To do low voltage work in Minnesota, you need a Power Limited Technician license from the Department of Labor and Industry. If your company plans to offer that work to the public, the business also needs a Technology Systems Contractor license. The individual license requires 36 months of documented field experience and a passing score on an 80-question state exam. The contractor license adds a $25,000 surety bond, proof of insurance, and a designated responsible technician.
What Counts as Low Voltage Work
Minnesota’s statutes call it “technology circuits or systems” rather than low voltage. The term covers class 2, class 3, and class 4 circuits used for remote control, signaling, alarm, audio, communication, and antenna systems, along with low-voltage lighting powered by a class 2 or class 3 supply as defined by the National Electrical Code.1Minnesota Office of the Revisor of Statutes. Minnesota Statutes 326B.31 In the field, that means fire alarm panels, security and access control, structured data and telecom cabling, intercom and audio distribution, and similar installs isolated from higher-voltage systems.
All of this work must be done by W-2 employees of a licensed technology systems contractor or electrical contractor. The one exception is work performed only on an employer’s own premises by that employer’s own employees, provided the employer has registered a responsible licensed individual with the Department.2Minnesota Department of Labor and Industry.

Which License Do You Need
Minnesota splits the credential in two. The Power Limited Technician (PLT) license is the personal credential that authorizes you to install, alter, repair, plan, lay out, and supervise technology circuit and system work.3Minnesota Department of Labor and Industry. Important Information for Power Limited Technicians Without one, you cannot touch low voltage wiring on a job unless you are working under the direct supervision of someone who holds it.
The Technology Systems Contractor license is the business credential. Any company offering technology systems installation to the public has to hold one, and every contractor must designate a responsible Power Limited Technician who is personally accountable for the company’s work.4Minnesota Office of the Revisor of Statutes. Minnesota Statutes 326B.33 – Licenses For a sole proprietorship, that responsible individual must be the owner or a managing employee. For a partnership, a general partner or managing employee. For a corporation, an officer or managing employee. A managing employee serving in that role must actively perform electrical work for the contractor and cannot work as a technician for any other contractor.
If you are a one-person shop installing low voltage systems for customers, you need both.
Qualifying for the Power Limited Technician License
Minnesota requires at least 36 months of qualifying experience before you can sit for the PLT exam. The Department caps credit at 2,000 hours per year, so plan on documenting at least 6,000 total hours.5Minnesota Department of Labor and Industry. Power Limited Technician Work Experience Verification Form At least 12 of those 36 months must come from hands-on wiring and installation of technology circuits or systems. The rest can come from planning, layout, supervision, and maintenance.6Minnesota Office of the Revisor of Statutes. Minnesota Rules 3800.3520
If you finished an approved two-year post-high school electrical or technical program, you can receive up to 12 months (or 2,000 hours) of credit toward the requirement, cutting your field time by a third.7mn.gov. Power Limited Technician The program must be approved by the Department of Labor and Industry for the credit to count.
You document hours on the Department’s Power Limited Technician Work Experience Verification form. Every employer you worked under must sign off on the hours claimed. Military experience can also count when verified through the Department’s forms. Incomplete or inconsistent documentation is one of the most common reasons applications stall, so get it right the first time.
The PLT Exam
Once the Department approves your application, you receive an exam eligibility notice authorizing you to schedule the test. The PLT exam has 80 questions, a passing score of 70%, and a time limit of 5½ hours.8Minnesota Department of Labor and Industry. Electrical License Examination Guide
Content draws from the National Electrical Code as it applies to technology systems:
- General code knowledge, including mandatory versus permissive rules, the scope and purpose of the NEC, and the authority of the inspector
- Wiring and protection topics such as grounding, bonding, overcurrent protection, and GFCI requirements
- Wiring methods and materials, including conductor protection, raceway requirements, and cable installation standards
- Equipment and systems: technology circuit classifications, fire alarm and signaling systems, communication circuits, and low-voltage lighting
The test leans on NEC code references, so most people who pass study with the current NEC codebook and practice applying it to technology system scenarios rather than memorizing rules in isolation.
