State Requirements

Texas Maintenance Electricians are licensed to perform electrical maintenance work while working under the general supervision of a Master Electrician.

Applicants must document at least 8,000 hours of on-the-job training under the supervision of a Texas-licensed Master Electrician or Maintenance Electrician.

The experience requirement reflects the practical nature of maintenance electrical work. Candidates are expected to have substantial exposure to existing electrical systems, conductors, overcurrent protection, wiring methods, equipment, motors, controls, grounding and bonding, and other electrical installations encountered during maintenance and repair.

After TDLR receives and verifies the completed application, the applicant receives authorization to take the licensing examination through PSI.

The Maintenance Electrician license is different from a Texas Journeyman Electrician license. The Maintenance Electrician credential is specifically directed toward electrical maintenance work and does not create the same general scope associated with the Journeyman Electrician credential.

Texas electrician licenses are valid for one year from the date of issuance and must be renewed annually. License holders must satisfy the renewal requirements that apply to their credential.

Texas adopted the 2026 National Electrical Code effective September 1, 2026. The current Texas electrician examinations are referenced to the 2026 NEC.
