About the Maryland Master Electrician license
Maryland licenses electricians through the Maryland State Board of Electricians. The Master Electrician is the senior credential. Maryland does not require you to already hold a journeyman license before applying for the master exam — the board requires at least seven years of documented electrical work experience under the direction and supervision of a Maryland-licensed master electrician (or a similarly qualified government employee), and it may credit up to three years of that requirement for completion of an approved, comparable formal electrical training program. You then pass a more demanding exam that adds heavier load-calculation, design, and code-application content. A holder at this level can typically pull permits, supervise journeymen and apprentices, design installations, and serve as the qualifying individual for a licensed contracting business.
The exam is National Electrical Code (NEC) based, because Maryland adopts the NEC as its electrical code. It is normally open book: you may bring a clean, bound copy of the adopted NEC edition. Tabs and highlighting are usually permitted; loose or handwritten notes usually are not — confirm the current rule with the vendor. Plan to tab and index your code book before test day, because the exam is as much a test of how fast you can locate a section as it is of what you have memorized.
Know these scope facts cold, because the exam asks them in plain-language form: the license is held by the individual, not the company; most installations require a permit and inspection before concealment (rough-in) and again at final; you must work within the classification you hold; and performing electrical work without the required license, or beyond your scope, is a violation that can cost you the license and carry civil penalties.
How Maryland licensing works
- Experience: the master license requires at least seven years of documented electrical work under the direct supervision of a Maryland-licensed master electrician (or a similarly qualified government employee). The journeyperson license requires at least four years under the same kind of supervision, or completion of an approved apprenticeship (at least 576 classroom hours and 8,000 work hours) finished within two years of applying — Maryland does not require holding the journeyperson license first as a prerequisite for the master exam.
- Education: the board may credit up to three years toward the seven-year master experience requirement for completing a formal electrical training program comparable to the supervised field experience it substitutes for — it reduces but does not eliminate the field-experience requirement.
- Application: submit the application, fees, and proof of experience (often signed off by a supervising/master electrician or employer) to the board before you are approved to sit.
- Exam vendor: PSI. The passing score is commonly 70 percent — confirm the current cut score, question count, and time limit on the candidate information bulletin.
- Renewal: licenses renew on a 24-month cycle. Maryland requires 10 hours of continuing education for master renewal (5 hours for journeyperson renewal), covering NEC/NFPA and Annotated Code of Maryland content — confirm the current split and any code-update hours with the board.
Before you rely on any value in this guide, confirm the currently adopted NEC edition on the board and PSI bulletin. Ampacities, GFCI/AFCI scope, working-clearance distances, and receptacle-spacing rules all change between editions, and the exam is written to the edition your state has adopted — not necessarily the newest one published.
