What's on the Maine Master Electrician Exam?
The Maine Master Electrician exam has 100 questions in 4 hours, open book, and you need 70%. Prov writes and gives it for the Electricians' Examining Board.
The content outline
Prov's bulletin (effective October 31, 2026) breaks the exam down like this:
| Content area | Questions |
|---|---|
| Wiring Methods and Materials | 24 |
| Wiring and Protection | 19 |
| General Electrical Knowledge | 15 |
| Equipment for General Use | 15 |
| Special Equipment | 7 |
| Special Occupancies | 6 |
| Services, Feeders and Branch Circuits | 4 |
| Motors and Controls | 4 |
| Special Conditions | 4 |
| Communication Systems | 2 |
| Total | 100 |
Compared with the journeyman exam, the master exam leans much harder on Chapter 3 wiring methods (24 questions, against 12) and has far fewer motor questions (4, against 11). In our practice exam, general electrical knowledge draws on the NEC's general requirements in Chapter 1 as well as theory and calculations.
What you may bring
Prov's bulletin permits four references in the room:
- NFPA 70, National Electrical Code, 2026
- American Electricians' Handbook, 17th edition
- Mike Holt's Understanding Electrical Theory for NEC Applications (2022)
- The Maine electrical laws and rules
Permanent tabs and highlighting done beforehand are fine. Handwritten notes, formulas, sticky notes and taped-in index sheets are not.
The edition: 2026, not 2023
The October 2026 bulletin lists the 2026 NEC, which Maine enforces on installations started on or after July 1, 2026; the April 2026 bulletin still named 2023. Study material written for 2023 numbers several rules differently: load calculations moved from Article 220 to Article 120, and the underground burial rules from 300.5 to 300.7, for example.
Where Maine changes the 2026 NEC
Board rule Chapter 120 adopts the 2026 NEC with amendments. Several sit right in the master exam's biggest areas:
- NM cable (334.12(2)): Maine does not adopt the ban on NM cable exposed in dropped or suspended ceilings.
- Flexible cords (400.12(4)): Maine allows cords attached to building surfaces under 368.56(B) and 590.4, and one connection to a tension take-up device with no more than 6 feet of cord.
- Arc-flash marking (110.16): Maine keeps the 2023 rule; the dated label is required only on service and feeder equipment rated 1,000 amperes or more.
- GFCI (210.8): kitchen appliances listed in 210.8(D)(8), (9) and (10) are exempt, and dwelling outdoor outlets for water and sewer pumps need no GFCI.
- Receptacles at tubs and showers (406.9(C)(1)): only not within or directly over the tub or shower stall.
- EV charger emergency disconnect (625.43(D)(1)): not adopted.
How to study
- Own Chapter 3. Wiring methods and materials is a quarter of the exam: raceway fill, cable uses permitted and not permitted, boxes and supports.
- Practice look-up speed. Four hours for 100 questions is about 2½ minutes each.
- Tab Chapter 120. The Maine laws and rules are a permitted reference, so tab each amendment next to the NEC section it changes.
Practice for the exam
Our Maine Master practice test is weighted like Prov's outline, and every question cites the 2026 NEC section, or the source it comes from. For test-day logistics, see the Master exam day.
