Below are maps of the United States depicting what National Electrical Code year each state follows and when they will update their Code year as of 8/1/24.

# NEC Code Adoption by State as of 8/1/24

NEC (National Electrical Code) is fickle in the fact that although it comes out with a new Code every 3 years (including this year with their NEC Handbook 2023 edition) it takes time for each state to officially adopt a given Code year. Some states work to stay current (such as Massachusetts which has 2020 Code and is working on updating to 2023) while some states lag behind (Kansas has followed 2008 Code since 2008) and others leave it up to their counties or cities to decide what they follow (such as Arizona). There are also some odd stipulations, such as the state of New York following 2017 Code, but New York City follows 2008 Code. Here is a map of each state and which NEC Code year they follow as of 8/1/24.

# NEC Code Update by State as of 8/1/24

Another thing to keep in mind with NEC Code adoption is that it is an ongoing process. Not all states adopt new Codes right away (such as North Carolina having no plans to update their 2020 NEC currently), and some states can jump certain years altogether (Indiana is currently in the process of updating to 2023 Code from 2008 Code). Here is a map of what each state is planning on update wise currently.

National Electrical Code Article 422 handles specific appliance’s electrical needs. Learn more about what specific appliances require ground fault protection.

# What is NEC 422.5?

NEC Article 422.5 (the ground fault subsection of NEC 422) goes hand in hand with Article 210.8, as in where NEC 210.8 specifies GFCI protection requirements to the receptacles & outlets applied, NEC 422.5 specifies GFCI protection requirements for specific appliances, both plug-in or hardwired, as well as necessary locations requiring Class A GFCI protection. Updates in the language (that began in NEC 2020) also added that the protection on these appliances must be Class A (5+/- 1 mA trip level) protected. There are two subsections of NEC 422.5, Section A and B, and they include:

# NEC 422.5 (A)

Section A states there is 7 appliances that require Class A (between 4mA to 6mA ground fault threshold for electrical appliances rated up to 150 volts to ground & up to 60 Amps, single and/or 3-phase) GFCI protection according to this specific NEC classification. The appliances are as follows:

1.) Automotive vacuum machines

2.) Drinking water coolers & bottle fill stations

3.) Plug-in and hardwired high-pressure spray washing machines

4.) Tire inflation machines

5.) Vending machines

6.) Sump pumps

7.) Dishwashers

While there are more products that are required to have Class A protection (whether it be in terms of location or wiring configuration, always spelled out by the NEC in each specific Code Article) these are the 7 categories of standalone appliances that require Class A GFCI protection, per NEC guidelines.

# NEC 422.5 (B)

Section B dictates where and in what situations UL Listed Class A GFCI protection is required. There are 5 such locations according to this NEC classification, which are:

1.) Within a branch-circuit overcurrent device

2.) A device or outlet within the supply circuit

3.) An integral part of an attachment plug

4.) Within a supply cord that is no more than 12in (300mm) from the attachment plug

5.) Factory installed within the appliance.

These locations, again, work in conjunction with numerous other Codes. If your electrical appliance doesn’t meet any of these location requirements, you still need to make sure the appliance in its own right requires or doesn’t require Class A GFCI protection (x. kitchen equipment other than a dishwasher have their ground fault protection needs spelled out in NEC 210.8 (B)).

# What does this Code mean?

NEC 422.5 dictates what specific appliances and in what specific locations require UL Listed Class A GFCI protection. If it is outside the “scope” of a specific industry, NEC 422 is a good barometer to find out what named applications actually need GFCI protection and where it should be outfitted to meet NEC guidelines.

NEC Article 210.8 has multiple subsets that capture a wide range of industries for its guidelines on ground fault protection. Learn more about the Codes scope.

# What is NEC 210.8?

National Electrical Code (NEC) Article 210.8 has a variety of relevant subsets and captures a wide range of industries for its guidelines regarding electrical safety in each of these areas. We are going to take a closer look at each of these subsets, where they apply, and how NSS may be able to assist you in meeting these requirements.
NEC Article 210.8 (A): Subset A of NEC article 210.8 relates to all the areas in a dwelling (home) that require GFCI protection for 125-volt as well as 250-volt receptacles. This includes; kitchens, bathrooms, garages, basements, outdoors, boathouses, and laundry areas. This code was put into place to protect homeowners from encountering electrical shock hazards in wet environments in their homes. The best form of protection is through installing a GFCI within 6ft of running water regarding appliances they can come into contact with within their dwelling.

