Open Book Test

The Wyoming 253_WY exam is an open book exam. That means your score is strongly influenced by how well you can navigate your references under time pressure.

Open book testing rewards two skills at the same time:

• Understanding the rule (what the requirement means in the field)
• Finding the rule fast (knowing where it is in the NEC and how to confirm it quickly)

That’s exactly why a highlighted and tabbed set matters. When you can find definitions, wiring method requirements, and Class 2/Class 3 circuit rules quickly, you spend less time searching and more time answering.

Licensing Steps

Wyoming low-voltage technician licensing is handled through the state’s electrical licensing authority within the Department of Fire Prevention and Electrical Safety. While your exact path depends on your category and work history, the process commonly follows these steps:

1. Choose the correct low-voltage license category for your work.
   Wyoming recognizes multiple low-voltage categories under 90 volts, including a category for lawn sprinkler systems under 90 volts (LV-LS). If your work includes landscape lighting along with irrigation control, make sure the category you pursue matches your scope of work.
2. Meet the experience requirement and document your work history.
   Wyoming’s low-voltage technician licensing by examination is tied to verified experience in the portion of the electrical wiring industry covered by your license type. Work experience is documented through acceptable verification forms such as notarized letters or the state work verification form.
3. Submit your application for approval to test.
   After you apply, your eligibility is reviewed. Once approved, the exam administrator is notified so you can schedule your exam.
4. Prepare using the approved references (this book package).
   Study the NEC and Ugly’s with a focus on the exam content areas. Practice timed lookups so open-book navigation becomes automatic.
5. Schedule and take the ICC 253_WY exam.
   The exam is open book, 30 multiple-choice questions, with a 1 hour 30 minute time limit.
6. Complete any remaining licensing requirements and maintain your license.
   Follow Wyoming licensing renewal requirements and keep documentation current as required by the state.

State Requirements

Wyoming’s electrical licensing information outlines what qualifies a person as a low-voltage technician and lists the low-voltage categories available. Wyoming describes a low-voltage technician as a person licensed by the Department with verified experience and technical knowledge to install and supervise installation of electrical equipment associated with the type of low-voltage license held, in accordance with the National Electrical Code and applicable ordinances and regulations.

Key Wyoming points that matter for candidates pursuing a lawn sprinkler and landscape lighting technician path include:

• Low-voltage categories under 90 volts
  Wyoming lists multiple low-voltage licenses, including LV-LS for low-voltage work for lawn sprinkler systems under 90 volts.
• Experience verification
  Work experience must be documented through acceptable proof such as notarized letters from employers or the state’s employment verification process.
• Licensing by examination
  Technician licensing in Wyoming is obtained through examination, and applicants typically must be approved before scheduling their test.
• Contractor employment requirement for low-voltage work
  Wyoming notes that technicians performing low-voltage work in the state must be employed at all times by a low voltage/limited contractor holding a current Wyoming contractor license.

Because licensing requirements can involve both the technician license type and contractor relationship requirements, it’s smart to align your exam prep with your real scope of work. This book package helps you focus on the code knowledge and reference navigation expected for the 253_WY exam content.

Reference Books

• National Electrical Code, NEC, 2023
  The primary code reference for the exam. Use it to master definitions, general requirements, wiring methods, Class 2 and Class 3 circuit requirements, and the NEC sections that guide low-voltage installations under 90 volts.
• Ugly’s Electrical References
  A compact electrical reference used by many technicians for fast access to commonly needed tables, formulas, wiring configurations, conduit and ampacity references, transformer/control circuit information, and conversion tables that support calculations and field decision-making.

Test Information and Study Materials

To prep efficiently for ICC 253_WY, study the way you’ll test: with your books open, using the content outline as your roadmap, and practicing fast lookups.

Here’s a practical way to use your highlighted and tabbed references to prepare:

• Build a “definitions first” habit.
  Because a large portion of the exam is general knowledge and code definitions, train yourself to confirm vocabulary and scope language quickly in the NEC. Many missed questions come from mixing up similar terms or overlooking a definition detail.
• Drill wiring methods for low-voltage circuits under 90 volts.
  Focus on how wiring is allowed to be run, supported, protected, and installed in typical irrigation and lighting conditions. Your tabs make it easier to return to the same sections repeatedly until the layout becomes familiar.
• Practice Class 2 and Class 3 circuit questions with a repeatable method.
  When you see Class 2/Class 3 language, your approach should be consistent: identify the circuit type, identify the conductor/cable method, confirm requirements, then choose the answer that matches the code’s wording and intent.
• Make transformers “automatic.”
  Transformer questions are a smaller slice of the exam, but they’re often high-confidence points if you know where to confirm transformer basics and low-voltage supply rules.
• Use timed mini-sessions.
  Instead of one long study block, do several 15–25 minute timed drills where your only goal is to locate answers quickly. This builds speed without burnout.

Why highlighted and tabbed books help so much in open-book testing: you reduce the mental load of searching. When you already know where core topics live, you spend your time applying the rule—not hunting for it.
