NEC 2023 Code Changes: What Every Texas Electrician Needs to Know

The 2023 National Electrical Code (NEC), formally known as NFPA 70, 2023 Edition, was adopted by Texas effective September 1, 2023. All non-exempt electrical work started on or after that date must comply with the 2023 edition. This is the code tested on TDLR licensing exams through August 31, 2026 and the edition covered in continuing education courses.

Texas adopts a new edition of the NEC roughly every three years, following NFPA's update cycle. The 2023 NEC replaced the 2020 edition; on July 28, 2026 the Texas Commission of Licensing and Regulation adopted the 2026 NEC, effective September 1, 2026. Understanding the current code is essential not just for daily work but also for your annual Texas electrical continuing education requirement.

The 2023 edition includes hundreds of revisions, but this guide focuses on the changes with the greatest practical impact for Texas electricians. These are the updates you will encounter on job sites, in inspections, and in your CE coursework.

The 2023 NEC made some of the most significant expansions to ground-fault circuit interrupter (GFCI) requirements in the code's history. Prior editions used fragmented, location-based language. The 2023 edition consolidates and broadens GFCI rules under a clearer framework.

Key GFCI changes:

• Voltage and amperage expansion: GFCI protection now covers circuits rated up to 150 volts to ground and up to 50 amperes in dwelling units. Previous editions capped coverage at 120 volts and 20 amps in many locations.
• Kitchen and laundry areas: 240-volt appliance circuits in kitchens and laundry rooms (such as ranges and dryers) now require GFCI protection in dwelling units.
• Outdoor outlets: The requirement for GFCI-protected outdoor outlets has been expanded and clarified. All outdoor outlets in dwelling units now require GFCI protection regardless of the receptacle type.
• Crawl spaces and basements: Additional locations now mandate GFCI protection at higher voltage and amperage thresholds.

These changes directly affect residential and commercial work throughout Texas. Inspectors are enforcing the expanded requirements on all new work started after September 1, 2023. Our 4-hour CE course at OnlineTexasCE.com covers these GFCI changes in detail — $22.95, no final exam.

The 2023 NEC also expanded arc-fault circuit interrupter (AFCI) requirements and introduced mandatory surge protection for dwelling units.

AFCI changes:

• Dormitory units: AFCI protection is now required for all 120-volt, 15- and 20-ampere branch circuits in dormitory unit bedrooms, living rooms, hallways, closets, and similar areas. This brings dormitories in line with existing dwelling unit requirements.
• Patient care areas: Revised language clarifies AFCI requirements in healthcare settings where they do not interfere with critical equipment operation.

Surge protection (Article 242):

• Type 1 or Type 2 surge-protective device (SPD) is now required at the service equipment of all dwelling units. This was optional in the 2020 NEC — it is now mandatory.
• The requirement recognizes the increasing vulnerability of modern homes to surge damage, given the proliferation of sensitive electronics, smart home systems, and EVSE equipment.
• SPDs must comply with UL 1449 and be listed for the application.

For Texas electricians, the surge protection mandate creates a new installation requirement on virtually every residential service upgrade or new construction project. Familiarize yourself with Article 242 and the listed SPD options available from major manufacturers.

With EV adoption growing rapidly in Texas, the 2023 NEC made substantial updates to electric vehicle supply equipment (EVSE) and energy storage system (ESS) requirements.

Article 625 — EVSE changes:

• Complete reorganization: Article 625 was restructured for clarity. Provisions are now organized by installation type rather than by technical requirement, making the article easier to navigate.
• Load management systems: New provisions allow the use of electric vehicle power management systems (EVPMS) for load management, enabling multiple EVSE outlets to share available capacity without requiring service upgrades. This is significant for multi-unit dwellings and commercial parking structures.
• Bidirectional charging: Recognizes vehicle-to-home and vehicle-to-grid capabilities. Bidirectional EVSE must comply with both Article 625 and Article 705 (interconnected electric power production sources).
• Outdoor EVSE: Updated requirements for outdoor-rated equipment, wiring methods, and disconnecting means.

Article 706 — Energy Storage Systems:

• Expanded scope: Now covers battery storage, flywheel, and other energy storage technologies beyond lithium-ion.
• Disconnecting means: New requirements for accessible disconnecting means for ESS installations.
• Signage and labeling: Enhanced marking requirements for first responders and service personnel.

Texas legislation (SB 1252, effective September 2025) further requires that all residential energy backup system work be performed by licensed electricians. These NEC provisions and state law changes create growing demand for Texas electricians trained in ESS installation. For more on SB 1252, see our electrician CE requirements page.

