Understanding NEC 2023 GFCI Rule Changes (Section 210.8 Explained)
Answering Your Core Question: What Are the NEC 2023 GFCI Requirements?
The 2023 National Electrical Code (NEC) expands Ground-Fault Circuit-Interrupter (GFCI) protection requirements under Section 210.8 to enhance personnel safety. The most important change for dwelling units is in 210.8(A), which now requires GFCI protection for 125-volt through 250-volt receptacles in the locations listed (including kitchens), removing the earlier countertop-only phrasing and expanding the scope of receptacles in those locations. Certain specific appliances (listed under 210.8(D)) are covered when the branch circuit or receptacle supplying them is rated 150 volts or less to ground and 60 amperes or less; that list can include items such as clothes dryers and electric ranges when they meet those criteria. For “Other Than Dwelling Units” (210.8(B)), the list of locations requiring GFCI protection has grown to include additional non-dwelling sink and food-preparation areas and other spaces identified by the code.
A Foundational Shift: What Drove the 2023 GFCI Updates?
As professional electricians, we know the NEC is not a static document. It’s a living code that evolves based on field data, technological advances, and a continuing drive to improve electrical safety. The revisions to NEC 2023 Section 210.8 came through the regular code-making process (Code-Making Panel work) with the primary goal of reducing serious shock and electrocution incidents. Expanding GFCI requirements targets locations where contact with water, conductive surfaces, or powerful appliances increases the risk of ground faults—so the code provides greater personnel protection in those higher-risk areas.
Key Changes in NEC 2023 Section 210.8: A Detailed Breakdown
The 2023 cycle introduced pivotal changes that affect daily installation practices. Here’s a practical breakdown of the most impactful revisions.
Dwelling Unit Requirements (210.8(A)): The Kitchen “Countertop” Clause is Clarified
In previous NEC editions, 210.8(A) focused on receptacles serving kitchen countertop surfaces and other specific locations. The 2023 NEC clarifies that receptacles in the locations listed in 210.8(A) (kitchens among them) require GFCI protection. That change reduces ambiguity about whether a receptacle in a kitchen but away from the countertop is covered.
Appliance GFCI Requirements: Targeted Protection for Specific Equipment
Another important expansion involves specific appliances. Section 210.8(D) addresses appliances supplied by a branch circuit or outlet and applies when the appliance circuit meets the criteria in the code (notably, branch circuits or outlets that supply appliances “rated 150 volts or less to ground and 60 amperes or less”). When those conditions are met, the listed appliances (which can include clothes dryers and ranges under the specified limits) require GFCI protection for the branch circuit or outlet that supplies them. This is why, for a cord-and-plug connected 240V dryer in a laundry area, the GFCI question must be evaluated under both the location rules in 210.8(A) and the appliance-supply rules in 210.8(D).
Other Than Dwelling Units (210.8(B)): Expanding Commercial Protection
Requirements for non-dwelling spaces in 210.8(B) were also clarified and expanded. Several categories of work and public spaces are now explicitly listed so that receptacles in break-room kitchens, employee food-prep areas, and similar non-residential locations are covered by GFCI protection when they meet the item descriptions in the code. This helps ensure consistent protection in many commercial settings.
These GFCI updates are one part of broader changes in how the 2023 NEC handles outlets and switches. For more on how these changes fit with the broader changes to lighting and outlet requirements in the 2023 code, a comprehensive review is essential for maintaining compliance.

