NEC 2023 Electric Code Changes: Most Important Updates

The National Electric Code helps keep our homes, workplaces, and public spaces safe from electrical hazards. It is updated often to adapt to technological advancements and to ensure the utmost protection for people and property.

In this comprehensive guide, we will delve into the most significant updates in the NEC 2023 edition, shedding light (no pun intended) on the changes that will shape the way electricians work in order to maintain a safe and compliant environment.

What Is the NEC?

The National Electrical Code (NEC) is a standard for electrical installations in the United States. It is also known as NFPA 70 because it is published by the National Fire Protection Association. The NEC code book sets the safety guidelines and requirements for electrical wiring, equipment, and systems to protect people from electrical hazards.

How Often Is the NEC Updated?

First issued in 1897, the NEC is updated every three years to incorporate new technologies and safety measures. This regular updating ensures that the code remains relevant and reflects the most current practices and requirements in the field of electrical installations. The NEC was last updated in 2023.

Is the 2023 NEC Out Yet?

Yes, the 2023 NEC is currently available to the public. The NEC release date usually falls during the Autumn season. The NFPA Standards Council issued NEC 2023 on August 12, 2022, with an effective date of September 1 for federal, state, county, and municipal governments.

What Are the Changes in the NEC for 2023?

From new GFCI requirements to outdoor outlets, several updates were made to the 2023 NEC. Let’s go over some of the biggest changes you need to be aware of:

GFCI Updates

Many changes related to GFCI protection were updated in the 2023 National Electrical Code. Notably, the term “ground fault circuit interrupter” is replaced with “listed Class A GFCI.” Section 210.8(A)(6) expands GFCI protection to all plug-and-cord-connected appliances in kitchens, removing distance limitations between kitchen sinks and 125-240V receptacles. Exception 4 notes that bathroom exhaust fan internal receptacles don’t need GFCI protection unless the manufacturer specifies. Section 210.8(B) mandates GFCI-protected receptacles in areas with sinks and provisions for cooking. Section 210.8(D) broadens GFCI protection to various outlets, including electric ranges and clothes dryers.

In outdoor settings, Section 210.8(F) requires GFCI protection for specific outlets in garages, accessory buildings, and boathouses. Section 410.184 mandates GFCI protection for horticultural lighting with separable connectors. Section 680.22 calls for GFCI protection for receptacles rated 60A or less within 20 feet of a swimming pool wall. Additionally, equipment installed 5-10 feet horizontally from the inside walls of a pool must have GFCI or SPGFCI protection if it includes luminaires, lighting outlets, or ceiling fans. These updates enhance electrical safety in various settings and applications.

Additional Changes

Some other notable updates made in the 2023 NEC include:

Section 110.26(A)(4): Doors for electrical equipment in narrow pathways must not block escape routes. Imagine an electrical room in a building. If there’s an emergency, the doors to this room shouldn’t hinder people from being able to get out quickly.
Section 110.3: Cybersecurity is now included in electrical equipment safety standards. Just like you secure your computer or phone, electrical systems must be protected from cyber threats to prevent unauthorized access or tampering.
Section 210.12(D): AFCI protection is extended to sleeping quarters in fire and police stations. This change enhances safety by preventing electrical fires in these essential places.
Section 210.17: This change requires specific electrical circuits in guest rooms with cooking facilities in hotels and motels. This can help give tourists extra piece of mind while they’re away on vacation.
Section 215.15: Protective barriers must be used to prevent exposure to electrical busbars during maintenance. These covers can help reduce injuries from workers accidentally coming into contact with live electrical parts.
Section 125.18: Surge protection devices are now required in various settings, including hotels and nursing homes. These surge protectors can help safeguard against voltage spikes in establishments like these with a high number of residents.
Section 220.70: Digital energy management systems can now control maximum current use. Similar to a smart thermostat regulating your home’s temperature, this helps manage electrical loads efficiently.
Section 406.12: Tamper-resistant receptacles are mandated in places like childcare facilities and motel rooms. These are outlets designed to prevent children from inserting objects and getting electrical shocks.
Section 555.4: Service equipment for marinas should have specific clearance from the water and a set height above the electrical datum plane. This ensures safety around water and electrical systems on docks.
Section 555.15: While we’re on the topic of safety around water, this section specifies that damaged equipment at docking facilities must be identified, documented, and repaired according to code. This is similar to ensuring damaged appliances in your home are fixed safely.
Section 625.50: Electric vehicle (EV) supply equipment now requires individual branch circuits for high-power charging. Just like appliances, electric vehicles now get dedicated circuits for charging.
Section 625.49: Electric vehicle power export equipment can be part of an interconnected power system for backup. It’s like having a power backup system for your home but for your EV.
Section 680.54(C): Defines the boundary of a splash pad for equipotential bonding purposes. This clarification is important to ensure proper bonding for safety and compliance.
Section 700.11: Voltage requirements for emergency lighting systems are established, ensuring reliable emergency lighting during power outages. This can come in handy during a blackout.

What Are the Emergency Disconnect Requirements for 2023 NEC?

An emergency disconnect is a switch that will shut off the power coming from the utility power service to the entire house in case of an emergency. Some changes in the 2023 NEC regarding emergency disconnects include:

Section 225.41: Requires that feeders supplied to one and two-family dwelling units have outside emergency disconnects that are clearly labeled. This allows first responders to disconnect power on the outside of a dwelling in case of emergency.
Section 440.11: Requires that, in residential spaces where unqualified persons can readily access the means to disconnect an air conditioner, the disconnect enclosure or the hinged door that exposes energized parts must be capable of being locked or require a tool to be opened.
