What Is Washington Specialty 07A?

Washington defines 07A as Nonresidential Lighting Maintenance and Lighting Retrofit. The specialty is limited to work within the housing of existing nonresidential luminaires for repair, service, maintenance, and energy-efficiency lighting retrofit upgrades.

The key phrase is existing nonresidential luminaires. The certificate is not a general commercial wiring credential and it is not a new-lighting installation certificate.

What Work Is Included in 07A?

Washington specifically includes several common lighting-maintenance and retrofit tasks within the specialty.

• Repair of existing nonresidential luminaires
• Service and maintenance of existing nonresidential luminaires
• Replacement of ballasts
• Replacement of sockets
• Installation of listed lighting retrofit reflectors
• Installation of listed lighting retrofit kits
• Approved energy-efficiency lighting retrofit upgrades
• Replacement or retrofit of remote-located ballasts with approved products

The work should remain tied to the existing luminaire and approved retrofit components. If the job starts looking like new branch-circuit construction, the specialty line has probably been crossed.

Most Work Must Stay Inside the Existing Luminaire Housing

Washington says 07A work is limited to the luminaire body, except for remote-located ballasts that may be replaced or retrofitted with approved products.

This is one of the simplest ways to understand the specialty. Picture the existing luminaire as the work zone. Components inside that housing can be maintained, repaired, or retrofitted when the task fits 07A. Once the project leaves that work zone and starts altering the building's branch-circuit system, the job changes.

Knowing that boundary is useful on the exam, but it is even more useful when a customer says, "While you're already up there, can you just move that fixture six feet?"

Ballast Replacement Is Inside 07A

Ballasts are one of the clearest examples of 07A work. Washington expressly includes ballast replacement within the specialty.

Candidates should understand basic ballast function, line and load connections, equipment labeling, proper replacement, grounding and bonding, and safe servicing practices.

A ballast problem may look routine, but the electrician still needs to identify the correct replacement, follow listing and installation instructions, and keep the work inside the existing luminaire or approved remote-ballast arrangement.

Socket Replacement Is Also Inside 07A

Washington also expressly includes replacement of luminaire sockets. That can involve removing a failed socket, installing the proper replacement, reconnecting conductors inside the luminaire, and confirming that the finished repair complies with the equipment and code requirements.

Study socket ratings, conductor condition, temperature considerations, grounding and bonding, and listed-equipment requirements. A tiny component can still create a very large headache if the wrong part is installed.

Listed Lighting Retrofit Reflectors and Kits Are Included

Energy-efficiency upgrades are a core reason the 07A specialty exists. Washington allows installation of listed lighting retrofit reflectors and kits inside existing luminaires.

The word listed matters. Retrofit components need to be appropriate for the existing luminaire and installed in accordance with their listing, labeling, instructions, and applicable NEC requirements.

A retrofit is not an excuse to improvise a new fixture out of random parts. The goal is to upgrade the existing luminaire using products intended and approved for that purpose.

Remote Ballasts Are the Main Exception to the Luminaire-Body Boundary

Most 07A work stays inside the luminaire body. Washington makes an exception for remote-located ballasts, which may be replaced or retrofitted using approved products.

That exception is specific. It does not create a general right to alter remote branch circuits, install new lighting circuits, or move the luminaires served by those ballasts.

Treat the remote-ballast allowance as a narrow maintenance exception, not a secret door into a broader electrical license.

What 07A Does Not Allow

Washington is very clear about the limits of the 07A specialty.

• Installing new luminaires
• Installing new branch circuits
• Moving or relocating existing luminaires
• Altering existing branch circuits
• Using lighting retrofit work as a reason to redesign the building's lighting distribution system
• Plumbing work regulated under Washington plumbing law

If a project needs new fixture locations, new supply points, additional branch-circuit wiring, or other premises-wiring changes, 07A is no longer enough by itself.

07A Is for Nonresidential Lighting

The specialty applies to nonresidential luminaires. That includes commercial, institutional, industrial, and other qualifying nonresidential environments where existing luminaires need maintenance or approved retrofit work.

Residential maintenance is a different Washington specialty identified as 07B. The two certificates may both involve luminaires, but the occupancy and scope rules are not interchangeable.

Exam questions may test whether the work itself fits 07A and whether the location is the kind of nonresidential environment contemplated by the specialty.