Article 250 (Grounding and Bonding) is one of the most frequently revised sections of the NEC. The 2023 edition includes several practical updates:

• Equipment grounding conductor sizing: Updated tables and requirements for sizing equipment grounding conductors in certain installations, particularly for larger feeders and services.
• Bonding of communications systems: Clarified bonding requirements for communications raceways and cables, coordinating with Article 800.
• Grounding electrode conductor protection: New provisions for protecting grounding electrode conductors from physical damage in exposed locations.

Wiring methods and general updates:

• Reconditioned equipment: New requirements in Article 110 for marking and listing of reconditioned electrical equipment. Reconditioned equipment must be marked with the name of the reconditioning facility and the date of reconditioning.
• Emergency and standby systems: Updated requirements in Articles 700, 701, and 702 for energy storage as an alternative or supplement to generator-based emergency power.
• Selective coordination: Revised language clarifying selective coordination requirements for emergency and legally required standby systems.

These changes may seem incremental individually, but collectively they reflect a modernizing code that keeps pace with new technologies, safety data, and installation practices. Every Texas electrician should review these updates as part of their annual CE.

Here is a side-by-side comparison of the most impactful NEC 2023 code changes versus the previous 2020 edition:

Topic	NEC 2020	NEC 2023
GFCI in dwelling units	120V, 20A in specific locations	Up to 150V to ground, 50A in dwelling units
Surge protection (dwelling)	Recommended, not required	Mandatory Type 1 or Type 2 SPD at service
AFCI in dormitories	Not required	Required for 120V, 15/20A branch circuits
EVSE load management	Limited provisions	EVPMS allowed; Article 625 reorganized
Bidirectional EV charging	Not specifically addressed	Recognized with Article 705 coordination
Energy storage (Article 706)	Limited scope	Expanded to cover multiple ESS technologies
Reconditioned equipment	Not specifically addressed	Marking and listing requirements added
Surge protection for ESS	Limited	Enhanced requirements per Article 706

This table covers the headline changes. The full 2023 NEC includes hundreds of additional revisions to individual articles. Your annual 4-hour CE course is designed to cover the changes most relevant to your daily work as a Texas electrician.

TDLR requires covered individual electrician license holders to complete 4 hours of continuing education annually, and those hours must cover the NEC, Texas law and rules, and electrical safety (NFPA 70E). TDLR does not prescribe the hours-per-topic split — in our approved course outline, the NEC is the primary content area at roughly 3 of the 4 hours, with about 1 hour on Texas electrician law (Occupations Code Chapter 1305), administrative rules (16 TAC Chapter 73), and electrical safety (NFPA 70E).

Here is how the CE requirement breaks down by license type and renewal fee:

License Type	CE Hours	Renewal Fee	Renewal Cycle
Master Electrician	4 hours	$45	Annual
Journeyman Electrician	4 hours	$30	Annual
Journeyman Industrial	4 hours	$30	Annual
Journeyman Lineman	4 hours	$30	Annual
Residential Wireman	4 hours	$20	Annual
Maintenance Electrician	4 hours	$20	Annual
Apprentice Electrician	4 hours (or apprenticeship enrollment)	$20	Annual
Master Sign Electrician	4 hours	$45	Annual
Journeyman Sign Electrician	4 hours	$30	Annual

If you hold multiple covered license types, you only need 4 total hours — not 4 per license. Apprentice electricians and apprentice sign electricians may satisfy the renewal condition through enrollment in a TDLR-registered apprenticeship training program instead of the 4 CE hours. Electrical and sign contractor licenses and residential appliance installers have no CE requirement, but the master electrician of record for a contracting company must maintain their personal CE.

The NEC updates on a 3-year cycle. Texas applies the 2023 NEC through August 31, 2026; on July 28, 2026 the Texas Commission of Licensing and Regulation adopted the 2026 NEC, effective September 1, 2026, keeping Texas's amendment to 210.8(F) (no GFCI required for outlets supplying listed outdoor dwelling-unit HVAC equipment). The Examination Review Committee began re-referencing electrician exam items to the 2026 NEC Code Book in November 2025.

What this means for you:

• If your license renews before September 1, 2026: Your CE will cover the 2023 NEC (the edition in force through August 31, 2026).
• If your license renews after the 2026 NEC takes effect: CE providers will update their course content to cover the 2026 NEC changes.
• Exam takers: Licensing exams are scheduled to shift to the 2026 NEC on September 1, 2026. If you are studying for a master or journeyman exam, plan your study timeline accordingly.