# NEC Article 210.8(A)

Subset A of NEC Article 210.8 relates to all the areas in a dwelling (home) that require GFCI protection for 125-volt as well as 250-volt receptacles. This includes; kitchens, bathrooms, garages, basements, outdoors, boathouses, and laundry areas. This code was put into place to protect homeowners from encountering electrical shock hazards in wet environments in their homes. The best form of protection is through installing a GFCI outlet within 6ft of running water for all appliances they can come into contact with inside a dwelling.

# NEC Article 210.8(B)

![NSS Products In Kitchen](30AMP60AMPAndPanel_ShowingOtherNSSProductsInKitchenFocusFront_1_A.webp)

Subset B of NEC Article 210.8 relates to non-dwelling (x. workplaces) areas that require GFCI protection. It has a larger range of electrical protection involved, including 125-volt and 250-volt receptacles supplied by single-phase branch circuits up to 50 Amps, and all receptacles supplied by three phase branch circuits supplying up to 100 Amps. There are numerous areas that require UL Listed GFCI protection (at or below the mentioned electrical configurations mentioned before), including; commercial kitchens, areas w/ sinks (involving food/beverage prep), buffet serving areas, bathrooms, sinks (where a receptacle or plug-in stationary appliance is located), rooftops, outdoors, indoor damp/wet locations, locker rooms, garages (accessory buildings, services bays & similar areas), aquariums (or similar open aquatic vessels/containers), and laundry areas. The updates to this Code (in 2020, with 2023 having similar language) have created a more demanding regiment of GFCI protection, especially in commercial kitchen environments with more language being added specifying where Class A protection is needed.

# NEC Article 210.8(D)

Subset D of NEC Article 210.8 relates to the specific appliances that require Class A GFCI protection on their respective supply outlets, up to 60 Amps, for single or 3-phase applications. This Article further reinforces NEC article 422.5(A), where it names 12 types of applications that require Class A protection to be an integral part of the appliances operation. These 12 applications include; vending machines, dishwashers, automotive vacuum machines, drinking watercoolers/bottle fill stations, pressure washers, tire inflation machines, electric ranges, sump pumps, wall-mounted ovens, microwave ovens, counter-mounted cooking units, and clothes dryers.

# NEC Article 210.8(F)

Subset F of NEC Article 210.8, which was a new addition to the 2020 code, relates to outdoor outlets of dwellings. This is where definitions start to get blurred, because outlets, according to NEC definition, are any point in a wiring system where the current is taken to supply equipment. So, this means that outdoor hardwired appliances (x. HVAC systems) require Class A GFCI protection. However, this Code has been amended during the 2020 code timeframe, specifically for HVAC equipment until 2026, because HVAC systems need to be updated to make sure that their systems can function properly with GFCI integration. In 2023 the language expanded to include garages, accessory buildings, and boathouses.

# What does this Code mean?

The main takeaway from this specific NEC Article is that you need Class A GFCI protection in most (if not all) areas of your home as well as in any workplace area that involves running water. It denotes the specific circuits that require protection as well as what appliances need that same protection. While you can find most of the 15-20 Amp GFCI’s for your home in receptacle outlet form, North Shore Safety can provide you with Class A GFCI products from 15-60 Amps single and three-phase to adhere to NEC Article 210.8 code requirements for your place of work, as well as at home (such as extension cord with added protection).

![2023-Code-Year-NEC-680](2023-Code-Year-NEC-680-display.webp)

NEC Article 680 mandates electrical protection guidelines of aquatic structures. Learn more about ground fault protection for pools, spas, fountains, and more.