07A Requires 720 Hours Before Exam Eligibility

Washington classifies 07A as a 2,000-hour specialty. The current experience table allows a trainee to become exam-eligible after 720 qualifying supervised hours.

Until the examination is successfully completed, the trainee must work under 100 percent supervision by an appropriately certified electrician.

What Happens After You Pass at 720 Hours?

After passing the 07A examination, Washington can issue a nonrenewable zero-percent-supervision modified training certificate.

That modified certificate allows the trainee to work without supervision in 07A while completing the remaining experience required for the full 2,000-hour specialty certificate.

Washington allows only one zero-percent-supervision certificate in the specialty, and it is valid for no more than two years. If the trainee has not finished the required experience when it expires, the applicable 75-percent-supervision modified training certificate is required while the remaining hours are completed.

Keep Accurate Experience Records

Labor & Industries reviews work-experience records and affidavits to determine whether a trainee qualifies for the 07A exam and, later, for full specialty certification.

Keep records showing employer, dates, hours, supervising electrician, specialty classification, and the type of lighting-maintenance or retrofit work performed.

The initial 720 supervised hours required for examination eligibility cannot simply be replaced by classroom training. Washington also limits how training-school credit can be applied toward the 2,000-hour certification requirement.

The Current 07A Electrician Exam at a Glance

Current 07A Electrician Exam Blueprint

Electrical Equipment is the largest technical category at about six questions. Grounding & Bonding and General Trade Knowledge & Theory contribute about three each, while Overcurrent Protection contributes about two.

Electrical Equipment Is the Biggest Technical Category

NEC 400-427 and 455-480 contribute about six questions, making Electrical Equipment the largest part of the 07A technical section.

Review topics such as:

• Flexible cords and cables where applicable
• Luminaires and associated equipment
• Equipment ratings and markings
• Ballasts and drivers
• Sockets and lampholders
• Listed retrofit components
• Equipment connections
• Maintenance of existing lighting equipment

The specialty is narrow, so equipment knowledge carries a lot of weight. If there is one section where fast code navigation matters, this is it.

Grounding and Bonding Are About Three Questions

NEC 250 contributes about three questions. Existing luminaires and retrofit work can involve metal housings, grounding connections, bonding paths, replacement components, and fault-current safety.

Review equipment-grounding conductors, bonding of metal enclosures, continuity, fault-current paths, and proper reconnection after maintenance.

A lighting retrofit should improve efficiency, not create a surprise metal box with a bad fault path.

General Trade Knowledge and Theory Are About Three Questions

The current outline assigns about three questions to General Trade Knowledge & Theory. Even a lighting-focused specialty needs basic electrical theory.

• Voltage
• Current
• Resistance
• Power
• Ohm's law
• Basic AC theory
• Series and parallel concepts
• Lighting power and equipment ratings
• Basic troubleshooting
• Electrical measurements

Theory questions are good places to save time. If you can answer them from knowledge, you can spend more of the hour on code lookups.

Overcurrent Protection Is About Two Questions

NEC 240 contributes about two questions. Review conductor protection, equipment protection, overcurrent-device ratings, and the relationship between existing lighting equipment and the branch circuit that supplies it.

Remember the licensing boundary. The exam may expect you to understand the branch-circuit protection even though 07A does not authorize alteration of the existing branch circuit.

Hazardous Locations Add About One Question

The current 07A technical blueprint assigns about one question to NEC 500-516 Hazardous Locations.

Review enough classified-location material to recognize special luminaire requirements, equipment suitability, listing considerations, and installation restrictions that can affect existing lighting equipment.

This category does not expand the 07A license beyond luminaire maintenance and retrofit work. It simply means specialty candidates need enough code knowledge to handle the conditions in the exam outline.

The Washington Codes Section Is Half the Published Exam

The Washington Codes section contains 17 questions, the same number as the entire NEC & Theory section. It deserves equal preparation time.

Study:

• Chapter 19.28 RCW
• Chapter 296-46B WAC
• WAC 296-46B-920 specialty scope
• WAC 296-46B-945 experience and exam eligibility
• Trainee supervision
• Modified training certificates
• Permits and inspections
• Electrician certification
• Electrical contractor requirements
• Renewal and continuing education

A candidate who studies only luminaires has prepared for roughly half the published questions. Washington law is not the side dish here.

