GFCI and AFCI outlets have two sets of terminals (two sides). The line side connects to line voltage, the load side can connect to other outlets that will have the same protection.

Power is connected to the GFCI line side as shown. The load side of the GFCI will have yellow tape over it and is not connected in the diagram below.

Can I Install a GFCI or AFCI without a Ground Wire?

Yes, they will work properly if there is no ground. A plug tester with a GFCI test button will not trip a GFCI because the tester leaks a small amount of current from line to ground. The GFCI and AFCI test button is used for testing.

GFCI Adapters

A GFCI adapter can be used on a standard outlet. Plug the adapter into an outlet and anything you plug into the adapter will have GFCI protection.