# What is NEC 680?

NEC Article 680 and all of its subsets involve swimming pools, fountains, and similar installations. In particular, that means that this Article deals with the electrical protection of all equipment involved in swimming, wading, therapeutic, & decorative pools, fountains, hot tubs, spas, and hydromassage bathtubs. As in many other NEC Articles, there is mention of GFCI protection, but in NEC 680 there are many parts that involve specifications/needs of GFCI protection in this section (8 to be exact). Here are all 8 subsections, starting with:

# NEC Article 680.5

This section dictates the overarching reach of Ground-Fault Circuit-Interrupter (GFCI) and Special Purpose Ground-Fault Circuit-Interrupter (SPGFCI) protection. There are 3 parts to this subset, and they are as follows:

A.) This part, which is stated as “general”, just dictates that all GFCI and SPGFCI requirements in this Article must follow 210.8 (Class A protection) unless otherwise directed in the next 2 parts.
B.) This section is specified for the equipment that is not more than 150V to ground. In more detail, that is branch circuits not exceeding 150VAC to ground, 60A, and are single or three phase, need Class A GFCI protection.
C.) This part deals with equipment in excess of 150V to ground. In more detail, it’s for receptacles & outlet junctions on branch circuits operating at voltages greater than 150V to ground, although not exceeding a 480V maximum system voltage, shall be equipped with SPGFCI protection with a maximum trip setting of 20mA.

# NEC Article 680.21

![Pool at night](Pool_at_night.webp)

This subset of Article 680 deals with motors involved in pools. There are 2 parts in this subsection that have relation to GFCI & SPGFCI protection which includes:

C.) This article is for the ground fault protection of outlet junctions for pool motors. It states that pool pump motors need to have GFCI protection that comply with either 680.5(B) or (C) (based on voltage specifications).
D.) This part handles pool pump motor replacement or repair. If a motor is replaced/repaired, the installation must be provided with the proper GFCI or SPGFCI protection according to 680.5(B) or (C).

# NEC Article 680.22

This subsection deals with the lighting, receptacles, and equipment for permanently installed pools. further down in this section, part 680.22(B)(4), its states that there needs to be GFCI or SPGFCI protection in accordance with 680.5(B) or (C) for all “luminaries, lighting outlets, and ceiling-suspended (paddle fans)” that are between 5-10ft (1.5-3m) from the inside of a pools walls.

# NEC Article 680.32

This section was made to give specifications for GFCI and SPGFCI protection guidelines for all of the electrical equipment (x. power-supply cords), used with storable pools/hot tubs/spas. Where they shall have the protection in accordance with either 680.5(B) or (C) depending on voltage specification of the equipment. It states that any receptacles of 125V through 250V, up to 60 Amps, situated within 20ft (6m) of the containment walls of the specific storable pool/hot tub/spa also needs the specified protection above.

# NEC Article 680.43

This subsection states the specifications for the indoor installations of hot tubs & spas. The ground fault protection part of this subsection, 680.43(A)(2), states that any receptacles of 125V through 250V, up to 60 Amps, situated within 10ft (3m) of the containment wall of the hot tub/spa requires GFCI protection according to 680.5(B) or SPGFCI protection according to 680.5(C), depending on the electrical specifications of the hot tub/spa.

# NEC Article 680.44

This section continues with giving GFCI and SPGFCI protection guidelines for hot tubs & spas. There are 3 sections which include:

A.) This is the “general” section, stating that unless otherwise stated in the next two parts, the spa/hot tub needs to follow section 680.5(B) or (C) for required GFCI or SPGFCI protection according to power specifications if the appliance.
B.) Any of the Listed subcomponents (lights, blowers , pumps, heaters, sanitizers , etc.) involved with a spa/hot tub that is a Listed product (encompassing an integral GFCI in its construction) does not need additional ground fault protection.
C.) this part of subset 680.44 has the guidelines for gas-fired water heaters. It says that any circuit serving a gas-fired hot tub/spa heater operating above the intrinsic safety voltage limit, requires ground fault protection.

# NEC Article 680.58

This subsection dictates the GFCI and SPGFCI protection for fountains. It states that all receptacles of 125V through 250V, up to 60 Amps, situated within 20ft (6m) of a fountain basin shall have GFCI protection correlating with 680.5(B) or SPGFCI protection according to 680.5(C).

