NEC Article 210.8 A Explained: GFCI Rules for 2026
NEC Article 210.8 A, written 210.8(A) in the code book, is the list of dwelling unit locations where GFCI protection is required. This guide explains what the list says, how it changed between the 2020, 2023 and 2026 editions, what 210.8(C) and 210.8(D) add, and when you can simply swap a regular outlet for a GFCI. A one-page PDF cheat sheet is included.
Quick answer: NEC Article 210.8 A requires GFCI protection for personnel on 125 to 250 volt receptacles in dwelling unit bathrooms, garages, outdoors, crawl spaces, basements, kitchens, near sinks and tubs, boathouses and laundry areas, when supplied by single-phase circuits of 150 volts or less to ground.
What Is Article 210 in the NEC, and Where Does 210.8 Fit?
Article 210 is the NEC article on branch circuits: ratings, conductors, required outlets and protection. Section 210.8 is its ground-fault protection section, and it is split into six parts:
| Part | Covers |
|---|---|
| 210.8(A) | Dwelling units (receptacles) |
| 210.8(B) | Other than dwelling units |
| 210.8(C) | Crawl space lighting outlets |
| 210.8(D) | Specific appliances |
| 210.8(E) | Receptacles for equipment requiring servicing |
| 210.8(F) | Outdoor outlets at dwellings |
Letters and wording shift between editions, so confirm against the edition your jurisdiction enforces.
What Does NEC Article 210.8 A List?
Section 210.8(A) lists the dwelling unit locations below. Every 125 to 250 volt receptacle in them, on a single-phase circuit of 150 volts or less to ground, needs a listed GFCI (Class A) device:
- Bathrooms
- Garages, and accessory buildings with floors at or below grade (non-habitable storage and work areas)
- Outdoors
- Crawl spaces at or below grade
- Basements
- Kitchens
- Areas with sinks, within 6 ft of the sink edge
- Boathouses
- Within 6 ft of a bathtub or shower stall
- Laundry areas
The distance is measured along the shortest path a cord would take, not in a straight line through walls. The 2023 edition widened kitchens to all kitchen receptacles and expanded sink areas. Some states amend these, so check local rules.
NEC Article 210.8 A (3): What Protection Do Outdoor Receptacles Need?
In the 2020 and 2023 editions, item (3) of NEC Article 210.8 A is outdoors, and the answer is GFCI protection for personnel. Outdoor receptacles also need to be weather resistant and have a weatherproof in-use cover. The 2026 edition separates garages from accessory buildings, which moves outdoors to a different item number, so cite the edition when you cite the item.
Separately, 210.8(F) covers outdoor outlets that are not receptacles, such as outdoor HVAC disconnect outlets, with exceptions for lighting. For mounting and device rules, see our guide to the NEC code for outlet orientation.
NEC Article 210.8 A 2021, 2022 and 2026: Which Edition Applies?
There is no 2021 or 2022 NEC. Editions come every three years: 2017, 2020, 2023 and 2026. When people search NEC Article 210.8 A 2021 or 2022, they usually mean the 2020 edition, which many states still enforce.
| Edition | What changed for GFCI |
|---|---|
| 2020 | New (E) for equipment-servicing receptacles and (F) for outdoor outlets; (D) for specific appliances such as dishwashers |
| 2023 | All kitchen receptacles covered; (D) list expanded; (F) widened to garages, accessory buildings and boathouses |
| 2026 | Garages separated from accessory buildings; accessory building rule narrowed; Class A wording |
Summaries of the 2026 text vary, so read it on NFPA’s free access page.
NEC 210.8 C and 210.8 D: Crawl Spaces and Specific Appliances
For the common search nec 210.8 c, the answer is crawl space lighting outlets: GFCI protection for lighting outlets of 120 volts or less installed in crawl spaces. In the 2017 edition the same idea sat in a different letter, so match the letter to the edition.
What is now included in section 210.8 D, specific appliances? It points to the appliance list in 422.5, and the 2023 edition expanded it to include electric ranges, wall-mounted ovens, counter-mounted cooking units, clothes dryers and microwave ovens, in addition to dishwashers. The rule applies to the branch circuit or outlet for appliances rated 150 volts or less to ground and 60 amps or less. Confirm the full list in your edition.
EV charging has its own GFCI rule in Article 625, so read our guide to hardwired vs plug-in EV chargers and size the circuit with the EV charger cable size calculator.
Can I Just Replace a Regular Outlet With a GFCI?
Usually yes. NEC Article 210.8 A applies to replacements too, because 406.4(D)(3) requires GFCI protection when you replace a receptacle in a location that needs it. Check these first:
- Ground wire: with no equipment ground, 406.4(D)(2) lets you fit a GFCI marked “No Equipment Ground”. Do not use a plain grounding-type device.
- Line and load: feed the LINE terminals from the panel, or downstream outlets will not be protected.
- Box fill: a GFCI is bulkier, so check the box volume under 314.16.
- Tamper resistance: if TR applies in that room, the replacement must be TR (406.4(D)(5)).
Then press TEST and RESET. For wiring and breaker questions, see our NEC requirements for ground fault protection and NEC article for grounding and bonding.
What Should You Never Plug Into a GFCI Outlet?
The NEC does not ban devices from GFCI outlets, but manufacturers advise against plugging in life-support or critical medical equipment, because a trip cuts power without warning. If a freezer or sump pump nuisance trips, fix the cause rather than bypassing protection.
