Master & Journeyman Electrician Exam Prep Guide

Pass your Journeyman or Master Electrician licensing exam with confidence.

This comprehensive exam prep guide from Practicing Engineers Network covers everything you need to succeed — from exam strategy and NEC code review to electrical calculations and four full-length practice exams.

What's inside:

• Exam overview for both Journeyman and Master licensing — exam format, topic weighting, scoring requirements, and what to expect on exam day

• Chapter-by-chapter NEC 2023 review covering Articles 100, 110, 210, 215, 220, 230, 240, 250, 300–400, 430, 440, 517, 700–702, and more

• Electrical theory and calculations: Ohm's Law, Watt's Law, three-phase power, transformer sizing, voltage drop, residential and commercial load calculations, motor circuit sizing, and fault current analysis

• Special occupancies: hazardous locations (Class I/II/III), health care facilities, emergency and standby systems, low-voltage wiring

• 320 practice exam questions across four complete exams — two Journeyman (80 questions each) and two Master Electrician (80 questions each) — all keyed to the 2023 NEC with full answer explanations and code references

• Six appendices: Formula Reference Sheet, NEC Demand Factor Tables, Conductor Ampacity Tables, NEC Quick Reference Tables, Exam-Day Checklist, and Glossary of Key Terms

Written by working engineers who have used this material in real field applications, not just in classrooms. Every answer key includes the NEC article number so you can verify the answer and learn the code at the same time.

Whether you are sitting for your first Journeyman exam or upgrading to a Master license, this guide gives you the knowledge, the calculations, and the practice you need.
