Exam Details

The Mississippi Transmission and Distribution Lines contractor examination is administered by PSI after the Mississippi State Board of Contractors establishes the candidate’s eligibility. Applicants must submit the appropriate contractor license application and receive testing authorization before scheduling an examination appointment.

The trade exam evaluates knowledge of underground and overhead electrical transmission and distribution systems. Candidates should be prepared for technical questions involving transformers, line construction, electrical theory, safety procedures, grounding, conductors, service installations, poles, structures, and supply-station equipment.

The examination content includes the following primary knowledge areas:

• Transformers: Transformer types, ratings, connections, operation, grounding, protection, installation, maintenance, and related electrical calculations.
• Electrical Knowledge: Voltage, current, resistance, power, circuits, electrical theory, formulas, terminology, and the operation of common electrical equipment.
• Conductors: Conductor materials, sizing, ampacity, insulation, identification, splicing, installation, sag, tension, handling, and protection.
• Overhead Lines: Poles, crossarms, insulators, conductors, hardware, clearances, supports, guying, installation procedures, maintenance, and safe work practices.
• Underground Lines: Direct-buried cables, ducts, raceways, trenches, pulling methods, splices, terminations, clearances, protection, and underground installation procedures.
• Equipment and Safety: Personal protective equipment, tools, lifting, rigging, fall protection, electrical hazards, OSHA requirements, line-clearance procedures, and safe work methods.
• Grounding Methods: Grounding electrodes, bonding, system grounding, equipment grounding, grounding conductors, connections, and utility grounding practices.
• Service Drops and Laterals: Overhead service drops, underground service laterals, attachment points, clearances, conductors, connections, and installation requirements.

• Electric Supply Stations: Transformers, switches, circuit breakers, capacitors, metering devices, grounding, protective equipment, and station safety.

The examination may include questions developed from the listed references, practical trade knowledge, and accepted electrical-industry practices. Candidates should understand the underlying principles rather than depending entirely on locating each answer during the test.

The Mississippi State Board of Contractors determines the examinations assigned to each applicant. A separate Mississippi Law and Business Management examination may also be required. This package contains the technical books associated with Transmission and Distribution Lines preparation and does not include the Mississippi business and law reference.

Open Book Test

The Mississippi Transmission and Distribution Lines contractor examination is an open-book test. Candidates may bring authorized references into the testing center, subject to PSI’s current rules regarding titles, editions, preparation, and book condition.

Approved references may be highlighted, underlined, and indexed before the examination. Permanent tabs are generally permitted. Temporary tabs, removable notes, loose papers, unauthorized inserts, and attached study sheets are not allowed. Candidates may not write in their books during the examination.

An open-book format does not eliminate the need for preparation. Candidates must identify the subject of a question, select the correct reference, find the applicable section, interpret the information, and choose an answer within the available testing time.

Questions involving utility clearances, overhead lines, underground lines, supply stations, worker safety, and grounding may lead to the National Electrical Safety Code. Questions involving services, conductors, grounding and bonding, overcurrent protection, equipment, and wiring methods may involve the National Electrical Code edition designated by PSI.

Construction-safety questions may require 29 CFR Part 1926. Questions involving practical linework, transformers, conductors, poles, structures, rigging, underground systems, and field procedures may lead to Lineman’s and Cableman’s Handbook.

Ugly’s Electrical References can support quick review of formulas, conductor information, calculations, conversions, electrical symbols, grounding data, and other frequently used electrical information.

Candidates should practice with the same approved editions they plan to bring into the testing center. Familiarity with each reference’s index, table of contents, chapter arrangement, code structure, diagrams, formulas, and technical language can make navigation more efficient.

The current Mississippi PSI list identifies NEC 2020 for this exam. Because this package contains NEC 2023, candidates should obtain the currently approved NEC edition separately unless PSI updates its reference list before the scheduled examination.

State Requirements

The Mississippi State Board of Contractors regulates commercial contractors, residential contractors, roofers, and specialty contractor classifications. Transmission and Distribution Lines is a tested specialty classification.

