This online exam prep program helps candidates organize the major references and technical subjects associated with residential electrical contractor preparation. Study areas include the 2023 National Electrical Code, OSHA construction safety, electrical workplace safety, electrical theory, calculations, fire alarm systems, product safety signs and labels, residential building requirements, contractor business and project management, and practical electrical reference navigation.

Passing the NASCLA Residential Electrical Contractor examination does not automatically issue a Mississippi contractor license. Candidates must complete the Mississippi State Board of Contractors application process and satisfy the Board's licensing requirements for the Residential Electrical classification.

Exam Details

The NASCLA Accredited Electrical Examination Program includes three separate electrical trade examinations: Electrical Contractor or Master Electrician, Journeyman Electrician, and Residential Electrical Contractor. Mississippi accepts the NASCLA Residential Electrical Contractor examination through the Mississippi State Board of Contractors.

The NASCLA examination program was developed using occupational analysis and input from electrical subject matter experts. The Residential Electrical Contractor examination focuses on knowledge and skills associated with residential electrical contracting and electrical installations.

Preparation for a residential electrical contractor examination should include subjects such as:

• Residential electrical plans and specifications
• Electrical safety and construction safety
• Electrical theory and principles
• Calculations and practical electrical mathematics
• Testing and troubleshooting
• National Electrical Code requirements
• Residential services and feeders
• Branch circuits and required outlets
• Grounding and bonding
• Overcurrent protection
• Residential wiring methods and materials
• Electrical equipment and appliances
• Fire alarm and signaling systems
• Residential construction requirements
• Contractor business, law, and project management concepts

NASCLA examination applications are submitted through the NASCLA National Examination Database. NASCLA currently lists a $65 examination application fee. Applications are typically processed within seven business days. Once approved, the application is valid for one year, and the candidate currently has up to three opportunities during that eligibility period to take and pass the examination.

After NASCLA approves the candidate's application, PSI provides examination scheduling information. Candidates may schedule the examination at a PSI testing location that offers the exam.

After a candidate passes a NASCLA Accredited Examination, the result is stored in the National Examination Database. Candidates may electronically send an examination transcript to participating licensing agencies, including agencies that accept the applicable electrical examination.

Open Book Test

The NASCLA Residential Electrical Contractor examination is an open book test. NASCLA identifies all three examinations in the Accredited Electrical Examination Program as open-book electrical trade examinations.

Open-book testing makes reference navigation an important part of preparation. Candidates should become comfortable identifying the subject of a question, selecting the appropriate reference, locating the relevant code provision, table, formula, definition, or technical standard, and applying the information correctly.

The 2023 National Electrical Code should be a major focus of preparation. Candidates should practice navigating Article 100 definitions, the NEC index, individual chapters and articles, tables, exceptions, and cross-references. Residential electrical questions can require candidates to connect general electrical requirements with rules that specifically apply to dwelling units, services, feeders, branch circuits, wiring methods, equipment, and special systems.

Reference-navigation practice should be combined with technical understanding. A candidate who understands the electrical concept behind a question can usually identify the correct reference and relevant section more efficiently than someone attempting to search the books without understanding the subject.

During study, practice with realistic electrical questions and use the references to confirm the supporting rule or calculation method. This develops familiarity with both the technical information and the organization of the books.

Licensing Steps

The Mississippi State Board of Contractors administers the Residential Electrical contractor license. Passing the NASCLA Residential Electrical Contractor examination can satisfy an accepted trade examination component, but candidates must still complete Mississippi's licensing process.

1. Identify the Mississippi Residential Electrical classification. This classification covers installation, maintenance, and repair of residential electrical systems and is limited to residential electrical work.
2. Complete the Mississippi residential contractor application. Submit the required application to the Mississippi State Board of Contractors.
3. Document experience in the requested classification. Mississippi's current residential application instructs applicants to demonstrate experience in the classification requested and list at least three completed jobs in that classification.
4. Identify the qualifying party. The qualifying party is the individual responsible for taking required examinations and must meet the Board's applicable employment requirements.
5. Complete the required Law and Business Management examination. Mississippi requires contractor applicants to take the Mississippi Law and Business Management examination.
6. Complete the accepted trade examination requirement. Mississippi accepts the NASCLA Residential Electrical Contractor examination for this pathway.
7. Prepare for the residential electrical examination. Study the NEC, theory, calculations, safety, residential wiring, equipment, fire alarm systems, residential code requirements, and related reference materials.
8. Provide the required application documentation. Submit supporting business, insurance, tax identification, qualifying-party, experience, and other information required by the Board.
9. Complete the licensing process. The Mississippi State Board of Contractors determines whether the applicant has satisfied all requirements before issuing the Residential Electrical license.

State Requirements

The Mississippi State Board of Contractors licenses and regulates contractors within Mississippi. The Board maintains separate commercial and residential contractor classifications, including a specific Residential Electrical classification.

The Residential Electrical classification covers the installation, maintenance, and repair of residential electrical systems. A contractor holding this classification is limited to residential electrical work.

Mississippi law specifically addresses residential subcontractors performing life-safety trades such as electrical, plumbing, HVAC, and mechanical work on residential construction and residential improvement projects. Contractors should obtain the classification required for the type and scope of residential electrical work they perform and comply with applicable state and local permitting requirements.

The Mississippi residential contractor application requires an applicant to demonstrate experience in each requested classification. The current application instructs applicants to list at least three completed jobs involving the classification for which they are applying.

Mississippi also uses a qualifying party system. The qualifying party is the individual responsible for taking required examinations on behalf of the applicant. The qualifying party must be properly associated with the applicant, and the Board requires proof of employment when applicable.

Current Mississippi residential licensing application requirements include proof of general liability insurance. Residential applicants must provide proof of coverage, although the Board does not specify the same minimum liability coverage amount that applies to commercial applicants.

If the applicant has five or more employees, workers' compensation documentation may also be required. Corporations, limited liability companies, and limited liability partnerships must provide the applicable proof of good standing with the Mississippi Secretary of State.

Mississippi's current residential contractor application lists a $50 application fee, which includes one trade classification. An additional fee applies when an applicant requests additional trade classifications. The Mississippi Law and Business Management examination is required but is not treated as a trade classification.

Mississippi requires applicants to complete the licensing process in addition to passing examinations. An examination result alone does not authorize a contractor to perform regulated work. The applicant must receive the applicable license from the Mississippi State Board of Contractors.

Local permitting and electrical requirements may also apply. Contractors should perform work only within the scope of the license held and in accordance with the requirements of the jurisdiction where the project is located.
