Mississippi regulates statewide commercial electrical contracting through the Mississippi State Board of Contractors. Electrical is a major commercial contractor classification covering the installation, repair, alteration, addition to, and design of electrical wiring, fixtures, appliances, apparatus, raceways, conduit, and electrical systems that generate, transmit, transform, or use electrical energy.

The Mississippi testing program uses the title Master Electrician for the state-specific electrical trade examination. The examination bulletin describes its scope as unlimited electrical work. Mississippi applicants seeking the major Electrical contractor classification may choose between the MSBOC Master Electrician state-specific trade examination and the NASCLA Accredited Trade Examination for Electrical Contractors.

This package is based on the 2026 National Electrical Code and provides current-code instruction, electrical theory review, advanced calculation practice, NEC navigation training, and organized master-level preparation. The current Mississippi state-specific Master Electrician examination remains based on the 2020 National Electrical Code. Candidates taking the current state-specific test should therefore also prepare extensively with the 2020 NEC required by the official examination program.

Candidates choosing the NASCLA Electrical examination currently have a different reference structure. The NASCLA examination permits the 2020 or 2023 National Electrical Code or corresponding NEC Handbook among its authorized references. The 2026 NEC included with this package provides newer-code education but is not currently listed as the NEC reference for either Mississippi electrical trade-exam pathway.

The included 2026 NEC provides a current learning platform for services, feeders, branch circuits, grounding and bonding, conductors, overcurrent protection, raceways, boxes, wiring methods, motors, electrical power, lighting, special occupancies, special equipment, low-voltage systems, fire alarm systems, and other advanced electrical subjects.

The NEC tabs help students organize frequently used articles, definitions, and tables while developing faster navigation habits. The Master Electrician Study Guide provides advanced trade-focused review, while the Calculations Study Guide emphasizes services, feeders, conductor sizing, motors, transformers, voltage drop, raceway fill, box fill, load calculations, and electrical power.

Flash cards provide active-recall practice for formulas, terminology, definitions, and important electrical concepts. The online course adds instructor-led NEC education, simulated practice examinations, a structured NEC overview, live instructional videos, and recorded lessons that can be reviewed around a working electrician’s schedule.

Exam Details

Mississippi applicants pursuing the major Electrical contractor classification have two trade-examination options. They may take the MSBOC Master Electrician state-specific examination or the NASCLA Accredited Trade Examination for Electrical Contractors.

The current Mississippi state-specific Master Electrician examination contains 80 questions and allows three hours for completion. Candidates must earn a minimum score of 70 percent to pass.

General Electrical Knowledge contains six questions. Candidates should understand electrical theory, terminology, calculations, practical trade concepts, voltage, current, resistance, electrical power, and fundamental master-level electrical principles.

Services, Feeders, and Branch Circuits contain 10 questions. Preparation should include service conductors, service equipment, feeder loads, branch circuits, conductor sizing, disconnecting means, grounding, and overcurrent protection.

Grounding and Bonding contains seven questions. Candidates should review grounding electrode systems, grounding electrode conductors, equipment grounding conductors, bonding jumpers, service bonding, separately derived systems, and effective ground-fault current paths.

Conductors and Cables contain 10 questions. Study conductor ampacity, insulation, temperature limitations, adjustment and correction factors, cable applications, terminations, and physical protection.

Raceways and Boxes contain seven questions, while Special Occupancies and Equipment contain another seven. Candidates should understand conduit and raceway systems, boxes, enclosures, fill requirements, support methods, specialized occupancies, and equipment governed by special NEC provisions.

Electrical Power contains six questions and Motors contain six. Candidates should practice single-phase and three-phase calculations, power relationships, motor conductors, overload protection, short-circuit protection, controllers, disconnecting means, and applicable NEC motor tables.

The examination also includes Low Voltage, Lighting, Illuminated Signs, Fire Detection and Alarm Systems, Safety Information, and Overcurrent Protection. These areas combine NEC knowledge with practical electrical installation and safety principles.

The NASCLA electrical option is broader. The current NASCLA Accredited Trade Examination for Electrical Contractors contains 100 questions, requires a score of 75, and allows 270 minutes, or four and one-half hours. Its major categories include Project Design and Management, Safety, Electrical Theory and Principles, General Code Requirements, Wiring and Protection, Wiring Methods and Materials, General Equipment Use, Special Installations, and Communication Systems.

Open Book Test

The Mississippi Master Electrician state-specific examination is an open-book test. Candidates are responsible for bringing the authorized references identified in the current PSI Candidate Information Bulletin.

The current state-specific examination identifies NFPA 70, National Electrical Code, 2020 Edition, as its NEC reference. The examination also permits the applicable OSHA construction regulations and specified editions of Ugly’s Electrical References.

The 2026 NEC included with this package is designed for current-code education and instructor-led study. Candidates taking the current Mississippi state-specific examination should also prepare with the 2020 NEC because the official examination questions are based on that edition.

The NASCLA Electrical examination is also open book. Its current reference list permits the 2020 or 2023 National Electrical Code or NEC Handbook, along with additional approved references covering safety, electrical theory, project management, energy standards, business and project management, and related subjects.

