Modern irrigation and landscape lighting systems rely on electrical components to operate controllers, valves, transformers, timers, and outdoor lighting equipment. Although these systems frequently operate at lower voltages, their installations still require appropriate conductors, power supplies, wiring methods, and electrical protection.

The ICC 253-WY examination focuses on the electrical knowledge associated with lawn sprinkler and landscape lighting installations operating at less than 90 volts. Candidates are tested on electrical definitions, code requirements, practical wiring methods, circuit classifications, and low-voltage transformer fundamentals.

Preparation is centered on two important reference publications: the National Electrical Code (NEC), 2023, and Ugly's Electrical References. These resources provide the electrical code provisions, formulas, technical tables, and definitions that support preparation for the examination.

Whether you are developing your electrical knowledge or reviewing concepts encountered during fieldwork, 1 Exam Prep helps you approach your studies with a clear focus on the subjects included in the Wyoming 253-WY examination.

Exam Details

The Wyoming ICC Low-voltage Lawn Sprinkler and Landscape Lighting Technician examination, identified by examination code 253-WY, is part of the International Code Council's Contractor/Trades examination program.

The examination is administered through Pearson VUE. Wyoming electrical technician licensing is managed by the Wyoming State Fire Marshal's Department of Fire Prevention and Electrical Safety.

  • Exam Name: Wyoming Low-voltage Lawn Sprinkler and Landscape Lighting Technician
  • Exam Code: 253-WY
  • Examination Organization: International Code Council (ICC)
  • Testing Provider: Pearson VUE
  • Question Format: Multiple choice
  • Number of Questions: 30
  • Time Limit: 1 hour and 30 minutes
  • Exam Type: Open book
  • Primary Code Reference: National Electrical Code, 2023
  • Additional Reference: Ugly's Electrical References
  • Product Format: Online practice questions
  • Online Access: 3 months

The official ICC examination outline identifies four primary content areas:

  • General Knowledge of Electricity and Code Definitions: 40%
  • Wiring Methods for Circuits Operating at Less Than 90 Volts: 33%
  • Circuits and Conductors for Class 2 and Class 3 Circuits: 20%
  • Low-voltage Transformers: 7%

General electrical knowledge and code definitions account for 40% of the examination. Understanding electrical terminology, fundamental circuit relationships, and the structure of the NEC is therefore an important preparation priority.

Wiring methods for circuits operating at less than 90 volts represent another 33%. Together, these two categories account for 73% of the examination, emphasizing the importance of electrical fundamentals and practical installation knowledge.

With 90 minutes to complete 30 questions, candidates have an average of three minutes per question. Familiarity with electrical terminology and efficient NEC reference navigation can help make better use of that time.

Open Book Test

The Wyoming ICC Low-voltage Lawn Sprinkler and Landscape Lighting Technician 253-WY examination is an open book test. Candidates may consult authorized reference publications in accordance with ICC examination procedures.

The designated examination references include the 2023 National Electrical Code and Ugly's Electrical References. ICC also recognizes certain electrical code indexes and the NEC Handbook among its permitted electrical examination references.

An open-book examination requires more than the ability to search through a code book. Candidates must understand the electrical situation presented, recognize which requirements apply, and locate the relevant information efficiently.

For example, a question concerning irrigation control wiring may involve conductor protection, circuit classification, or an appropriate wiring method. A landscape lighting question may require understanding transformer operation or the electrical characteristics of a low-voltage circuit.

Effective open-book preparation includes:

  • Learning the organization of the 2023 National Electrical Code.
  • Reviewing electrical terminology and NEC definitions.
  • Practicing basic electrical calculations.
  • Studying wiring methods for circuits below 90 volts.
  • Understanding Class 2 and Class 3 circuit requirements.
  • Reviewing conductor insulation and cable identification.
  • Studying low-voltage transformer fundamentals.
  • Practicing reference lookups while answering questions.

Consistent practice with the NEC helps develop the ability to identify the correct article, review its requirements, and apply those provisions to a technical question.

Licensing Steps

Wyoming low-voltage electrical technician licensing is administered by the Wyoming State Fire Marshal's Department of Fire Prevention and Electrical Safety.

The state's lawn sprinkler low-voltage classification is identified as LV-LS, covering authorized low-voltage lawn sprinkler systems under 90 volts.

  1. Identify the Appropriate License: Review the LV-LS lawn sprinkler classification and the work it authorizes.
  2. Review State Qualifications: Understand the qualifying experience and licensing requirements.
  3. Gain Relevant Work Experience: Complete qualifying low-voltage lawn sprinkler electrical work.
  4. Document Your Experience: Gather acceptable employment verification showing the nature and duration of the work performed.
  5. Create a State Licensing Account: Use Wyoming's eLicense system to begin the applicable licensing process.
  6. Complete the Application: Submit the required identification, experience documentation, and application information.
  7. Obtain Examination Eligibility: Receive the necessary approval before scheduling the ICC examination.
  8. Prepare for the Examination: Review electrical theory, wiring methods, Class 2 and Class 3 circuits, and transformers.
  9. Schedule the 253-WY Examination: Arrange testing through Pearson VUE after eligibility approval.
  10. Complete Licensing: Submit passing examination documentation and satisfy Wyoming's remaining licensing requirements.

Technical preparation and documented field experience are both important parts of professional low-voltage electrical work. Studying the NEC reinforces the electrical requirements that support safe and properly installed irrigation and landscape lighting systems.

State Requirements

Wyoming recognizes the LV-LS Low-voltage Lawn Sprinkler Technician classification for qualifying electrical work associated with lawn sprinkler systems under 90 volts.

Important state licensing information includes:

  • License Classification: LV-LS Low-voltage Lawn Sprinkler.
  • Licensing Authority: Wyoming State Fire Marshal's Department of Fire Prevention and Electrical Safety.
  • Authorized Work: Low-voltage lawn sprinkler systems under 90 volts.
  • Listed Experience Requirement: 80 hours for the LV-LS classification.
  • Examination: Wyoming ICC Low-voltage Lawn Sprinkler and Landscape Lighting Technician 253-WY.
  • Work Verification: Acceptable documentation of qualifying employment and experience.
  • Contractor Employment: Technicians performing regulated low-voltage work must be employed by an appropriately licensed Wyoming low-voltage or limited electrical contractor.
  • Code Compliance: Electrical work must follow applicable NEC provisions and Wyoming electrical safety requirements.

The LV-LS classification is a limited electrical credential. It does not authorize unrestricted work on electrical services, feeders, or other installations outside the classification's permitted scope.

Understanding the distinction between low-voltage equipment and higher-voltage supply wiring is important when working with irrigation controllers and landscape lighting power supplies.

Electrical work outside a technician's authorized classification requires the appropriate licensing and supervision.