The Current Exam Is Open Book

Washington's current exam rules identify electrical examinations as open book. The current PSI bulletin is based on the 2020 National Electrical Code, current Chapter 19.28 RCW, and current Chapter 296-46B WAC.

Original copyrighted references may be highlighted, underlined, and permanently tabbed. Printed copies of RCW 19.28 and WAC 296-46B may be used when prepared according to the testing-center rules.

Personal handwritten notes, removable tabs, sticky notes, and writing in the references during testing are prohibited. A silent nonprinting nonprogrammable calculator is allowed.

Current Exam NEC vs. Current Field NEC

Washington currently uses the 2023 NEC for field installations and inspections. The current licensing-exam bulletin still uses the 2020 NEC.

Washington has adopted the 2026 NEC with a delayed effective date of December 31, 2026, when it will replace the current 2023 field edition.

• For the exam: follow the current PSI and L&I testing-reference instructions.
• For field work: follow the NEC edition and Washington amendments currently in force.

The Three Core Exam References

A practical 07A study set begins with:

• 2020 National Electrical Code for the current exam
• RCW Chapter 19.28
• WAC Chapter 296-46B

The Washington General Electrician Book Package contains these same three core Washington electrical exam references. The package is broader than 07A, so use the current 07A blueprint and specialty scope to focus your study.

Open-Book Strategy for a Fast Two-Hour Exam

The current 07A exam gives one hour for 17 NEC/Theory questions and one hour for 17 Washington Codes questions. That is a manageable pace if you know the books before test day.

1. Memorize the scope. Existing nonresidential luminaire, luminaire body, remote-ballast exception, no new fixtures, no moving fixtures, no branch-circuit alteration.
2. Tab the NEC lighting and electrical-equipment sections you use most.
3. Practice grounding and bonding lookups.
4. Review overcurrent protection without confusing knowledge with 07A authority.
5. Practice basic theory until routine questions are fast.
6. Learn WAC 296-46B-920 and 296-46B-945.
7. Practice a 17-question technical section in one hour.
8. Practice a 17-question Washington Codes section in one hour.

Apply Through Labor & Industries Before PSI

07A electrician candidates follow Washington's 2,000-hour specialty pathway through Labor & Industries. L&I reviews the required experience and training before approving the candidate to sit for the exam.

Once approved, the candidate receives the information needed to schedule with PSI. The current PSI bulletin gives electrician candidates one year from the L&I approval date to pass all required sections.

Current Retest Rules

The current PSI bulletin requires a 14-day wait after a failed examination attempt before retesting.

After a third failed attempt, future attempts require a three-month wait from the most recent failure.

A short exam can feel friendly right up until the same weak topic appears three times. Use the score report to fix the problem before the next appointment.

Current PSI Exam Fee

The 07A Electrician exam totals two testing hours. PSI's current time-based fee schedule lists $55 for a two-hour examination.

Confirm the live amount at scheduling because testing fees can change.

Current Washington Application and Certificate Fees

Washington's current fee schedule lists $102.20 for the zero-percent-supervision modified training certificate pathway.

The current journey-level, specialty, or reciprocal electrician application, including the original certificate and processing fee, is $114.60.

Use the current WAC 296-46B-909 fee schedule when you are ready to pay. Older forms and older blog posts can carry yesterday's price tag.

Renewal Is Every Three Years

Washington specialty electrician certificates renew every three years and expire on the holder's birthdate.

Current specialty electrician renewal is $92.60 online or $106.40 by mail, fax, or in person.

If a certificate has been expired for more than 90 days, Washington requires retesting before recertification.

Continuing Education Requires 24 Hours

For a normal three-year certificate period, Washington electricians currently need 24 hours of approved continuing education.

• At least 8 hours of code update
• At least 4 hours of RCW/WAC education
• 12 additional hours of approved continuing education

Keep renewal education separate from the initial 24 hours of basic trainee classroom instruction required for a 2,000-hour specialty certificate. The numbers match, but the purpose is different.

