrical hazards, fulfilling its role in protecting people from potential electric shock, especially in high-risk areas such as kitchens, bathrooms, and outdoor locations.
