5 Things to Know About Outdoor Extension Cords for Pools and Spas

Get a cord with a built-in GFCI plug A ground fault circuit interrupter cuts power instantly if current leaks, preventing electrocution. Codes for pools and spas require GFCI protection at the outlet or on the cord itself.

Look for a “W” in the cord’s type rating The “W” in markings like SJTW or STW means weather-resistant, handling moisture and UV damage. Regular indoor cords will eventually fail or shock someone near water.

Check the packaging says “for outdoor use” Most outdoor cords sold today have a GFCI block built into the plug end, but verify the label explicitly states outdoor use and water resistance. The plastic boot on the plug is a nice extra, not a substitute.

Use the right gauge for your load 14-gauge works for medium loads like pumps or lights, while 12-gauge handles heavier equipment. Never use a cord without GFCI protection around water, regardless of gauge.

Never skimp on safety to save money A tiny break in a standard cord’s insulation can turn a puddle into a danger zone. Your life is worth more than saving ten bucks on a cord.
