Prepare for the Texas Residential Wireman Electrician examination with a highlighted and tabbed 2026 National Electrical Code designed to support organized study, faster code navigation, and more efficient open-book exam preparation. Texas adopted the 2026 National Electrical Code effective September 1, 2026, and current Texas electrician examinations use the 2026 NEC as the technical examination reference.
The Texas Residential Wireman license is administered by the Texas Department of Licensing and Regulation. A Residential Wireman is licensed to perform electrical installations in single-family and multifamily dwellings not exceeding four stories. Candidates must meet the applicable education or experience requirements, receive examination authorization from TDLR, and pass the state examination administered through PSI.
This package includes the National Electrical Code, NEC, 2026 prepared with highlighting and tabs. The prepared codebook can help candidates organize frequently studied sections and build familiarity with the NEC articles, tables, definitions, exceptions, and cross-references that apply to residential electrical installations.
The Texas Residential Wireman examination covers services, feeders, branch circuits, conductor sizing, grounding and bonding, wiring methods, electrical equipment, motors, generators, control devices, special installations, renewable-energy technologies, calculations, theory, and electrical plans.
Residential electrical work reaches across many sections of the NEC. Candidates should be prepared for dwelling service calculations, required branch circuits, receptacle and outlet requirements, GFCI and AFCI protection, grounding electrode systems, conductor ampacity, wiring methods, appliances, heating and cooling equipment, pools, photovoltaic systems, and electric vehicle charging equipment.
A highlighted and tabbed NEC can make study more efficient by helping candidates develop an organized approach to the code. Candidates should still practice repeatedly with the book so they learn the general location of frequently tested requirements and do not depend on a lengthy search for every examination question.
Please allow up to 15 business days for tabbed and highlighted book package orders.
The Texas Residential Wireman Electrician examination is administered through PSI after the applicant has been approved to test by the Texas Department of Licensing and Regulation.
The current examination content outline distributes the 80 scored items across the following areas:
Electrical Services, Service Equipment, and Separately Derived Systems is the largest current examination category with 16 scored items. Branch Circuit Calculations and Conductors follows with 14 items, while Electrical Equipment and Devices accounts for 12 items.
Unless specifically stated otherwise in an examination question, conductors are treated as copper.
The Texas Residential Wireman Electrician examination is an open book test.
The current examination reference is the National Electrical Code, NEC, 2026 Edition. Candidates are responsible for bringing their own acceptable NEC book to the examination site.
TDLR permits soft-bound editions of the NEC for electrician examinations. Loose-leaf, spiral-bound, and ring-bound copies are not permitted in the examination room.
A highlighted and tabbed NEC can be especially useful during preparation because residential examination questions may require movement between several different articles. A single dwelling installation question could involve a branch-circuit requirement, conductor ampacity, grounding, overcurrent protection, equipment installation, and a special residential provision.
Candidates should use the prepared NEC during timed study sessions and practice moving directly to frequently used residential sections. Developing familiarity with the organization of the book can reduce unnecessary searching and leave more time for calculations and code application.
A Texas Residential Wireman is licensed to perform electrical installations in single-family and multifamily dwellings not exceeding four stories.
Applicants may qualify by providing proof of completion of an approved career and technology education program or by documenting at least 4,000 hours of on-the-job electrical training under the supervision of a Texas-licensed Master Electrician or Residential Wireman.
Applicants using the experience pathway must obtain verification from each Master Electrician or Residential Wireman who supervised the qualifying work. TDLR may contact the individuals involved to verify submitted experience.
Completion of an approved career and technology education program does not eliminate the examination requirement. Candidates using that pathway must still take and pass the Texas Residential Wireman examination.
The Residential Wireman credential has a more limited scope than the general Texas Journeyman Electrician license. The license is focused specifically on electrical installations in qualifying single-family and multifamily dwellings.
Residential Wireman licenses are valid for one year from the date of issuance and must be renewed annually.
Texas adopted the 2026 National Electrical Code effective September 1, 2026. The updated Texas electrician examinations were re-referenced to the 2026 NEC for the current testing cycle.
The highlighting and tabs are designed to support organized preparation and more efficient NEC navigation. Candidates should use the prepared codebook regularly so important residential articles and tables become familiar before the examination.
Please allow up to 15 business days for tabbed and highlighted book package orders.
