Open Book Test

The Wyoming ICC Limited Water Wells and Irrigation Systems Technician 474-WY examination is an open book test. Candidates may consult authorized electrical reference publications in accordance with International Code Council examination procedures.

The examination references include the 2023 National Electrical Code and Ugly's Electrical References.

An open-book examination requires candidates to understand the electrical issue presented and identify the applicable code requirements. Simply having the reference publications available does not replace the need for technical knowledge.

For example, a question involving a water well pump motor may require understanding conductor ampacity, motor ratings, overload protection, equipment grounding, or disconnecting requirements.

Recognizing these relationships helps candidates locate the appropriate NEC article and interpret its provisions.

Effective open-book preparation includes:

  • Learning the organization of the 2023 National Electrical Code.
  • Reviewing electrical definitions and circuit terminology.
  • Practicing electrical theory and basic load calculations.
  • Studying branch circuits and overcurrent protection.
  • Understanding conductor selection and wiring methods.
  • Reviewing grounding and bonding requirements.
  • Studying motors, controllers, and pump equipment electrical connections.
  • Practicing NEC reference navigation and electrical calculations.

The NEC contains both general electrical installation requirements and specialized provisions affecting water well pumps and irrigation equipment. Understanding how these requirements work together supports stronger preparation for code-based questions.

State Requirements

The Wyoming LM-W Limited Water Wells and Irrigation Systems Technician License authorizes specified electrical work involving water well and irrigation systems.

The authorized scope is limited to electrical work on the load side of the equipment disconnect.

Important Wyoming requirements include:

  • License Classification: LM-W Limited Water Wells and Irrigation Systems Technician.
  • Licensing Authority: Wyoming State Fire Marshal's Department of Fire Prevention and Electrical Safety.
  • Qualifying Experience: Two years of relevant electrical work experience.
  • Required Work Hours: 4,000 hours of qualifying experience.
  • Authorized Work: Electrical work for water well and irrigation systems on the load side of the equipment disconnect.
  • Examination: Wyoming ICC Limited Water Wells and Irrigation Systems Technician 474-WY.
  • Experience Documentation: Qualifying work experience must be verified through acceptable documentation.
  • Employment Requirement: Limited technicians performing regulated electrical work must be employed by an appropriately licensed Wyoming low-voltage or limited electrical contractor.
  • Electrical Code Compliance: Electrical installations must comply with the applicable National Electrical Code and Wyoming requirements.

The LM-W classification does not provide unrestricted authorization to perform all electrical installations. Its scope is specifically related to electrical work associated with water well and irrigation equipment.