What a Business Needs for the Contractor License
Before you can apply, the business has to be registered with the Minnesota Secretary of State. On the application, you list the company’s legal name, tax identification number, and contact information, and you name your responsible Power Limited Technician by license number.9mn.gov. Technology Systems Contractor
Every technology systems contractor must post a $25,000 surety bond on the Department’s required form. The bond protects the state and anyone who suffers financial loss because the contractor failed to comply with the Electrical Act, related rules, or contract obligations, and it must stay active for the entire term of licensure.10Minnesota Department of Labor and Industry. Technology System Contractor Surety Bond
You also have to file a certificate of insurance showing commercial general liability coverage of at least $100,000 per occurrence and $300,000 aggregate for bodily injury, plus $50,000 for property damage. A single combined limit of $300,000 per occurrence and $300,000 aggregate also satisfies the requirement.11Minnesota Department of Labor and Industry. Certificate of Insurance Covering General Liability and Property Damage Workers’ compensation coverage is required unless the business qualifies for a statutory exemption.12Minnesota Department of Labor and Industry.

Fees and How to Apply
Applications and renewals run through the Department’s iMS online portal, which also handles exam scheduling. Paper applications by mail are accepted.13Minnesota Department of Labor and Industry. Access iMS License Management System
The Technology Systems Contractor application fee is $188, and renewal is the same $188. Letting the contractor license expire before renewing pushes the fee to $278.9mn.gov. Technology Systems Contractor The individual PLT renewal is $53, with a late renewal fee of $73.14Minnesota Department of Labor and Industry. CCLD Licensing Fee Schedule
Once the Department reviews and approves your materials, it issues the exam eligibility notice. After the testing center reports a passing score, the Department issues the license and mails a physical card. Keep it available for inspection whenever you are performing work on site.
Keeping Your License Active
The PLT license lasts two years and expires on the anniversary of your issue date.7mn.gov. Power Limited Technician Before you renew, you have to complete 16 continuing education credits: 4 in code-related coursework and 12 in non-code subjects.15Minnesota Department of Labor and Industry. Continuing Education for Licensees The Department publishes a searchable list of approved courses, which run from 1 to 16 credits apiece.
Don’t let it lapse. A $20 late fee is the small problem. The bigger problem: a license that has been expired for more than two years cannot be reinstated through the normal renewal process. You have to retake and pass the exam to get licensed again.16Minnesota Department of Labor and Industry. Electrical License Reciprocity
Penalties for Working Without a License
Minnesota treats unlicensed electrical work as a misdemeanor. The commissioner can issue administrative orders requiring violators to correct the problem, cease and desist, and pay monetary penalties up to $10,000 per violation.17Minnesota Office of the Revisor of Statutes. Minnesota Statutes 326B.082 If a stop work order is issued and ignored, that climbs to $5,000 for each day the work continues. The commissioner can also seek injunctive relief in district court without proving irreparable harm. These penalties move faster than most people expect, and the Department does not need a court order to impose them.
Out-of-State Applicants
Minnesota has reciprocity agreements with several states, including Iowa, North Dakota, South Dakota, and Nebraska, that allow certain electricians to get a Minnesota license without retaking the exam. Those agreements currently cover the Class A journeyworker and master electrician licenses.16Minnesota Department of Labor and Industry. Electrical License Reciprocity The Department’s published reciprocity list does not specifically mention the Power Limited Technician license, so if you hold an out-of-state low voltage credential, contact the Department directly to confirm whether reciprocity applies before relying on it.
For any reciprocal application, the general requirements are the same: current license in good standing in the originating state, obtained through a state-level exam (not a city or local test), held for at least one year, with no prior failure of the equivalent Minnesota exam. The reciprocal application and exam fee is $50.
