Eight Things Never to Do With an Extension Cord

Selecting extension cords

• Purchase only cords that have been approved by an independent testing laboratory.
• For outdoor projects, use only extension cords marked for outdoor use.
• Read the instructions (if available) for information about the cord’s correct use and the amount of power it draws when running.
• Select cords that are rated to handle the wattage of the devices with which they’ll be used. A cord’s gauge indicates its size: The smaller the number, the larger the wire and the more electrical current the cord can safely handle.
• Also consider the length you’ll need. Longer cords can’t handle as much current as shorter cords of the same gauge.
• Choose cords with polarized or three-prong plugs.
• For use with larger appliances, thick, round, low-gauge extension cords are best. For smaller appliances and electronics, you can use thin or flat cords.

Using extension cords

• Never remove an extension cord’s grounding pin in order to fit it into a two-prong outlet.
• Never use extension cords to power appliances. Plug appliances directly into wall outlets. .

• Don’t plug multiple cords together.
• Don’t run extension cords under rugs or furniture.
• Never tape extension cords to floors or attach them to surfaces with staples or nails.
• Don’t bend or coil cords when they’re in use.

Caring for extension cords

• Always store cords indoors.
• Unplug extension cords when they’re not in use.
• Throw away damaged cords.
• Pull the plug—not the cord—when disconnecting from the outlet.
• Consider covering unused cord receptacles with childproof covers.