Approved examination references may be highlighted, underlined, and indexed before testing. Permanent tabs are permitted. Temporary tabs such as Post-it notes are not allowed.

References may not contain handwritten notes, and candidates may not bring additional loose or attached papers with approved references. Mississippi candidates should organize their examination books before test day within the PSI rules.

A silent, nonprinting, nonprogrammable calculator may be used during the examination. This is particularly useful for service calculations, feeder loads, conductor sizing, electrical power, motor problems, voltage drop, and other mathematical questions.

The NEC tabs included with this package help students develop navigation habits during preparation. Practice locating services, feeders, branch circuits, grounding and bonding, conductors, raceways, boxes, motors, overcurrent protection, lighting, special occupancies, definitions, and major NEC tables.

An open-book examination still requires preparation. Candidates should identify the subject being tested before beginning a code search. Efficient navigation, technical knowledge, and calculation practice can reduce the amount of time spent searching through references during the official examination.

Licensing Steps

Begin by determining whether the Mississippi major Electrical contractor classification is required for the electrical contracting work your business intends to perform. Commercial contracting work exceeding Mississippi’s applicable licensing threshold requires the appropriate contractor credential.

For commercial work, Mississippi requires a commercial contractor license when the project exceeds $50,000. The Electrical major classification is the statewide commercial classification covering broad electrical contracting work.

Submit the contractor license application to the Mississippi State Board of Contractors before attempting to schedule the required examinations. MSBOC reviews the application and then communicates examination eligibility to PSI.

Identify the qualifying party for the business. The qualifying party is the individual responsible for taking the required examination on behalf of the applicant and must be an owner, officer, member of executive staff, or responsible managing employee who meets MSBOC requirements.

The qualifying party must have the experience, knowledge, and skills necessary to supervise or perform the electrical contracting work for which the business is seeking qualification.

Choose the electrical trade-exam pathway. Mississippi Electrical applicants may take either the MSBOC Master Electrician state-specific examination or the NASCLA Accredited Trade Examination for Electrical Contractors.

Complete the Mississippi Law and Business Management examination. MSBOC requires the Law and Business Management examination for contractor applicants even when a qualifying trade-examination score is accepted through NASCLA or an applicable reciprocity arrangement.

Prepare for the electrical examination using a structured study schedule. Begin with the NEC overview and develop familiarity with definitions, chapters, articles, tables, exceptions, and cross-references.

Use the Master Electrician Study Guide for advanced electrical review. Give consistent attention to services, feeders, branch circuits, grounding and bonding, conductors, raceways, motors, lighting, special occupancies, low-voltage systems, fire alarms, safety, and overcurrent protection.

Use the Calculations Study Guide for repeated mathematical practice. Master-level candidates should be comfortable with electrical power, service loads, feeders, conductor sizing, motors, transformers, voltage drop, box fill, and raceway fill.

Use flash cards for formulas, definitions, terminology, grounding principles, conductor rules, motor requirements, and other technical information that benefits from active recall.

Attend live instructor-led NEC training and use the recorded videos to revisit difficult topics. Complete simulated practice examinations under timed conditions before scheduling the official test.

After completing the required examination process, satisfy the remaining financial, insurance, business-registration, reference, and application requirements established by MSBOC before the contractor license is issued.

State Requirements

Mississippi’s statewide program is primarily a contractor licensing system rather than a separate statewide occupational license for individual Master Electricians. The Mississippi State Board of Contractors administers the major Electrical commercial contractor classification, and its trade examination is called the Master Electrician examination.

The major Electrical classification covers installation, repair, alteration, addition to, and design of electrical wiring, fixtures, appliances, apparatus, raceways, conduit, and systems that generate, transmit, transform, or utilize electrical energy, including electrical systems within plants and substations.

Commercial applicants must identify a qualifying party who takes the required examinations and is responsible for the construction operations associated with the classification. MSBOC permits more than one qualifying party when different individuals qualify different examinations or classifications.

Commercial applicants for a major classification are required to submit a reviewed financial statement prepared by a certified public accountant demonstrating the net worth required by MSBOC. The current requirement for a major commercial classification is at least $50,000 in net worth.

Commercial applicants must also provide proof of general liability insurance meeting MSBOC requirements. Businesses organized as corporations, limited liability companies, or similar registered entities must satisfy applicable Mississippi Secretary of State business-registration requirements.

MSBOC requires reference letters as part of the commercial application process, including a bank or financial-institution reference and additional business references.

The Mississippi Law and Business Management examination is mandatory for contractor applicants. Passing the Master Electrician trade examination or receiving approved trade-exam credit does not remove the Law and Business Management requirement.

Mississippi offers trade-exam reciprocity arrangements with qualifying jurisdictions. Reciprocity applies to waiver of a trade examination rather than automatic issuance of a Mississippi contractor license. Applicants using reciprocity must still complete the Mississippi application process and Law and Business Management examination.

A qualifying party who separates from a licensed contractor must be replaced within the period established by MSBOC to maintain the affected classification. The qualifying party remains an important part of the contractor’s continued qualification to perform electrical work.

Electrical contractors remain responsible for complying with Mississippi contractor licensing law, electrical codes applicable to the project, permits, inspections, local requirements, safety standards, and other laws governing construction and electrical installations.