# NEC Article 680.59

This subsection dictates the GFCI and SPGFCI protection for non-submersible pump motors. It states that the junction outlets that supply all permanently installed non-submersible pump motors are required to have GFCI protection according to 680.5(B) or SPGFCI protection according to 680.5(C) when applicable.

# What does this Code mean?

There are a lot of different parts to NEC 680 regarding to GFCI and SPGFCI protection, but the bottom line is you are either following code 210.8 for Class A (6mA) GFCI protection, and if there is any question or additional information added follow 680.5(B) for GFCI protection and 680.5(C) for Class C (20mA) SPGFCI protection.

2023 Code Year: NEC 680


![2023 Code Year NEC 590.6](2023-Code-Year-NEC-590.6-display.webp)

NEC Article 590 stipulates the electrical safety measures for temporary power. Learn more about the ground fault protection required at your construction site.

# What is NEC 590?

NEC Article 590 and all of its subsets are in relation to Temporary Installations. This means that it involves the electrical protection provisions for all temporary electrical power and lighting installations. Subset 590.6 (and more specifically 590.6(A)), dives into the mandated GFCI for temporary powered products. This subset, and all of its extensions, include:

# NEC Article 590.6:

This section is the specific destination for Ground-Fault Protection for the personnel working with all temporary wiring installations in a plethora of different working environments (from demolition, construction, remodeling, repair, and maintenance, etc.). The Article also states that it needs to comply with requirements set in 590.6(A) & (B).

# NEC Article 590.6(A)

This section states (specifically for receptacle outlets) for the temporary use power to equipment in the stated locations (from section 590.6) need to comply with the requirements of 590.6(A)(1) through 590.6(A)(3). These sections state, in order:

1.) This part is for the receptacle outlets that are not part of the permanent venue wiring. This including 125VAC, single-phase, up to 30-Amp configured receptacles that are not a part of the fixed wiring of the building /structure, and which are in use by personnel must encompass ground-fault circuit-interrupter (GFCI) protection. On top of this, any required GFCI protection for personnel, listed cord sets/devices incorporating Listed GFCI protection must be of the portable construction type.
2.) This section is for the existing receptacles that are a part of the permanent infrastructure. They will require GFCI protection for personnel for all 125VAC, single-phase, up to 30-Amp receptacle outlets. Just as the previous section, this is accomplished with the use of “portable type” listed cord sets/devices.
3.) The last extension of subset 590.6(A) is concerning receptacles integral to a 15kW or smaller portable generator. Panel integrated 125VAC and 125/250VAC, single-phase, up to 30-Amp receptacle outlets shall provide listed ground-fault circuit-interrupter (GFCI) protection for personnel. This section also goes on to dictate that “if used in a wet/damp location, follow the guidelines from Article 406(A) & (B) (which dictates that they be weather resistant listed, and incorporate hinged doors for increased ingress protection).

# NEC Article 590.6(B)

This section gives fairly the same information, except it is the rules & regulations for “other” (as in other than the mentioned locations from 590.6(A)) receptacle outlets.

# What does this Code mean?

All and all, NEC 590 dictates the standards for electrical protection of temporary power supply operations, which also tie in similarly with OSHA standards in this instance. The section also makes sure to list when and where you need ground fault protection on a job site, which in most cases is everything under 125VAC and 30 Amps needs to have Class A (6mA) GFCI protection.

![2023 Code Year NEC 555](2023-Code-Year-NEC-555-display.webp)

NEC Article 555 states the electrical safety measures for the marine industry. Learn more about the ground fault protection standards of boats, docks, and more.

# What is NEC 555?

NEC Article 555 and all of its subsets have to do with Marinas, Boatyards, Floating Buildings, and Commercial & Noncommercial Docking Facilities. In more depth, this Article has to do with “the installation of wiring and equipment in the areas comprising fixed or floating piers, wharves, docks, floating buildings, and other areas in marinas, boatyards, boat basins, boathouses, yacht clubs, boat condominiums, docking facilities,” and so on relating to electrical protection in/around a boating area. There are two different subsets in NEC Article 555 that have relation to GFCI and ELCI/GFPE (Equipment Leakage Circuit Interrupter/Ground Fault Protection Equipment) protection, and they are as follows:

