Exam Details

The current Iowa Irrigation System Wiring examination contains 50 scored questions. Candidates receive 120 minutes for the scored portion and must achieve at least 70% correct to pass.

The examination also includes 5 non-scored questions. PSI provides an additional 15 minutes for these questions. The non-scored items are used for examination development and do not affect the candidate's final score.

The current examination content outline is:

• General Knowledge – 12%
• Wiring and Protection – 20%
• Wiring Methods and Materials – 20%
• Equipment for General Use – 20%
• Special Equipment – 14%
• Low Voltage – 14%

Wiring and Protection, Wiring Methods and Materials, and Equipment for General Use each account for 20% of the examination. Together, these three areas represent 60% of the published exam outline.

Candidates should be prepared for questions involving electrical fundamentals, conductor selection, branch circuits, grounding and bonding, overcurrent protection, wiring methods, boxes and enclosures, electrical equipment, motors and controls, irrigation-related electrical components, and low-voltage circuits.

Open Book Test

The Iowa Irrigation System Wiring examination is an open book test using approved reference material.

PSI currently allows candidates to use either the NFPA 70 National Electrical Code, 2023 Edition or the NFPA 70 National Electrical Code Handbook, 2023 in the examination center. The highlighted and tabbed National Electrical Code Handbook included with The 1 Package is therefore an approved exam-room reference.

The open-book format makes efficient NEC navigation an important part of preparation. Candidates should know how to locate requirements involving wiring methods, conductor ampacity, grounding, overcurrent protection, motors, equipment, and low-voltage systems without spending excessive time searching.

Ugly's Electrical References is not permitted in the current PSI examination center. It is included as a preparation resource for formulas, electrical theory, conductor information, voltage drop, grounding, motors, transformers, conversions, and calculations.

Simplified Irrigation Design, 2nd Ed, 1995 is also included as a study resource. It is not listed by PSI as an approved examination-room reference for the Iowa Irrigation System Wiring examination.

Licensing Steps

The Iowa Electrical Examining Board administers the state electrical licensing process. Irrigation System Wiring is available as Endorsement 1 on an Iowa Special Electrician license.

1. Select the Irrigation System Wiring endorsement. This is the applicable Special Electrician endorsement for qualifying irrigation-system electrical work.
2. Choose the applicable qualification pathway. Iowa permits candidates to qualify by passing a supervised examination approved by the Board or by completing the required documented irrigation-system wiring experience.
3. Submit the appropriate Iowa electrical license application. Applicants using the examination pathway must submit an application for a license requiring testing.
4. Request state testing sponsorship. The Iowa Electrical Examining Board must approve sponsorship before the candidate schedules the PSI examination.
5. Receive authorization to test. Once sponsorship is approved, the candidate can proceed with PSI scheduling.
6. Prepare using the 2023 NEC. Current PSI testing uses the 2023 National Electrical Code.
7. Study all six examination content areas. Give particular attention to wiring and protection, wiring methods, equipment, and low-voltage electrical systems.
8. Take the PSI examination. The scored portion contains 50 questions and provides 120 minutes.
9. Earn at least 70%. A passing score satisfies the examination pathway for the Irrigation System Wiring endorsement.
10. Complete the remaining licensing requirements. Submit any required final information and complete the Special Electrician licensing process.
11. Address business and contractor requirements separately. Candidates planning to operate a contracting business should also complete the applicable business-registration and contractor-compliance steps.

Application Service is included with The 1 Package to provide support with organizing and working through the applicable Iowa licensing application process.

State Requirements

Iowa administrative rules identify Irrigation System Wiring as Endorsement 1 under the Special Electrician license. The endorsement may be issued when requested by an applicant who has either passed a supervised examination approved by the Board or completed two years, or 4,000 hours, of documented experience in the wiring of irrigation systems.

Candidates pursuing the examination pathway do not need prior electrical licensure or experience solely to receive Iowa testing sponsorship for the Irrigation System Wiring endorsement. They must still complete the required application and obtain sponsorship before scheduling the examination.

