5 Ways to Keep Outdoor Extension Cord Connections Safe and Dry
Use a GFCI outlet or adapter A GFCI is non-negotiable for outdoor power. It trips the breaker if water causes a short, protecting you from electrocution.
Keep the plug junction off wet ground The real risk is where two plugs meet, not the cord jacket. Water can wick into that joint and cause a short, so elevate it.
Use an upside-down plastic container Place the connection inside a small plastic container like a Tupperware or cut-off milk jug, flipped upside down with the cord coming out through a notch. Weigh it down with a brick.
Drape a plastic bag as a quick fix Tape a plastic bag around the cord over the connection. It is not perfect but works for a few hours in a pinch.
Never compromise on safety Water and electricity do not mix. A GFCI and a dry, elevated joint are your only real defenses.
