HOLIDAY DECORATION
ELECTRICAL SAFETY.
Christmas-light fires are uncommon but predictable — they happen from the same three or four mistakes every year. Here is how to avoid them.
1. Check the UL rating before plugging in
Lights rated for indoor use only often say so on the tag. Using them outdoors exposes them to moisture they were not built to handle. Outdoor-rated strings have sealed bulbs, UL "outdoor" or "indoor/outdoor" labels, and typically feature heavier cord insulation.
2. Use GFCI outlets for anything outside
Florida code has required GFCI-protected outdoor receptacles for years. If your exterior outlets are older three-prong outlets without a GFCI, add protection before the holidays — either a GFCI receptacle at the outlet or a GFCI breaker at the panel.
3. Do not daisy-chain extension cords
Every manufacturer publishes a maximum number of strings you can connect end-to-end — usually three to five for incandescent, more for LED. Exceeding that limit overloads the first cord in the chain. And never chain extension cords together to reach farther; the voltage drop and heat buildup are exactly what starts fires.
4. Staples, nails, and string insulation
Never fasten light strings with staples or nails driven through the cord. Use listed clips that do not pierce the insulation. One pierced wire rubbing on a gutter is enough to start a short.
5. Unplug when you leave the house
Timers with built-in GFCI indicators let you set-and-forget. Plain timers that run the lights all night with no one home are the highest-risk setup. The modern answer is a smart plug with a timer function and remote shutoff.

The one thing almost everyone does wrong
Running decoration load off a kitchen or bathroom GFCI "because it is the closest outlet" — and then losing the protection the GFCI exists to provide because a wet decoration keeps tripping it, so the homeowner resets it with damp hands. Dedicate outdoor decorations to an outdoor outlet.
