Low-voltage licensing
Maine
Maine requires Electrician licensing through the State Electricians' Examining Board under the Department of Professional and Financial Regulation. The Limited Electricians' license covers specific low-voltage scopes (signaling, communications, fire alarm, security). Master and journeyman electrician tiers exist for full electrical scope.

Common pitfalls
Mistakes we see installers make when navigating Maine licensing.
- Maine's Limited license is scope-restricted; using it for work outside the limited categories (e.g., a 277V circuit) invalidates the license for that job.
- Biennial renewal with continuing education required. CE hours scale by license tier.
- Portland and Bangor have local permit and inspection layers on top of state licensing.