Iowa's licensing process allows applicants to apply through the state's electrical licensing system. Applicants who are required to test may submit a new license application by examination. Once the application is reviewed and testing sponsorship is granted, the candidate can proceed with PSI scheduling.

The Irrigation System Wiring endorsement is a Special Electrician credential. It should not be treated as the equivalent of a Class A Master Electrician, Journeyman Electrician, or general Electrical Contractor license.

Iowa defines a general Electrical Contractor license separately. A person holding or applying for a Special Electrician Irrigation System Wiring endorsement should therefore consider the exact business structure, work scope, contractor registration, and licensing requirements that apply to the business being established.

State contractor registration is also a separate process. Iowa requires contractor registration information such as the applicable business activity classification, unemployment insurance information, workers' compensation information when applicable, and other required registration documentation.

Iowa currently applies the 2023 National Electrical Code as the statewide electrical standard, subject to provisions established in Iowa law. Current PSI electrical examinations also use the 2023 NEC.

• National Electrical Code Handbook, 2023
  The highlighted and tabbed NEC Handbook included with The 1 Package is an approved reference for the current Iowa Irrigation System Wiring examination. PSI permits either the 2023 NEC or the 2023 NEC Handbook.

Ugly's Electrical References and Simplified Irrigation Design, 2nd Ed, 1995 are included as study resources and are not listed by PSI as approved examination-room references for this exam.

Test Information and Study Materials

General Knowledge accounts for 12% of the exam. Candidates should review basic electrical terminology, voltage, current, resistance, power, Ohm's law, electrical calculations, circuit fundamentals, and safe work concepts.

Ugly's Electrical References can be useful during this stage of preparation because it consolidates many frequently used formulas and electrical reference tables. Since Ugly's is not permitted in the examination center, candidates should use it to reinforce concepts rather than become dependent on it during practice.

Wiring and Protection represents 20%. Review branch circuits, feeders where applicable, overcurrent protection, disconnecting means, grounding, bonding, equipment protection, and conductor requirements.

Wiring Methods and Materials also accounts for 20%. Study cables, raceways, boxes, fittings, enclosures, conductor protection, support requirements, burial and underground wiring concepts, wet-location requirements, and wiring methods that may be encountered in irrigation-system installations.

Outdoor irrigation equipment commonly operates in environments where moisture, soil contact, physical damage, and underground routing are important considerations. Candidates should understand how environmental conditions affect wiring methods and equipment selection.

Equipment for General Use accounts for another 20%. Review switches, disconnects, controllers, transformers, motors, utilization equipment, and other electrical components that may be associated with irrigation systems.

Special Equipment accounts for 14%. This area rewards familiarity with NEC provisions that apply to equipment outside ordinary general-use installations. Candidates should practice identifying when specialized Code requirements apply.

Low Voltage also accounts for 14%. Irrigation systems commonly involve controllers, transformers, solenoids, sensors, and other low-voltage components. Study circuit fundamentals, wiring practices, conductor selection, voltage drop, control wiring, and the distinction between line-voltage and low-voltage portions of a system.

Voltage drop can be especially important in irrigation control circuits because wire runs may extend substantial distances between controllers and field equipment. Practice calculating and recognizing how conductor length, conductor size, current, and voltage affect circuit performance.

A strong study method is to combine NEC navigation with practical irrigation scenarios. For example, review a hypothetical controller installation and identify the supply circuit, grounding method, transformer, low-voltage conductors, valves or solenoids, wiring method, enclosure requirements, and applicable protection.

The scored portion allows 120 minutes for 50 questions, which provides an average of approximately 2.4 minutes per scored question. Candidates should practice locating important Code provisions efficiently so that more time remains for calculations and questions requiring multiple steps.

The highlighted and tabbed NEC Handbook should be used repeatedly during preparation. Familiarity with the organization of the Code can make it easier to move among general wiring requirements, wiring methods, equipment provisions, and specialized rules.

This package includes 1 year of course access, giving candidates an extended period to review exam topics, practice calculations, develop reference-navigation skills, and revisit areas that require additional study.

Please allow up to 15 business days for The 1 Package book orders.