![Protoype 30 amp mounted](prototype_30amp_mounted_2.webp)

# NEC 555.35

This subsection is for aquatic vessels and the shore power that supplies them (not including floating buildings). It stipulates the Ground-Fault Protection of Equipment (aka a GFPE/ELCI) and Ground-Fault Circuit Interrupter (GFCI) electrical protection products for marine areas in accordance with its 4 different sections, which are:

A.) The first part of this section involves the Feeder circuits of shore power equipment. A GFPE, rated up to (but not exceeding) 100 mA, shall be provided for feeders installed on docking facilities.
B.) the second part of the section deals with the branch circuits and their circuit protection in the defined areas of this Article, which are:

1.) The first part is regarding receptacles providing shore power. These receptacles must be GFPE, and cannot be rated above 30 mA, and are required to be provided for receptacles installed in accordance with 555.33(A) (12in. above the deck surface of the pier).

2.) The second is for “outlets for other than shore power.” This means outlets supplied by branch circuits up to 150 volts to ground and 60 Amps, single phase, & up to 150 volts to ground, up to 100 Amps, three phase, shall be provided with GFCI protection for personnel.

C.) The third part of this subset section is regarding boat hoists. It states that GFCI protection for personnel shall be provided for outlets up to 240 volts that supply a boat hoist installed at docking facilities. GFCI protected receptacles not involved with shore power may also be permitted to supply boat hoists.
D.) The fourth part of this section is pertaining to leakage current measurement devices. If there are four or more receptacles supplying shore power to boats, a Listed leakage current measurement device for use in marina applications needs to be available and used to determine leakage current from each boat that will plug into the specified shore power. It also states that the listing requirement for the leakage current measurement device for use in marina applications will become effective on January 1, 2026.

# NEC 555.53

This other subset pertains solely to Ground-Fault Protection for floating buildings (as part of “Part III” of this Article titled “Floating Buildings”). It states that the main overcurrent protective device that feeds into a floating building needs to have ground-fault protection below 100mA. It also states that Ground-fault (GFCI) protection of each individual branch or feeder circuit can be a sufficient alternative.
This article has a lot of different rules and guidelines from most of the other NEC Articles due to the nature of the areas it is describing (outdoor aquatic areas) and for good measure. It is imperative to follow electrical safety standards to protect yourself and others from electrical shock, but it is even more dire of a need in aquatic environments because electric shock can lead to death from drowning (coined ESD, for electric shock death). This is a very serious matter that has affected a lot of families around the country, and while all NEC guidelines should be followed, this is one of the most important in terms of life and death safety for people encountering electrical appliances.

2023 Code Year: NEC 555


![2023 Code Year NEC 625](2023-Code-Year-NEC-625-display.webp)

NEC Article 625 outlines the safety measures involved in electric vehicle charging. Learn more about what it says specifically about ground fault protection.

# What is NEC 625?

NEC Article 625 and all of its subsets deal with Electric Vehicle Power Transfer Systems, or in simpler terms, anything that involves the charging of an electric vehicle (EV). Everything in this Article relates to the safe practice of charging EVs with Electric Vehicle Supply Equipment (EVSE, also known as an EV charging station or EV charger). It is also very expansive, detailing the mandated procedures for a given EVSE, such as manufacturing specifications (x. cable length), installation methods, rules for different product variations (portable, permanent, wireless charging, etc.), and more. While every part of this Article has merit, we will look at a few subsets that have the most purpose for your safety, which include:

# NEC Article 625.6

This subsection is very straightforward, stating that your charging system needs to be (UL) Listed. This, in more detail, means that the charging system has passed the rigorous safety testing requirements made and carried out by Underwriters Laboratory.

# NEC Article 625.42

This subsection deals with the rating (as in electrical amperage rating) of the charging system. It states that the charging system needs to have an acceptable supply of electricity to meet the demands of the charging system. What that means is the breaker supplying the electricity to the charging system needs to be rated above the charging system’s capacity (if you have a 32-amp charging station then you need it to be supplied by a 40-amp breaker). There are 2 ways to get around this however, which include:

A. If there is an energy management system (EMS) involved that can supply load management to the EVSE. The EMS can be for either 1 or multiple charging stations, but it needs to be set to have the maximum load allowed be in accordance with the feeder (breaker) of the equipment. Most EMS systems are usually for designed commercial & industrial EV charging applications that involve numerous vehicles.