A Practical 07A Study Plan

1. Start with WAC 296-46B-920. Memorize exactly what 07A includes and excludes.
2. Learn the luminaire-body boundary. Know the remote-ballast exception.
3. Study listed retrofit kits and reflectors.
4. Review ballast and socket replacement concepts.
5. Study NEC Electrical Equipment topics. They make up the largest technical category.
6. Review NEC 250 Grounding & Bonding.
7. Review NEC 240 Overcurrent Protection.
8. Practice basic electrical theory.
9. Study Washington laws and rules as a full half of the published exam.
10. Take timed 17-question technical and 17-question Washington Codes practice sections.

Study Like a Lighting Maintenance Electrician

A useful study method is to picture a real service call in an office, warehouse, school, store, hospital, parking structure, or other nonresidential building.

Start with the existing luminaire. Is the problem a ballast, socket, connection, listed retrofit component, grounding issue, equipment defect, or approved remote ballast? Can the repair stay inside the luminaire body?

Then check the licensing boundary. Is someone asking for a new luminaire? A new branch circuit? A relocated fixture? A changed branch circuit? If yes, the work has stepped outside 07A.

Frequently Asked Questions

Conclusion

Washington's 07A Nonresidential Lighting Maintenance & Lighting Retrofit Electrician certificate is a narrow specialty built around existing nonresidential luminaires. It is designed for technicians who repair, service, maintain, and perform approved energy-efficiency retrofit work without turning those projects into broader electrical construction.

The core scope rule is straightforward. Most work must stay inside the housing of the existing nonresidential luminaire. Washington specifically includes replacement of ballasts and sockets and installation of listed lighting retrofit reflectors and kits.

Remote-located ballasts are the main exception to the luminaire-body boundary. They may be replaced or retrofitted with approved products. That exception remains narrow and does not authorize branch-circuit alterations or new lighting distribution work.

The exclusions are just as important as the included work. 07A does not allow installation of new luminaires, installation of new branch circuits, movement or relocation of existing luminaires, or alteration of existing branch circuits. Washington specialty rules also do not give 07A authority to perform regulated plumbing work.

These limits matter because lighting retrofit projects can grow quickly. A customer may start by asking for a ballast replacement and finish by asking for three new fixture locations. The first task can fit 07A. The second request can move the project outside the specialty.

The experience pathway is designed for a 2,000-hour specialty. Washington currently requires 720 qualifying supervised hours before a trainee becomes eligible for the 07A examination. Until the exam is passed, the trainee works under 100 percent supervision.

After passing, Washington can issue a nonrenewable zero-percent-supervision modified training certificate. This lets the trainee work unsupervised in 07A while completing the remaining experience required for full certification.

Full 07A certification requires 2,000 qualifying work hours. The 2,000-hour pathway also requires 24 hours of approved basic trainee classroom instruction. The trainee may have only one zero-percent-supervision certificate in the specialty, and it is valid for no more than two years.

The current 07A Electrician exam is one of the smaller Washington electrical specialty exams. NEC and Theory contains about 17 scored questions and allows one hour. Washington Codes also contains 17 questions and allows one hour. The published total is 34 scored questions over two section-hours.

Electrical Equipment is the largest technical category at about six questions. That makes sense for a certificate focused almost entirely on existing luminaires, internal components, and approved retrofit products.

Grounding & Bonding contributes about three questions, as does General Trade Knowledge & Theory. Overcurrent Protection contributes about two. Introduction, General Requirements, and Hazardous Locations contribute about one each.

The Washington Codes section is half the published exam, so it deserves equal study time. Candidates should understand 07A scope, experience requirements, trainee supervision, modified training certificates, electrician certification, contractor rules, permits, inspections, renewal, and continuing education.

The current exam is open book. PSI currently bases Washington electrical exam questions on the 2020 National Electrical Code, current RCW 19.28, and current WAC 296-46B. Permanent index tabs, highlighting, and underlining are allowed under the current test rules, while removable tabs, sticky notes, and personal handwritten notes are prohibited.

Washington field work currently uses a different NEC edition. The 2023 NEC is currently adopted for installations and inspections. Washington has adopted the 2026 NEC with a delayed effective date of December 31, 2026, when it will replace the current 2023 field edition.

That means candidates should keep exam preparation and field compliance separate. Use the current testing reference for the licensing exam and the currently adopted field code for actual work. Check the PSI and L&I instructions again close to test day because those dates do not always move together.

Electrician candidates must first qualify through Labor & Industries before scheduling with PSI. Approved candidates currently have one year from the approval date to pass all required sections. A failed attempt requires a 14-day wait, and after a third failure the waiting period increases to three months.

