NEC Exam Types Explained: Journeyman, Master, and More

Types of Electrical Licensing Exams

Electrical licensing varies by state, but most states base their exams on the National Electrical Code. Here’s a breakdown of the common exam types.

Journeyman Electrician

The Journeyman Electrician exam is the most common electrical licensing exam. It typically requires:

• Experience: 4 years (8,000 hours) of supervised electrical work
• Exam focus: General NEC knowledge across all chapters, with emphasis on Chapters 2-4
• Question count: Usually 80-100 questions
• Time limit: Typically 4-5 hours
• Passing score: 70-75% depending on state

What to Expect

Journeyman exams cover a broad range of NEC topics. You’ll see questions on:

• Conductor sizing and ampacity
• Branch circuit and feeder requirements
• Grounding and bonding
• Overcurrent protection
• Wiring methods and materials
• Basic load calculations

Master Electrician

The Master Electrician exam is a step up from the Journeyman level:

• Experience: Typically 2+ years as a licensed Journeyman
• Exam focus: More advanced calculations, special occupancies, and business knowledge
• Question count: Usually 80-100 questions
• Difficulty: Higher than Journeyman with more calculation-intensive questions

Additional Topics

Master exams include everything on the Journeyman exam plus:

• Advanced load calculations (Article 220)
• Voltage drop calculations
• Special occupancies (Chapter 5)
• Special equipment (Chapter 6)
• Emergency and standby systems (Chapter 7)
• Business and law questions (state-specific)

Residential Electrician

Some states offer a Residential Electrician license for those who work exclusively on dwelling units:

• Scope: Limited to one-family and two-family dwellings
• Focus: NEC requirements specific to residential installations
• Key articles: 210, 220, 230, 250, 310, 334, 422

Electrical Inspector

Electrical inspectors need a different perspective on the NEC:

• Focus: Code interpretation and enforcement
• Organisation: Often through ICC (International Code Council)
• Types: Residential Inspector (E1) and Commercial Inspector (E2)

Electrical Contractor

Some states require a separate contractor’s license:

• Additional content: Business law, estimating, project management
• NEC focus: Similar to Master Electrician level
• State-specific: Requirements vary significantly
