Open Book Test

The Texas Residential Wireman examination is an open book test.

The technical reference used for the current examination is the National Electrical Code, NEC, 2026 Edition. Candidates should become comfortable navigating the NEC before testing so they can locate applicable requirements efficiently.

Acceptable soft-bound NEC editions may be used. Loose-leaf, spiral-bound, and ring-bound copies are not permitted in the examination room. The NEC Handbook is not permitted as the examination reference.

The NEC may contain permitted highlighting, underlining, notes prepared before testing, and compliant permanent NEC index tabs. Candidates may not add new notes, highlighting, underlining, indexing, or other markings during the examination session.

The rental NEC included with The 1 Package is highlighted and tabbed for organized preparation and reference navigation. Candidates can use the same prepared codebook throughout the 1 year of course access to reinforce familiarity with major residential electrical provisions.

An open-book examination still requires strong preparation. Candidates should be able to recognize whether a question involves a service, feeder, branch circuit, wiring method, dwelling load calculation, equipment requirement, grounding provision, motor, special installation, or renewable energy system before searching the code.

State Requirements

The Texas Residential Wireman license is an individual electrician credential designed for residential electrical work within its defined scope. A Residential Wireman may perform qualifying electrical installations in single-family and multifamily dwellings not exceeding four stories.

Under the standard experience pathway, applicants must document at least 4,000 hours of qualifying on-the-job electrical training. Texas also provides an approved career and technical education pathway that may apply to qualifying candidates.

The Residential Wireman license is more limited in scope than the Texas Journeyman Electrician license. Candidates should understand that earning the Residential Wireman credential does not automatically provide authority to perform every type of commercial, industrial, or unrestricted electrical installation.

The examination reflects the residential focus of the credential through its strong emphasis on services, branch circuits, wiring methods, equipment, conductors, and other subjects commonly encountered in dwelling electrical systems.

The Residential Wireman license is an individual credential. Operating an electrical contracting business involves separate contractor licensing and compliance considerations beyond holding the individual Residential Wireman license.

The business setup portion of The 1 Package supports customers with Business Formation, EIN Filing with the IRS, and Contractor Compliance Guidance as they organize a formal business structure.

Texas electrician licenses are subject to annual renewal and applicable continuing education requirements.

The 2026 National Electrical Code is the current technical reference for the Texas Residential Wireman examination.
