What is identified when marking GFI receptacles on the exterior of a building?

Marking GFI (Ground Fault Interrupter) receptacles on the exterior of a building is primarily associated with identifying Ground Fault Protection Locations. GFI receptacles are specifically designed to prevent electrical shock by monitoring the flow of electricity and shutting off the circuit if an imbalance is detected. This is crucial in exterior locations where moisture may be present, increasing the risk of ground faults.

Properly marking these locations ensures that installers, maintenance personnel, and homeowners are aware of where ground fault protection is implemented, highlighting areas that require specific safety considerations. This marking is essential for compliance with electrical codes and safety regulations, as it provides necessary information for safe usage and maintenance.

The other options, while important in the overall construction context, do not specifically relate to the identification of GFI receptacles. Lighting installations pertain to the design of lighting systems rather than receptacle safety, electrical load assessments focus on capacity and demand calculations within a system, and receptacle types for resale do not convey the safety-related information associated with GFI protections.
