GFCI Requirements for Outdoor Eave Lights

When installing or updating outdoor eave lights, understanding GFCI (Ground-Fault Circuit Interrupter) requirements is essential for both safety and code compliance. These lights are exposed to rain, humidity, and temperature changes—making GFCI protection a smart choice, and often a legal one.

Under the National Electrical Code (NEC), the rules depend on how the lights are connected. If your eave lights plug into an outdoor receptacle, that receptacle must be GFCI-protected per NEC 210.8(A) (for 15A or 20A, 125V circuits). This applies regardless of whether the receptacle is under the eave.

For hardwired eave lights (directly connected to wiring), the NEC does not explicitly require GFCI protection for the lighting circuit itself—unless the fixture is located in a “wet” or “damp” location. Eaves are typically considered damp or wet due to wind-driven rain. Many local codes now interpret this as requiring GFCI protection for the entire outdoor lighting circuit. Additionally, NEC 410.10(A) mandates that fixtures in damp/wet locations be marked for such use, but GFCI isn’t always mentioned separately.

Best practice? Install a GFCI breaker for the circuit feeding your eave lights. It adds affordable protection against shocks and meets most local code updates (e.g., 2020 NEC expands GFCI requirements for outdoor outlets and equipment). Always check with your local building department—requirements vary by jurisdiction. When in doubt, call a licensed electrician. Safety under the eaves is worth the extra step.
