When replacing a two-wire, nongrounding-type receptacle where the code requires a GFCI, what is it permitted to be replaced by?

When replacing a two-wire, nongrounding-type receptacle where the code requires a Ground Fault Circuit Interrupter (GFCI), it is permitted to be replaced by a GFCI receptacle. This option is correct because GFCI receptacles are specifically designed to provide protection against electrical shock in areas where moisture may be present, such as kitchens, bathrooms, and outdoor locations.

Using a GFCI receptacle in place of a standard receptacle enhances safety by monitoring the flow of electricity and quickly shutting off power if an imbalance is detected, which could indicate a ground fault. This is crucial in complying with electrical safety codes that require GFCIs in certain locations, especially when existing wiring does not include a ground. Furthermore, GFCI receptacles can be used safely with the existing two-wire system as they do not require a ground for operation.

This solution also allows for continued use of the circuit without needing to rewire or replace the entire circuit to incorporate a ground wire, making it a practical and code-compliant choice when upgrading existing installations.
