4 Things to Know About Extension Cords for Well Pumps

Use a heavy-gauge, short extension cord Well pumps draw a startup surge 2–3 times their running amps. A standard household cord will cause voltage drop and can burn out the motor.

Match the gauge to the pump and distance Use at least 12-gauge for a 15-amp pump. Step up to 10-gauge if the run exceeds 25 feet.

Only use outdoor-rated, three-wire grounded cords The cord must be rated for outdoor use and have a ground prong. Anything less is unsafe.

Extension cords are for temporary testing only For permanent installations, hardwire the pump per code. Do not rely on an extension cord long-term.
