Open Book Test

The 474_WY exam is an open book test. Open book is a benefit only when you’re already comfortable using your references quickly. With 40 questions in 2 hours, you typically have about three minutes per question on average—and some items will take longer than others.

A strong open-book strategy for this exam comes down to three habits:

• Spot the “code target” fast: Identify whether the question is about equipment/motor connections, branch circuits and overcurrent protection, wiring methods, grounding/bonding, or definitions and calculations.
• Confirm, don’t wander: Go directly to the NEC location that governs the scenario, confirm the rule, and avoid over-reading unrelated sections.
• Protect your pace: If a question becomes a time trap, mark it mentally, make your best supported choice, and keep moving so you don’t sacrifice easier points later.

This is why prep must be more than reading. You want repeated practice interpreting question wording, identifying the topic, and navigating to the correct NEC location efficiently—because that’s the skill open-book exams are designed to measure.

Licensing Steps

Wyoming’s ICC Contractor/Trades exam bulletin explains that before scheduling an exam, you must first make a license application with the Wyoming Department of Fire Prevention and Electrical Safety. If your application is satisfactory, ICC is notified of your eligibility to test. After you receive approval, you may schedule your examination through Pearson VUE.

Many applicants move through the process in this general order:

1. Confirm the correct limited technician category for your scope (water wells and irrigation systems).
2. Document your work experience using Wyoming-accepted work verification methods.
3. Submit your application through the Wyoming electrical licensing process.
4. Receive eligibility approval to test once your application is accepted.
5. Schedule and pass the 474_WY exam through Pearson VUE.
6. Upload your pass letter to your licensing portal account and complete the payment step to activate the license.

This Online Exam Prep supports the exam step by helping you prepare in an exam-aligned way—so you’re training the same skills you’ll need during the timed session.

State Requirements

Wyoming’s electrical licensing information lists the limited technician category for this scope as:

• LM-W: Electrical work for water well and irrigation systems limited to electrical work on the load side of the equipment disconnect (4,000 hours).

Wyoming also states that any technician performing low voltage work in Wyoming must be employed at all times by a low voltage/limited contractor who carries a current Wyoming low voltage/limited contractor’s license.

For licensing completion after passing the exam, Wyoming’s licensing information explains that once the applicant has passed the examination, the applicant uploads the pass letter into the eLicense portal account and pays the initial license fee of $100.00. Wyoming also states the technician license is valid for 3 years, renewing on July 1 of every third year, with a $50.00 renewal fee.

Wyoming also states that it adopts the National Electrical Code without modification and that license examinations are based on the current edition of the NEC—supporting why NEC 2023 is the correct core reference for your 474_WY preparation.

Reference Books

• National Electrical Code, NEC, 2023
  Your primary exam reference. Use it to confirm requirements related to branch circuits and overcurrent protection, wiring methods, grounding and bonding, and the rules that apply to equipment and motor connections on the load side of the disconnect.
• Ugly's Electrical References
  A compact electrical companion reference used for quick fundamentals and common electrical relationships that support theory and basic calculation-style questions.

Test Information and Study Materials

The 474_WY content outline tells you exactly where to focus your time. If you want the most efficient study plan, study in proportion to the weighting and build your skills from “foundation” to “application.”

Here’s how to turn each content area into practical preparation using NEC 2023 and Ugly’s:

• Equipment and Motors (Load Side of Disconnect to Equipment) — 28%
  This is the largest portion of the exam. Treat it as your anchor topic. Study by practicing how to interpret equipment and motor scenarios, then confirm the controlling NEC requirement quickly. Your goal is to build a repeatable navigation habit: identify the equipment/motor issue, locate the governing NEC section, confirm the rule, and answer with confidence.
• General Knowledge, Theory, Basic Load Calculations, and Definitions — 20%
  Many candidates underestimate this section, but it’s a major driver of your score. Definitions can change how a question must be interpreted, and calculation questions reward careful, step-by-step thinking. Use the NEC for definitions and code-based requirements, and use Ugly’s to keep your fundamentals sharp so basic electrical concepts don’t slow you down.
• Branch Circuits, Overcurrent Protection, and Conductors (Load Side of Disconnect to Equipment) — 20%
  Expect questions that test whether you can read the scenario carefully and apply the correct requirement for the situation described. A useful study habit is to highlight the “conditions” in each question (equipment type, installation condition, and what is being asked) before you look anything up. Then use the NEC to confirm the rule that matches those conditions.
• Wiring Methods and Conductors (Load Side of Disconnect to Equipment) — 17%
  Wiring method questions can become time sinks if you don’t have a navigation plan. Study by practicing scenario questions and training yourself to identify the wiring method “trigger” immediately—then confirm the permitted/required installation rule in the NEC without drifting into unrelated sections.
• Grounding and Bonding — 15%
  Grounding and bonding questions often test understanding rather than memorization. The best prep is to focus on purpose and application: what the question is trying to protect against and what the NEC requires in that situation. Practice confirming the requirement quickly so you can answer accurately without overthinking.

A simple drill that improves open-book speed: whenever you miss a practice question, write down the NEC location that supports the correct answer. Later, find that same location again without notes. This repetition builds navigation confidence—and navigation is one of the biggest advantages you can develop for a timed open-book exam.