The classification involves the installation, replacement, alteration, and repair of transmission lines on or off public rights of way. It covers underground and overhead electrical transmission lines, pole erection, guying systems, tower-line erection, street lighting, and outside lighting of all voltages.

The scope also includes underground systems, ducts for signal communication and similar installations, transformers, circuit breakers, capacitors, primary metering devices, and related equipment.

Applicants must submit the appropriate contractor license application before testing. The Board reviews the requested classification, qualifying-party details, business information, experience, insurance, and supporting documentation before establishing examination eligibility.

Each applicant must designate a qualifying individual. The qualifying individual completes the examinations assigned to the company and must maintain the relationship with the licensed business required by the Board.

Documentation may be required to establish ownership, officer status, employment, or another accepted relationship between the qualifying individual and the contractor applicant. The Board determines whether the submitted information meets its requirements.

PSI administers the contractor examinations, but the Mississippi State Board of Contractors retains authority over eligibility, classification approval, qualifying-party requirements, examination assignments, and license issuance.

Passing the Transmission and Distribution Lines examination does not automatically issue a contractor license. Applicants must satisfy all applicable application, business, insurance, experience, documentation, qualifying-party, examination, and Board-review requirements.

Test Information and Study Materials

Begin preparation by separating the examination into its major subjects. Create focused review sessions for transformers, electrical knowledge, conductors, overhead lines, underground lines, equipment and safety, grounding, services, poles and structures, and electric supply stations.

Use the National Electrical Safety Code to review overhead and underground utility clearances, supply-station requirements, conductor installations, grounding, work rules, and protection of workers and the public.

Use the applicable NEC edition to review services, grounding and bonding, conductors, equipment, wiring methods, and overcurrent protection. Candidates should distinguish between utility-supply rules in the NESC and premises-wiring rules in the NEC.

Use 29 CFR Part 1926 to review fall protection, ladders, excavation, cranes, rigging, material handling, personal protective equipment, electrical hazards, and construction-site safety. Connect each requirement to practical linework involving poles, towers, trenches, cables, and heavy equipment.

Use Lineman’s and Cableman’s Handbook for transformer systems, conductor installation, overhead construction, underground cables, poles, structures, rigging, grounding, service installations, tools, and maintenance procedures.

Use Ugly’s Electrical References for formulas, calculations, unit conversions, conductor information, electrical symbols, grounding data, and quick-reference tables. Practice completing calculations without spending unnecessary time searching through unrelated sections.

Complete practice questions under timed conditions. Identify the topic before selecting a reference, then use the index, code structure, chapter headings, formulas, and tables to locate the relevant information.

Review every missed question. Determine whether the error involved electrical theory, code interpretation, trade knowledge, calculation, reference selection, or time management. Repeated review can help turn mistakes into targeted study priorities.

How Contractor Exam Prep Helps You Reach Your Goal

Contractor Exam Prep supports Mississippi Transmission and Distribution Lines candidates through organized study guidance, trade-focused review, practice-oriented preparation, and reference-navigation strategies. A coordinated book package provides the technical foundation needed to prepare for a broad electrical trade examination.

Organized preparation helps candidates divide the material into manageable subjects. Transformers, conductors, overhead lines, underground systems, grounding, services, poles, supply stations, electrical theory, and safety can be reviewed separately before being combined through practice questions.

Trade-focused study helps candidates connect code requirements and reference information to the work performed by transmission and distribution contractors. This includes pole setting, conductor installation, transformer connections, cable systems, line clearances, grounding, rigging, services, and safe work practices.

Practice-oriented preparation encourages candidates to apply technical information rather than relying only on passive reading. Working through questions can reveal weak areas, strengthen calculations, improve code interpretation, and build familiarity with linework terminology.

Reference navigation is particularly important for an open-book examination supported by several publications. Candidates should become comfortable using code indexes, tables of contents, handbook chapters, diagrams, formulas, tables, and technical definitions.

No book package guarantees a passing examination score, testing eligibility, or contractor license. Results depend on the candidate’s electrical knowledge, study effort, application status, reference-edition accuracy, navigation skills, time management, and examination performance.
