What outdoor GFCI outlet means
An outdoor GFCI outlet is a ground-fault protected receptacle in a weatherproof cover, the power source for most holiday displays and landscape lighting.
Where it matters on a holiday lighting job
Displays trip GFCIs when connections get wet. Use covers rated for in-use cords and raise connections off the ground. If the house has too few outdoor outlets, refer an electrician rather than chaining cords.
What the model code says
- The code requires at least one outdoor receptacle at the front and back of each dwelling with direct access to grade, reachable from grade and not more than 6 feet 6 inches above it. (IRC 2021, Chapter 39)
