Frequently Asked Questions
What is the difference between a Contractor license and a Master license?
A Master Electrician license demonstrates advanced technical knowledge of the NEC, while a Contractor license adds business operation authority — the ability to bid on projects, pull permits, and take legal responsibility for electrical installations. Many states require a Master license before obtaining a Contractor license.
Do I need a Master Electrician license to become a Contractor?
Requirements vary by state. Many states require a Master Electrician license as a prerequisite for the Contractor exam. Some states combine the Master and Contractor exams into a single licensing process. Check your state's specific requirements.
Does the Contractor exam cover business topics?
While the primary focus is on NEC code knowledge, some states include a separate business and law portion covering topics like contract law, lien rights, OSHA regulations, estimating, and business management. The NEC portion has the broadest chapter coverage of any exam type.
Why does the Contractor exam cover communications systems?
Electrical contractors often work on projects that include low-voltage communications, data, and fire alarm systems. Chapter 8 (Communications Systems) carries 4% of the exam weight because contractors need to understand the installation requirements for these integrated building systems.
How should I study for the Contractor exam?
Unlike other exams that let you focus on a few chapters, the Contractor exam requires broad knowledge across all 8 NEC chapters. Start with the heavily weighted chapters (2, 3, 4) then systematically study Chapters 5-8. Use practice exams with contractor-specific weightages to identify your weak areas.
