Master electricians need advanced knowledge of electrical distribution systems, load calculations, equipment installations, and electrical safety. Their professional responsibilities involve understanding how electrical systems are designed, installed, protected, and maintained in accordance with applicable codes.
The Montana Master Electrician examination evaluates knowledge of the National Electrical Code, general electrical trade theory, and major load calculations. Candidates must understand electrical principles, interpret technical requirements, and apply appropriate calculation methods to different installation situations.
This preparation resource focuses on the National Electrical Code, NEC, 2020, published by the National Fire Protection Association as NFPA 70.
Whether you are advancing beyond journeyman-level responsibilities or reviewing knowledge developed through years of electrical experience, 1 Exam Prep supports consistent study and practical preparation for the Montana Master Electrician licensing examination.
The Montana Master Electrician 2020 examination is administered by PSI on behalf of the Montana State Electrical Board.
The examination evaluates advanced electrical knowledge involving the National Electrical Code, electrical theory, and major load calculations.
The examination includes three principal content areas:
The four-hour testing period provides an average of three minutes per question. Efficient code navigation and familiarity with electrical calculation methods are important preparation skills.
Master electrician candidates should understand both general NEC provisions and specialized requirements that apply to particular equipment and installation conditions.
The Montana Master Electrician 2020 PSI examination is an open book test.
Authorized examination materials include the following:
