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.

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

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