Oregon Low Voltage License Requirements: Class A and B Explained

Oregon low voltage license requirements run through the Building Codes Division, which issues two limited energy technician licenses: Class A (LEA) and Class B (LEB). Which one you need depends on whether you want to work on protective signaling systems — fire alarms, burglar alarms, and nurse call — or stick to data, communications, HVAC controls, and other non-life-safety low-voltage work. Both licenses require documented training and experience, a passing score on Oregon’s exam, and employment under a licensed contractor before you can take jobs.

Class A and Class B: What Each One Covers

The Limited Energy Technician Class A license authorizes installation, alteration, and repair of all limited energy systems, including protective signaling.¹ Fire alarm panels, burglar alarms, nurse call, data cabling, sound systems, HVAC controls — all of it falls inside an LEA’s scope.

The Class B license covers the same kinds of low-voltage work but excludes protective signaling.² An LEB holder can wire data networks, run communication cables, install HVAC control circuits, and handle similar systems, but cannot work on fire alarm, burglar alarm, or nurse call installations. The LEB has lower hour thresholds, so if your work is centered on building automation or telecom, it gets you licensed faster.

Training and Experience You’ll Need

Oregon offers three qualifying paths for each license. You pick one; the state does not let you mix and match.

Class A (LEA)

Complete a state-approved Oregon apprenticeship in limited energy work, or
Provide official transcripts for 432 hours of required classroom training plus verification of 6,000 hours of on-the-job experience broken down into specific work categories (the 300 percent rule applies), or
Provide verification of 12,000 hours of out-of-state work experience broken into specific categories, including trade-specific installation experience in protective signaling such as fire alarm, nurse call, and burglar alarm.¹

Class B (LEB)

Complete a state-approved Oregon apprenticeship, or
Provide transcripts for 288 hours of classroom training, verification of 4,000 hours of on-the-job experience (300 percent rule applies), and completion of a board-approved 32-hour training program, or
Provide verification of 8,000 hours of out-of-state experience (300 percent rule applies) plus the 32-hour board-approved program.³

The 32-hour program can be taken after your application is approved, but it must be done before you’re licensed.

The 300 Percent Rule

Your experience hours must be spread across specific work categories: residential, commercial, industrial, and others. The state will credit no more than three times the minimum for any single category.⁴ If a category’s minimum is 1,000 hours and you logged 5,000 in it, Oregon will count only 3,000. Applicants whose careers have been narrow often find they need more hours in a category they’ve barely touched, even when their raw total blows past the overall minimum. Check your category distribution before you file.

Military and Out-of-State Experience

Military electrical experience is evaluated case by case. Veterans should gather their DD-214, Verification of Military Experience and Training (VMET) documents, and any training certificates before contacting BCD. There’s no fixed conversion formula, so credit depends on what you can document and the work you actually performed.

Experience earned in another state uses the out-of-state pathway above. Oregon does not currently list any reciprocity agreements for limited energy technician licenses, even though it has reciprocity for general journeyman and supervising electrician licenses with Idaho, Montana, Washington, and several other states.⁵ If you hold an LEA or LEB equivalent from another state, plan on applying through the out-of-state hours route and sitting for Oregon’s exam.

How to Apply

The application is Form 440-2570, available from the BCD website.⁶ Submit the completed form, supporting documentation, and fees to the Department of Consumer and Business Services.⁷

The experience verification is the piece that most often slows applications down. Former employers or supervisors have to sign off on the specific number of hours you worked in each electrical category, broken out to match the Electrical Experience Verification form (Form 440-2570A).⁴ A lump total won’t do. If you qualified through classroom training, include official transcripts or certificates. Vague verification letters are where packages stall, so push your past supervisors to be specific.

The Exam

Once BCD approves your application, you’ll get notification of eligibility to schedule the exam. It covers the National Electrical Code and Oregon-specific amendments, and you have to pass to get your license. There’s no alternative route around it for Oregon applicants.

The questions test working knowledge of the code, not raw memorization. If you came in through a structured apprenticeship, the content should feel familiar. If you qualified on experience alone, a code review course before your test date is worth the money.

Working for a Licensed Contractor

Holding the technician license doesn’t let you take jobs on your own. Both LEA and LEB holders must either hold an electrical contractor license themselves or work for a licensed electrical contractor, a licensed limited energy contractor, or a single employer in an industrial plant.³ The contractor license is a separate business-level license, and the company has to continuously employ at least one full-time limited energy technician or general journeyman as its signing supervising electrician.⁸

Your scope on any job cannot exceed what your signing supervisor is authorized to perform. If you hold an LEA but your company’s signing supervisor only holds an LEB, the company cannot take protective signaling work under that permit.² Your personal license sets your ceiling; your employer’s signing supervisor sets the project-level limit.

Penalties for Unlicensed Work

Oregon prohibits making electrical installations without an appropriate license and also prohibits property owners from knowingly letting unlicensed people do electrical work on their property.⁹ The Electrical and Elevator Board can impose civil penalties, and supervising electricians who allow unlicensed work face fines, license conditioning, suspension, or revocation.¹⁰

There’s a quieter consequence most people overlook. Oregon bars unlicensed persons from maintaining a lawsuit involving electrical work they performed without a license.⁹ If a client refuses to pay for work you did before your license cleared, the courts won’t hear your collection case.

Renewal and Continuing Education

Oregon electrical licenses renew on a three-year cycle with an October 1 deadline. Both LEA and LEB holders must complete 8 hours of continuing education before each renewal, typically covering updates to the National Electrical Code and Oregon-specific amendments. Letting a license lapse brings reinstatement requirements more involved than a late fee, so mark the renewal date well ahead.