Practical Application: Determining GFCI Needs for New Appliances
Let’s apply a clear check for whether a 240V clothes dryer in a new home requires GFCI protection under the 2023 NEC. This example focuses on a cord-and-plug connected appliance, since Section 210.8 applies to receptacles:
- Identify the Location: The appliance is in a “laundry area” as defined by Article 100.
- Consult NEC 210.8(A): Review the list of locations for dwelling units. Item (10) explicitly lists “Laundry areas,” so location-based GFCI rules apply.
- Check Appliance/Outlet Criteria: If the branch circuit or outlet supplying the dryer is within the appliance-protection criteria (appliance branch circuit/receptacle rated 150 volts or less to ground and 60 amperes or less) or the receptacle is covered by the location rules in 210.8(A), then GFCI protection is required.
- Determine Protection Method: For a 240V dryer supplied via a receptacle, the typical method is a 2-pole GFCI circuit breaker (or a listed GFCI receptacle if code-permitted for that application), which provides the branch-circuit protection required by the NEC.
- Verify Accessibility: Ensure the GFCI device (for example, a breaker in the panel) is readily accessible for testing and resetting, as required by the code.
Following this step-by-step approach ensures electrical code compliance and avoids inspection issues.
Addressing Industry Concerns: Nuisance Tripping and Accessibility
Concerns about potential nuisance tripping when applying GFCI protection to motor-driven or high-current appliances are common. Modern GFCI devices and proper appliance design reduce nuisance trips, and appliance manufacturers are updating products to be compatible with GFCI protection. Installers should follow the code and manufacturer guidance. In some situations a listed 2-pole GFCI breaker is the appropriate branch-circuit solution and keeps the protection accessible and resettable.
Spotlight on Outdoor Outlets: NEC 210.8(F)
The 2023 code clarified 210.8(F): GFCI protection is required for outdoor receptacles at dwelling units supplied by single-phase branch circuits rated 150 volts to ground or less and 50 amperes or less. That covers many typical outdoor receptacles used for lawn equipment, landscape lighting convenience outlets, and similar uses when they meet the circuit rating criteria. There is an explicit NEC exception for listed HVAC equipment (a limited-time exception in the code text), so HVAC receptacles are treated differently until that exception expires (check the local adoption and the NEC edition adopted in your jurisdiction).

Key Takeaways for NEC 2023 GFCI Compliance
- Kitchens are clarified: Receptacles in the kitchens listed by 210.8(A) require GFCI protection; the countertop-only wording has been removed to reduce ambiguity.
- 250V receptacles: 125- through 250-volt receptacles in the locations listed in 210.8(A) and (B) are within the scope; appliance-specific protection in 210.8(D) applies when the supplying branch circuit or outlet is rated 150 volts or less to ground and 60 amperes or less.
- Specific appliances: The code lists appliances that require protection when the circuit/ outlet meets the voltage-to-ground and ampere criteria; dryers and ranges can be included when those criteria are met.
- Commercial kitchens & non-dwelling areas: Many non-dwelling food-preparation, break-room, and sink areas are explicitly included in 210.8(B).
- Check local adoption and exceptions: Verify whether your jurisdiction has adopted NEC 2023 and whether any exceptions (for example, the limited HVAC exception) or local amendments apply.

Frequently Asked Questions about NEC 2023 GFCI Rules
Does the 2023 NEC require GFCI for all kitchen receptacles in a dwelling?
Yes. NEC 2023 Section 210.8(A) was revised so that if a receptacle is one of the receptacle locations listed (kitchens among them), 125-volt through 250-volt receptacles in those locations require GFCI protection. That removes the earlier narrow “countertop-only” phrasing and clarifies the location-based requirement.
What is the new GFCI rule for 250V receptacle protection?
The 2023 NEC expands coverage to receptacles up to 250 volts in the locations listed in 210.8(A) and (B). Additionally, 210.8(D) lists appliances for which GFCI protection is required when the supplying branch circuit or outlet is “rated 150 volts or less to ground and 60 amperes or less,” so the application depends on the combination of location and the appliance/circuit characteristics.
Is hard-wired equipment required to have GFCI protection?
Section 210.8 focuses on receptacles. Hard-wired equipment is not automatically covered by 210.8’s receptacle rules, but other NEC provisions may require GFCI or similar protection for specific hard-wired equipment or installations. Always check the applicable article for the specific equipment or the adopted edition in your jurisdiction.
