The Wyoming Master Electrician Guide

What Is the Wyoming Master Electrician License?

The master electrician license verifies that an electrician can design, install, alter and repair electrical systems in full compliance with the National Electrical Code (NEC) — and can take responsibility for that work. In Wyoming, state electrical licensing is administered by the Department of Fire Prevention and Electrical Safety, and the technical examination is the national ICC 701 Standard Master Electrician exam, delivered by Pearson VUE.

Wyoming's master license is the ceiling of a field-license ladder that runs apprentice to journeyman to master. It is also tied to employment: a master in Wyoming must be employed by a Wyoming electrical contractor and serve as the contractor's master of record — the licensed master who takes technical responsibility for the contractor's work. The license is not a certificate you hang on the wall; it is a role you fill inside an operating contracting business.

Eligibility: 8 Years, 16,000 Hours, and 576 Classroom Hours

Wyoming sets one of the highest experience bars in the country for the master exam:

• Total experience: 8 years and 16,000 hours of electrical experience.
• Journeyman tenure: the experience must include 4 years as a licensed journeyman — Wyoming's journeyman license is the ICC 385 exam (80 questions, 4 hours, 70% to pass), from the same ICC outline family as the master exam.
• Classroom education: 576 hours of related classroom education, documented alongside your field hours.
• Master of record: masters must be employed by a Wyoming electrical contractor as the contractor's master of record.
• Application: the Department of Fire Prevention and Electrical Safety reviews your verified documentation before granting exam eligibility. Contact the Department for current eligibility requirements and fees.

Exam Format: The ICC 701 Standard Master Electrician

The Wyoming Master Electrician exam is the ICC 701 Standard Master Electrician examination — the same national exam family used across states that license masters through ICC. Delivered by Pearson VUE, it is one continuous technical session:

• Length: 100 scored questions spanning the full ICC master outline — general knowledge and plan reading, services, feeders, branch circuits, wiring methods, equipment, control devices, motors and generators, and special occupancies.
• Time: 300 minutes — five hours. That is about 3 minutes per question, so this is as much a stamina and navigation test as a knowledge test.
• Pass line: 75%. On the ICC master exam the cut is 75%, while most other trades exams pass at 70% — Wyoming's master bar is set higher on purpose.
• Open book: the NEC (2023 exam bank) and Ugly's Electrical References are permitted, and Wyoming also allows optional Ferm's or Tom Henry code indexes and the NEC Handbook.
• Vendor: scheduling and delivery run through Pearson VUE under the state electrical licensing program.

Open-Book Rules: The NEC in Your Hands for Five Hours

The ICC 701 exam is open book, and Wyoming's permitted list is one of the most generous in the country: the NEC, Ugly's Electrical References, optional Ferm's or Tom Henry code indexes, and the NEC Handbook. Five hours with the code removes the need to memorize — but it means the test separates candidates on navigation speed and endurance. Candidates who pass know the chapter map cold — grounding in Article 250, services in Article 230, wiring methods in Chapter 3, motors in Article 430 — and can find the right table before the clock's pressure builds. A quick-reference index like Ferm's or Tom Henry is only an advantage if you have drilled with it; practice with the exact stack you will carry on exam day.

A note on editions: the exam bank references the NEC 2023, while the field code enforced on new installations in Wyoming moved to the NEC 2026 effective July 1, 2026. Do not mix them up — prepare with the NEC 2023 for the exam and confirm the current edition and reference list with the Department when you register.

Official Subject Areas (Wyoming ICC Blueprint)

Wyoming weights the national ICC 701 outline for its own license. Study time should track these weights:

The pattern is unmistakable: Wiring Methods & Materials (26) and Branch Circuits & Conductors (19) alone are 45 of the 100 questions — nearly half the exam — and adding Equipment & Devices (13) brings the top three to 58. Feeders and Control Devices are tested, but lightly. Master the heavy columns first; that is where the 75% pass line is won.

Journeyman to Master: The Same Outline Family

If you hold a Wyoming journeyman license, you already know the ICC style. Wyoming's journeyman exam is the ICC 385 — 80 questions, 4 hours, 70% to pass — built on the same ICC outline family as the master exam. The step up to the ICC 701 master exam adds length (100 questions, 5 hours), raises the pass line to 75%, and weights the blueprint harder toward Wiring Methods and Branch Circuits. Your journeyman study habits transfer; the depth and the stamina do not — build both deliberately.

Fees & Retakes

• License fee: $200 for the initial master license, set by the state electrical licensing program.
• Exam fee & retakes: set by Pearson VUE and the Department for the current exam window; if you fall short of the 75% pass line you re-sit the full 100-question ICC 701 exam — there is no partial credit. Contact the Wyoming Department of Fire Prevention and Electrical Safety for current fees and eligibility requirements.
• Vendor: the ICC 701 exam is delivered by Pearson VUE; confirm the current bulletin at wsfm.wyo.gov/electrical-safety/licensing.

A 75% pass line on a 100-question, five-hour, open-book exam is a stamina problem as much as a knowledge problem. Training for it means full-length timed runs — not 20-question warm-ups — so that hour four and five feel like hour one.

How to Prepare

1. Confirm your eligibility and employment plan. Verify your 8-year / 16,000-hour documentation (including 4 years as a licensed journeyman and 576 classroom hours) with the Department of Fire Prevention and Electrical Safety, and confirm your master-of-record employment with a Wyoming contractor.
2. Get the NEC 2023 and your reference stack. Buy the soft-bound NEC 2023 used on the exam bank, plus Ugly's. If you plan to use a Ferm's or Tom Henry index or the NEC Handbook, buy them now and practice with the full stack.
3. Learn the chapter map and the ICC outline. Know where each of the nine blueprint subjects sits in the code before you open a practice question — wiring methods, branch circuits, services, equipment, motors, special occupancies.
4. Drill the heavy columns first. Wiring Methods & Materials (26), Branch Circuits & Conductors (19) and Equipment & Devices (13) are 58 of 100 questions. Get those to exam-day reliability before touching Feeders or Control Devices.
5. Build five-hour stamina. The exam is 300 minutes at 75% — train with full-length, timed, open-book simulations of the 100-question format at least weekly in the final month, not short drills.
6. Practice code navigation under pressure. At 3 minutes per question, index-first lookup and knowing which article covers which subject is what actually moves your score in hours four and five.

Master Electrician Practice is built for the ICC Standard Master Electrician blueprint: practice questions that cover the same subject outline Wyoming tests — with exact NEC code references — timed simulations of the 100-question, 300-minute open-book format, full NEC theory and an AI tutor. Start with free practice questions to feel the format before you commit.
