What is the passing score and format for the Journeyman Electrician exam?
Most state licensing boards (via PSI, Prometric, or ICC) require a minimum passing score of 70% or 75%. The examination consists of 80 to 100 multiple-choice questions administered over 4 hours (240 minutes). Candidates are permitted to use an approved, indexed copy of the National Electrical Code (NEC / NFPA 70).
Which edition of the National Electrical Code (NEC) is tested?
Testing jurisdictions typically test the 2020 or 2023 edition of NFPA 70, with states progressively adopting the 2026 code cycle. Always verify your specific state licensing board candidate bulletin for the exact adopted NEC edition.
What are the most heavily weighted topics on the Journeyman Electrician examination?
Feeder and branch circuit load calculations (Article 220), grounding and bonding sizing (Article 250, Table 250.66 & 250.122), conductor ampacity adjustment and correction (Table 310.16), and motor branch-circuit short-circuit and ground-fault protective device sizing (Article 430, Table 430.52).
How do you calculate continuous load branch circuit ampacity under the NEC?
Under NEC Article 210.19(A) and 215.2(A), the branch-circuit rating must not be less than the noncontinuous load plus 125% of the continuous load (loads expected to continue for 3 hours or more).