PSI currently lists $55 for a two-hour examination. Washington's current fee schedule lists $102.20 for the zero-percent-supervision modified training certificate pathway and $114.60 for the specialty electrician application including the original certificate and processing fee.

Once fully certified, a 07A electrician renews every three years on the certificate holder's birthdate. Current renewal is $92.60 online or $106.40 by mail, fax, or in person. If the certificate is more than 90 days expired, retesting is required before recertification.

A normal three-year renewal period requires 24 hours of approved continuing education, including at least eight hours of code update and four hours of RCW/WAC education. Keep those renewal hours separate from the 24 hours of basic trainee classroom instruction used for initial 2,000-hour certification.

Strong 07A preparation combines lighting knowledge with scope discipline. Learn ballasts, sockets, listed retrofit kits, grounding, bonding, basic theory, and electrical-equipment rules. Then learn exactly where the luminaire ends and the building wiring begins. In this specialty, that boundary is almost the whole story.

Key Takeaways

• Washington 07A is a 2,000-hour specialty, with examination eligibility after 720 qualifying supervised hours.
• The specialty is limited to repair, service, maintenance, and approved retrofit work inside existing nonresidential luminaires, with a narrow exception for approved remote-ballast replacement or retrofit.
• 07A does not authorize new luminaires, new branch circuits, relocation of existing luminaires, or alteration of existing branch circuits.
• The current exam has about 17 NEC/Theory questions in 1 hour plus 17 Washington Codes questions in 1 hour, for 34 published scored questions.
• The current exam is open book and uses the 2020 NEC plus current RCW 19.28 and WAC 296-46B, while Washington field work currently uses the 2023 NEC.

Plain-Language Summary

Washington's 07A Nonresidential Lighting Maintenance & Lighting Retrofit Electrician certificate is for people who repair, maintain, service, and retrofit existing nonresidential luminaires.

The specialty is narrow on purpose. Most work has to stay inside the housing of the existing luminaire.

Washington specifically allows replacement of ballasts and sockets. It also allows installation of listed lighting retrofit reflectors and listed retrofit kits.

Remote-located ballasts are a special exception. They can be replaced or retrofitted with approved products even though they are not inside the luminaire body.

The specialty does not allow installation of new luminaires. It also does not allow new branch circuits, moving or relocating existing luminaires, or altering existing branch circuits.

That means 07A is a lighting-maintenance certificate, not a general commercial electrical license.

The current training path requires 720 qualifying supervised work hours before the trainee can take the 07A exam. Full certification requires 2,000 hours.

Until the exam is passed, the trainee works under 100 percent supervision. After passing, Washington can issue a nonrenewable zero-percent-supervision modified training certificate that allows unsupervised 07A work while the remaining hours are completed.

Because 07A is a 2,000-hour specialty, the certification pathway also requires 24 hours of approved basic trainee classroom instruction.

The current 07A Electrician exam has 17 NEC and Theory questions and gives you one hour. The Washington Codes section also has 17 questions and gives you one hour. That is 34 published scored questions across two hours.

Electrical Equipment is the largest technical category at about six questions. Grounding & Bonding and General Trade Knowledge & Theory are about three questions each. Overcurrent Protection is about two. Introduction, General Requirements, and Hazardous Locations are about one each.

The Washington Codes section is just as large as the technical section. Study WAC 296-46B-920 for specialty scope and WAC 296-46B-945 for the experience pathway. Also study permits, inspections, certification, trainee supervision, contractor requirements, renewal, and continuing education.

The exam is open book and currently uses the 2020 National Electrical Code, current RCW 19.28, and current WAC 296-46B.

Washington field installations currently use the 2023 NEC. The 2026 NEC is scheduled to replace the 2023 field edition on December 31, 2026. Always check the current exam bulletin before test day because the testing-reference edition may change on a different schedule.

PSI currently lists $55 for a two-hour exam. Washington currently lists $102.20 for the zero-percent-supervision modified training certificate and $114.60 for the specialty electrician application including the original certificate and processing fee.

The full certificate renews every three years on your birthdate. Current renewal is $92.60 online or $106.40 by mail, fax, or in person. A normal three-year renewal period requires 24 hours of approved continuing education, including eight hours of code update and four hours of RCW/WAC education.
