Minnesota Low Voltage License Requirements (2026)

Minnesota regulates technology circuits and systems through the DLI Board of Electricity. A Power Limited Technician (PLT) is the individual license for planning, laying out, installing, altering, repairing, and supervising technology circuits and systems. A Technology Systems Contractor (TSC) is the licensed business and must designate a responsible PLT or master electrician. The statutory technology-system definition includes class 2, class 3, class 4, antenna and communication circuits, and qualifying low-voltage lighting; local permits and inspections still apply.

Regulatory Body

Minnesota Department of Labor and Industry — Board of Electricity / local authority having jurisdiction (DLI / AHJ) is the statutory authority responsible for issuing and enforcing this license under Minn. Stat. §§ 326B.31-.399; Minn. Rules chapter 3800; local ordinances. DLI licenses PLTs and Technology Systems Contractors; local authorities issue permits and administer inspections.

Eligibility Requirements

Applicants must be at least 18 years old. Applicants must provide a Social Security Number. Minnesota does not publish a general PLT residency rule. A nonresident TSC applicant must meet the current application’s registered-agent requirements where applicable.

Good moral character

Complete current DLI disclosures accurately.

Background investigation

Follow the current DLI application; do not assume a universal fingerprint requirement.

Experience and Education

The experience bar is 3 years of PLT applicants need 36 months of acceptable experience. The DLI experience rule requires at least 12 months installing technology circuits or systems and limits the credit allowed for each type of work., and it must be backed by verifiable records — typically payroll, tax, project, or supervisor documentation covering the claimed period.

Accepted proof of experience or eligibility

• DLI experience documentation requested for examination approval
• Employer and supervision records
• Training records where credit is claimed

Education substitution

Use DLI’s current experience rule for allowable education or program credit; do not assume a blanket two-year-degree substitution.

Exam Requirements

Testing provider or authority: DLI-approved testing provider; confirm the current provider and candidate bulletin before scheduling.. The following examination requirements cover the pathways described in this guide; follow each part's classification, waiver, and local-scope conditions. Unpublished format details do not remove an examination requirement:

• Minnesota Power Limited Technician examination — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin

Examination fee: Confirm current examination and license fees with DLI.

Retake policy: Follow the current DLI testing instructions.

Insurance and Bonds

No license surety bond is mandated statewide here under the cited sources, though project-specific or public-works bonding obligations can still attach to a given job.

General liability

Confirm current TSC bond and insurance documentation requirements with DLI before applying.

Workers' compensation

Employers must meet applicable Minnesota workers’ compensation requirements.

Additional financial requirements

Confirm current business-application requirements with DLI.

Fee Schedule

Renewal and Continuing Education

The Minnesota Power Limited Technician and Technology Systems Contractor License runs on a 2 years renewal cycle. No separate statewide renewal fee is listed in the cited sources. Renew the individual and business credentials under their current DLI schedules.

Continuing education: DLI’s current PLT table lists four code hours and 12 other hours; confirm the current cycle and course rules.

Reciprocity

For this classification, Minnesota does not recognize the NASCLA Accredited Examination.

DLI recognizes certain reciprocal electrical licenses; verify whether a current agreement covers the exact PLT credential before applying.
