Where are GFCI outlets required by 2026 NEC code?

GFCI protection is required in bathrooms, kitchens (within 6 feet of any sink), garages, unfinished basements, crawl spaces, laundry rooms, outdoor outlets, and any outlet within 6 feet of a wet bar, utility sink, or slop sink. All 2026 new construction also requires GFCI on kitchen countertop and island receptacles regardless of distance.

What is the difference between LINE and LOAD terminals on a GFCI outlet?

LINE terminals bring power from the breaker panel. LOAD terminals carry protected power to downstream outlets. Wires on LOAD are protected by the GFCI — if a downstream outlet trips the GFCI, it's a LOAD connection. Wires on LINE are the incoming power and are not protected. Mistaking the two leaves downstream outlets unprotected.

Can I install a GFCI outlet on an ungrounded two-wire circuit?

Yes. The 2026 NEC allows GFCI outlets on two-wire circuits with no ground, as long as the outlet is labeled 'No Equipment Ground.' The GFCI still provides shock protection — it detects leakage current between hot and neutral even without a ground path. Install the sticker that comes in the box on the faceplate.

How do I test a GFCI outlet after installation?

Press the TEST button — the outlet should click and the RESET button should pop out. Plug in a GFCI tester (three-light style) and press its test button — the GFCI should trip. If the RESET button does not pop or power stays on at the tester, the GFCI is wired incorrectly. Check your LINE vs. LOAD connections.