B. The other way to get past is by having a charging system with an adjustable amperage setting. This will allow a user to set the charging station to an amperage setting lower than the breaker's allowance of electricity, therefore operating at an acceptable current level.
NEC Article 625.54: This part of the Code simply states that there needs to be Ground Fault Circuit Interrupter (GFCI) protection involved in every charging system. This is also (partially) explained in more detail in two other subsections. In 625.22 it states that a Listed “personnel protection system” is needed, which implies GFCI protection but can include more in the system. Also, in 625.60(D) it states that the charging system needs to have a visible indication and reset options on the product (which implies GFCI test & reset capabilities).

# What does this Code mean?

This NEC section specifies the safety measures needed in the charging equipment for an electric vehicle in extensive detail. To meet all of these stringent requirements the NEC states that any EVSE used should be UL Listed so that it meets the guided standards of protecting the user charging the vehicle from harm in any environment. Also note, UL has different testing thresholds for EV chargers for indoor and outdoor use, so make sure to check what your EVSE is Listed for specifically to make sure you don’t use unsafe charging equipment in the harsh outdoor elements.

![2023 Code Year NEC 410.184](2023-Code-Year-NEC-410.184-display.webp)

NEC Article 410 outlines the electrical safety standards for lighting. Learn more about the ground fault protection needs for indoor horticulture lighting.

# What is NEC 410?

NEC Article 410 deals with the location, electrical protection, and inspection requirements involved with luminaires, lamp holders, and lamps. This section is very large and involves guidelines to lighting structures in a variety of commercial and industrial industries. There is one that has a very specific guidance involving ground fault protection, which is:

# NEC Article 410.184:

NEC Article 410.184 is the Ground Fault Circuit Interruption section of NEC article 410, which relates to horticulture lighting. Just as many subsets of NEC guidelines, it is very to the point, stating that “for any horticultural use employing flexible cords with one or more conductors shall be supplied by lighting outlets protected by a (UL) Listed ground-fault circuit interrupter”. This means that in larger growing operations, the lighting fixtures must be protected by a UL recognized GFCI. Also, with the 2023 update language, it includes Listed special purpose ground-fault circuit-interrupter (SPGFCI) protection for circuits exceeding 150V, as this is common for the size of lighting installations in this industry.

# What does this Code mean?

Just like it is stated above, lighting structures in horticulture growing settings need UL Listed ground fault protection. Now however, the NEC has added more to accommodate the large lighting structures involved in this specific industry, so circuits with over 150V can now have SPGFCI protection, which is a higher trip threshold (Class C 20mA) than normal Class A GFCI protection (6mA).

2023 Code Year: NEC 525.23


Below are maps of the United States depicting what National Electrical Code year each state follows and when they will update their Code year as of 3/1/24.

# NEC Code Adoption by State as of 3/1/24

NEC (National Electrical Code) is fickle in the fact that although it comes out with a new Code every 3 years (including this year with their NEC Handbook 2023 edition) it takes time for each state to officially adopt a given Code year. Some states work to stay current (such as Massachusetts which has 2020 Code and is working on updating to 2023) while some states lag behind (Kansas has followed 2008 Code since 2008) and others leave it up to their counties or cities to decide what they follow (such as Arizona). There are also some odd stipulations, such as the state of New York following 2017 Code, but New York City follows 2008 Code. Here is a map of each state and which NEC Code year they follow as of 3/1/24.

# NEC Code Update by State as of 3/1/24

Another thing to keep in mind with NEC Code adoption is that it is an ongoing process. Not all states adopt new Codes right away (such as North Carolina having no plans to update their 2020 NEC currently), and some states can jump certain years altogether (Indiana is currently in the process of updating to 2023 Code from 2008 Code). Here is a map of what each state is planning on update wise currently.

# Conclusion

As stated before, this map is ever changing. As of today, 3/1/24, this is where each state lies with NEC updates, but we at NSS will be sure to update this map when any states change their Code year in the coming future.
