4 Things to Know About Two-Prong Adapters and Extension Cords

A two-prong adapter does not add grounding to an extension cord The adapter is meant for two-prong outlets, not for creating a ground path through a cord. Its metal tab must be screwed into a properly grounded outlet cover plate, which is already unreliable.

Using a two-prong adapter on an extension cord breaks the ground path entirely Even if the outlet is grounded, adding an extension cord between the adapter and the appliance disconnects the ground. This turns the setup into a fire hazard.

Use a three-prong extension cord with a grounded three-prong outlet instead If your appliance needs grounding, plug a three-prong cord directly into a properly grounded outlet. Do not rely on adapters.

For two-prong outlets, update the outlet or use a GFCI adapter A GFCI adapter provides shock protection but not a true ground. The only safe fix is having an electrician install a grounded outlet.
