Washington A-Nonresidential Lighting Maintenance & Lighting Retrofit Master Electrician Book Package

Prepare for the Washington Nonresidential Lighting Maintenance & Lighting Retrofit Master Electrician examination with a focused reference package built around the electrical code, Washington electrical law, and state administrative rules used for the 07A Nonresidential Lighting Maintenance & Lighting Retrofit specialty. This package includes the Revised Code of Washington (RCW) Chapter 19.28, Washington Administrative Code (WAC) Chapter 296-46B, and the National Electrical Code, NEC, 2020 Edition.

Washington officially identifies this specialty as 07A Nonresidential Lighting Maintenance & Lighting Retrofit. The classification focuses on work performed within the housings of existing nonresidential luminaires for repair, service, maintenance, and installation of qualifying energy-efficiency lighting retrofit upgrades.

The Washington 07A Master Electrician examination tests National Electrical Code knowledge, electrical theory, and Washington electrical laws and rules. Candidates should understand lighting equipment, overcurrent protection, grounding and bonding, general electrical requirements, hazardous-location considerations, and the Washington regulations that define exactly what work may and may not be performed under the 07A specialty.

Washington electrical examinations are open book. Approved reference materials may be used during testing, making efficient reference navigation an important part of preparation. Candidates should learn how to determine whether a question belongs in the NEC, RCW Chapter 19.28, or WAC Chapter 296-46B and locate the applicable requirement efficiently.

The 07A specialty is intentionally narrow. It includes repair and maintenance work within existing nonresidential luminaires and defined lighting retrofit activities, but it does not authorize installation of new luminaires or branch circuits, relocation of existing luminaires, or alteration of existing branch circuits. Understanding that boundary is an important part of both the examination and work performed under the certification.

This package combines the three core references needed for structured preparation. The NEC provides national technical electrical requirements, RCW Chapter 19.28 establishes Washington electrical law, and WAC Chapter 296-46B defines specialty scope and contains detailed requirements governing certification, examinations, supervision, contractors, permits, inspections, and electrical installations.

  1. Obtain the 07A specialty electrician certificate. The Master Electrician pathway begins with certification in the corresponding Nonresidential Lighting Maintenance & Lighting Retrofit specialty.
  2. Hold the 07A certificate for at least two years. Washington requires specialty Master Electrician candidates to have been certified in the applicable specialty for at least two years.
  3. Apply for the Master Electrician examination. Submit the applicable examination application to Washington Labor & Industries.
  4. Receive examination eligibility approval. Master Electrician candidates must receive approval before scheduling the examination through PSI.
  5. Prepare for NEC & Theory. Study the 2020 NEC with emphasis on lighting equipment, grounding and bonding, overcurrent protection, hazardous locations, and electrical theory.
  6. Prepare for Washington Codes. Review RCW Chapter 19.28 and WAC Chapter 296-46B, including the 07A scope and Master Electrician responsibilities.
  7. Schedule the examination with PSI. Use the eligibility information provided after L&I approval.
  8. Pass both required sections. Washington requires a score of at least 70% on each examination section.
  9. Complete the certification process. Follow Washington Labor & Industries requirements for issuance of the 07A specialty Master Electrician certificate.

State Requirements

Washington identifies Nonresidential Lighting Maintenance & Lighting Retrofit as specialty classification 07A. A specialty Master Electrician applicant must have held the corresponding specialty electrician certificate for at least two years before qualifying for the Master examination.

The underlying 07A Electrician pathway requires 2,000 hours of qualifying work experience for full certification. A trainee may become eligible to take the 07A specialty examination after completing at least 720 hours of qualifying supervised experience.

Until the specialty examination is successfully completed, the trainee must work under 100 percent supervision by an electrician who is appropriately certified for the work being performed or by a general journey level electrician.

After passing the specialty examination, a qualifying trainee may work under the modified-supervision provisions while completing the balance of the 2,000 hours required for full certification, subject to Washington requirements.

The 07A specialty is limited to working within the housing of existing nonresidential luminaires for repair, service, maintenance, and installation of qualifying energy-efficiency lighting retrofit upgrades.

The specialty includes the replacement of ballasts and sockets and installation of listed lighting retrofit reflectors and kits. Work is generally limited to the luminaire body.

