Maine Master Electrician License: Requirements and How to Apply
Maine's Electricians' Examining Board issues the master electrician license, and Prov gives the exam. Everything below comes from 32 M.R.S. chapter 17, the Board's own pages and Prov's Maine bulletin (effective October 31, 2026).
What a master may do
A master electrician may make electrical installations without limitation and is responsible for the work of everyone they supervise. A master may supervise any number of licensed journeymen, journeymen-in-training and limited electricians, plus two apprentices, two helpers who are enrolled in or have finished the 576-hour course, or one other helper (32 M.R.S. §1202-B). Electrical permits from the Board are applied for by a master or limited electrician (32 M.R.S. §1102-C).
Experience and training
To sit the exam you need Board approval and one of these, each with the Board's 576-hour course of study (32 M.R.S. §1202-B):
| Route | Hours |
|---|---|
| Journeyman | 4,000 hours as a licensed journeyman |
| Journeyman-in-training | 6,000 hours as a journeyman-in-training |
| Helper or apprentice | 12,000 hours as a licensed helper or apprentice |
| Comparable | Experience, education or training the Board accepts |
The Board decides case by case whether a limited electrician has broad enough experience to take the master exam.
How to apply
- Apply to the Board for the exam with your documentation.
- Wait for approval. The Board emails an approval notice; a score earned before approval is void.
- Schedule with Prov at a test center in Auburn, Bangor or Presque Isle, any Prov center in the U.S., or remotely through Examroom.ai. The exam fee is $90.
- Apply for the license after you pass, with a 45-hour National Electrical Code course completed within the two years before you apply.

Licensed in another state?
The Board lists master reciprocity agreements with New Hampshire, Massachusetts, Rhode Island and Vermont. State law requires at least 8,000 hours licensed and working in a state with equivalent standards that gives Maine licensees the same privilege, and the Board may waive the 576-hour course (32 M.R.S. §1206).
Renewal and continuing education
Before each renewal you complete 15 hours of a Board-approved course on the current National Electrical Code. A license can be renewed up to 90 days after it expires with a late fee (32 M.R.S. §1204).
