Built for the exam you are taking
Industrial, Maintenance, and Specialty
- Industrial: 70 questions · 180 minutes
- Maintenance/Specialty: 50 questions · 120 minutes
- Specialty categories require additional focused preparation
Check the fit before ordering: JCR is strongest for the standard, industrial, and maintenance NEC work. Specialty alarm/communications candidates must add category-specific preparation.
Exactly what is included
- 152-page printed manual: six-week roadmap, Code navigation, calculations, guided practice, and answer keys.
- 100 video lessons totaling 21 hours: self-paced instruction you can pause, replay, and review.
- 500+ practice questions: paper practice, explanations, and timed digital mock-exam work.
- Permanent Code-book tabs: faster access to heavily tested NEC articles, tables, and sections.
JCR’s manual and videos build the 2020 NEC and technical foundation shared across Hawaii’s electrical exams. Use the PSI outline for every category-specific subject.
The exam Code book and other official references are sold separately.
Exam facts, books, and official sources
PSI currently supplies the 2020 NEC at the testing center. Use your own 2020 NEC for study; JCR tabs are study aids only for this path. Follow the test-center rules rather than bringing your prepared book.

Common questions before you order
Can I bring my tabbed NEC to the Hawaii exam? The current PSI bulletin says the test center supplies the 2020 NEC. Use your own book and tabs for study only.