Remote-located ballasts are an exception to the general luminaire-body limitation. Washington allows remote ballasts to be replaced or retrofitted with approved products within the 07A specialty.

The classification does not include installation of new luminaires or new branch circuits. It also does not permit moving or relocating existing luminaires or altering existing branch circuits.

These limitations are important for Master Electricians because a specialty master may work with the tools of the trade within the scope of the certification and may also be assigned to a corresponding electrical contractor. Work performed under the contractor must remain within the legal scope of the specialty.

A Washington Master Electrician may serve as the designated master for an electrical contractor when the applicable assignment and contractor-classification requirements are satisfied. In that role, the Master Electrician helps ensure that the contractor's electrical work complies with Washington electrical laws and rules.

Washington Master Electricians are also subject to certification-renewal and continuing-education requirements. The continuing-education cycle includes approved NEC update education, Washington RCW/WAC education, and additional approved coursework.

Test Information and Study Materials

Electrical Equipment: This is the largest technical category on the 07A Master Electrician outline. Review requirements affecting luminaires, lampholders, lighting equipment, flexible cords and cables, equipment connections, transformers used with lighting equipment, and related electrical components.

Grounding and Bonding: Study equipment grounding conductors, bonding of metal luminaires and enclosures, grounding continuity, grounding methods, and requirements affecting replacement or retrofit work.

Overcurrent Protection: Review breakers, fuses, conductor protection, equipment ratings, branch-circuit protection, and the relationship between existing circuits and lighting equipment.

General Requirements: Review NEC definitions, equipment approval, listing and labeling concepts, installation and use requirements, working space, interrupting ratings, and other general provisions that can affect lighting maintenance.

Hazardous Locations: The examination includes hazardous-location content. Candidates should understand basic classified-location requirements and recognize when specialty lighting work may involve additional limitations.

General Trade Knowledge and Theory: Practice voltage, current, resistance, power, Ohm's law, basic lighting calculations, series and parallel circuit concepts, and troubleshooting principles related to lighting equipment.

Washington 07A Scope: Study the boundary between permitted luminaire maintenance and prohibited new electrical installation. Know that the specialty permits work within existing luminaire housings but does not authorize new luminaires, new branch circuits, relocation of luminaires, or alteration of branch circuits.

Lighting Retrofit Work: Review listed retrofit products, ballast replacement, sockets, retrofit reflectors and kits, and the distinction between approved retrofit work and modifications that exceed the specialty scope.

Washington Master Electrician Rules: Review eligibility, contractor assignment, Master Electrician responsibilities, certification, renewals, examinations, permits, and inspections.

A productive preparation method is to separate practice questions by reference source. Technical lighting questions are generally answered through the NEC, while questions involving the 07A work scope, supervision, experience, or certification should direct candidates to RCW Chapter 19.28 or WAC Chapter 296-46B.

How 1 Exam Prep Helps You Reach Your Goal

1 Exam Prep helps Washington Nonresidential Lighting Maintenance & Lighting Retrofit Master Electrician candidates organize their preparation around the three core references included in this package: the 2020 National Electrical Code, RCW Chapter 19.28, and WAC Chapter 296-46B.

The package supports trade-focused review of electrical equipment, grounding and bonding, overcurrent protection, lighting maintenance, lighting retrofits, electrical theory, specialty scope, and Washington electrical laws and rules.

1 Exam Prep encourages practice-oriented preparation for the open-book examination. Candidates can strengthen reference-navigation skills by reading each question, identifying the likely source, locating the controlling requirement, and applying the code or rule efficiently.

Lighting technicians often bring practical experience with ballast replacement, lamp and socket service, luminaire troubleshooting, and retrofit products. Structured preparation helps connect that hands-on knowledge with the exact NEC and Washington requirements that govern the specialty.

Washington-specific study is especially important for 07A because the specialty has a narrow and clearly defined scope. Master candidates should know not only how lighting equipment is serviced but also when a proposed activity crosses into work requiring a broader electrical certification.

The goal is to combine field experience with organized study, stronger code familiarity, Washington regulatory knowledge, effective reference navigation, and confidence-building preparation. This Washington A-Nonresidential Lighting Maintenance & Lighting Retrofit Master Electrician Book Package provides the core materials needed to support that study process.
