Texas Master Electrical Contractor - Highlighted and Tabbed Book Package

Prepare for the Texas Master Electrician examination with a highlighted and tabbed 2026 National Electrical Code designed to make code navigation more efficient during study and exam preparation. Texas adopted the 2026 National Electrical Code as the state electrical code effective September 1, 2026, and current Texas electrician examinations use the 2026 NEC as the examination reference.

This package is built for experienced electricians working toward the Texas Master Electrician credential and for professionals whose long-term goal includes qualifying an electrical contracting business. Texas distinguishes between the individual Master Electrician license and the business-level Electrical Contractor license. An Electrical Contractor must employ a licensed Master Electrician who serves as the Master Electrician of Record, although the Master Electrician may also own the contracting business.

The included National Electrical Code, NEC, 2026 is highlighted and tabbed to support faster study and more organized navigation. Important sections can be easier to locate when reviewing services, feeders, branch circuits, grounding and bonding, motors, generators, wiring methods, conductor sizing, special occupancies, special equipment, renewable-energy systems, and electrical calculations.

The Texas Master Electrician examination is administered through PSI for the Texas Department of Licensing and Regulation. The examination is divided into two separately timed portions: an NEC Knowledge Portion and a Calculations Portion. Candidates must earn at least 70% on each portion.

Master-level electrical testing requires candidates to apply NEC requirements across a wide range of installations rather than relying on memorization alone. Candidates should understand how code articles interact, how exceptions affect general rules, and how tables, adjustment factors, demand factors, ampacity requirements, motor rules, grounding provisions, and special installation requirements apply to practical electrical problems.

Please allow up to 15 business days for tabbed and highlighted book package orders. The additional processing time allows the physical NEC book to be prepared before the order is completed.

Open Book Test

The Texas Master Electrician examination is an open book test. The current examination reference is the National Electrical Code, 2026 Edition.

Candidates are responsible for bringing their own NEC book to the examination center. Texas permits a soft-bound edition of the NEC. Loose-leaf, spiral-bound, and ring-bound NEC copies are not permitted, and the NEC Handbook is not an approved examination-room substitute for the codebook.

The NEC may be highlighted and underlined before the examination session and may contain notes prepared before testing. Current examination rules also permit permanent NEC index tabs manufactured or provided for use with the NEC book. Candidates may not add highlighting, underlining, notes, indexing, or other markings during the examination itself.

A highlighted and tabbed NEC can support study by making commonly referenced subjects easier to locate. Master Electrician candidates should become comfortable moving quickly among Articles 100, 110, 210, 215, 220, 230, 240, 250, 300, 310, 314, 430, and the NEC chapters covering special occupancies, special equipment, and special conditions.

State Requirements

Texas Master Electrician applicants must have held a Journeyman Electrician license for at least two years and must document at least 12,000 hours of on-the-job electrical training under the supervision of a Texas-licensed Master Electrician.

The Texas Master Electrician credential authorizes electrical work involving the installation, maintenance, or extension of electrical wiring systems and associated apparatus and equipment within the scope established by state law.

The Master Electrician license should not be confused with the Texas Electrical Contractor license. The Master Electrician license is an individual credential. The Electrical Contractor license applies to the contracting business.

A Texas Electrical Contractor must employ a licensed Master Electrician as the company's Master Electrician of Record. The Master Electrician may also own the business. A Master Electrician is generally assigned to only one Electrical Contractor unless the Master Electrician owns more than 50% of the electrical contracting business.

Texas adopted the 2026 National Electrical Code effective September 1, 2026, with a limited state exception relating to certain GFCI requirements for outdoor outlets serving HVAC equipment.
