Exam Details

The current Iowa Master Electrician Examination contains 100 scored questions. Candidates receive 240 minutes to complete the scored portion and must achieve a score of at least 70% to pass.

The examination also contains 10 non-scored questions. PSI provides an additional 30 minutes for these questions. Non-scored items are used for examination development and do not affect the candidate's final score.

The current Iowa Master Electrician examination content outline is:

• General Electrical Knowledge – 10%
• Wiring and Protection – 25%
• Wiring Methods and Materials – 20%
• Equipment for General Use – 20%
• Special Occupancies – 10%
• Special Equipment – 5%
• Special Conditions – 5%
• Communication Systems – 5%

Wiring and Protection is the largest examination category at 25%. Wiring Methods and Materials and Equipment for General Use each represent 20%. Together, those three categories account for 65% of the published Master Electrician examination outline.

Candidates should be prepared for both code-navigation and application questions. Master-level preparation should include services, feeders, branch circuits, load calculations, conductor sizing, grounding and bonding, overcurrent protection, wiring methods, motors, transformers, equipment, special occupancies, and specialized electrical systems.

Open Book Test

The Iowa Master Electrician examination is an open book test using approved reference material.

PSI currently permits candidates to use either the NFPA 70 National Electrical Code, 2023 Edition or the National Electrical Code Handbook, 2023. This Ultimate Exam Prep Rental Package includes the 2023 NEC Handbook.

The approved NEC reference may be highlighted, underlined, and indexed before the examination. Permanent tabs are also permitted. Candidates should use the highlighted and tabbed Handbook consistently during preparation so the organization of important code sections becomes familiar before test day.

Temporary removable tabs are not permitted. Candidates may not bring loose or separately attached papers with the approved reference, and handwritten notes are not allowed in the exam-room reference.

Ugly's Electrical References is not permitted inside the current examination center. It is included as a study resource rather than an exam-room reference.

An open-book electrical examination still requires efficient preparation. Candidates who know how to recognize the subject of a question and move directly to the likely NEC article can spend more time analyzing the requirement and less time searching through the book.

Licensing Steps

The Iowa Electrical Examining Board, within the Department of Inspections, Appeals, and Licensing, administers the statewide electrical licensing program.

1. Meet the Master Electrician qualification requirements. Candidates must satisfy an Iowa pathway that makes them eligible for Master Electrician examination sponsorship.
2. Complete the applicable electrical licensing application. Iowa requires candidates seeking examination sponsorship to submit an application for the license that requires testing.
3. Submit the testing sponsorship request. The Iowa Electrical Examining Board must authorize the candidate before the PSI Master Electrician examination can be scheduled.
4. Receive sponsorship approval. Approved candidates receive the information needed to register with PSI.
5. Prepare for the 2023 NEC-based examination. Study all eight published exam categories and practice both reference navigation and electrical calculations.
6. Use the highlighted and tabbed NEC Handbook during preparation. Become familiar with important articles, tables, definitions, exceptions, and common Master Electrician topics.
7. Schedule and complete the PSI examination. The current scored portion contains 100 questions and provides 240 minutes.
8. Achieve at least 70%. Candidates must meet the current passing score requirement.
9. Complete the licensing process. Once all required documentation, examination, experience, and application requirements are satisfied, the candidate completes the remaining Iowa licensing steps.

Application Service is included with this Ultimate package. The service provides assistance with organizing and working through the Iowa application process associated with the package.

State Requirements

Iowa defines a Master Electrician as a person with the qualifications and technical knowledge required to properly plan, lay out, supervise, and install electrical wiring and equipment for light, heat, and power.

The Iowa Electrical Examining Board requires candidates to qualify under an applicable Master Electrician licensing pathway before receiving examination sponsorship. State sponsorship includes submission of the appropriate application for the license requiring testing.

The standard Master Electrician pathway includes qualifying experience as a licensed Iowa journeyman electrician. Candidates should ensure that the experience and license history submitted to the Board satisfy the pathway under which they are applying.

Once the Board approves sponsorship, the candidate receives authorization needed to register for the Master Electrician examination through PSI. After successfully completing the examination, all remaining licensing documentation must be completed before the license is issued.

Iowa currently uses the 2023 National Electrical Code. As of January 1, 2024, PSI has been testing Iowa electrical candidates on the 2023 NEC.

Iowa electrical installation requirements were also affected by legislation effective June 2, 2026. Iowa now uses the unamended 2023 NEC as the statewide minimum electrical standard, except for exclusions and amendments specifically established in Iowa law.

Reference Books

• National Electrical Code Handbook, 2023
  Included Book: A highlighted and tabbed rental copy of the primary electrical code reference approved for the current Iowa Master Electrician examination.

• Ugly's Electrical References
  Included Book: A highlighted and tabbed rental study reference covering electrical formulas, Ohm's law, conductor information, voltage drop, grounding, motors, transformers, conversions, calculations, and other practical field information. It is included for study but is not approved for use inside the current PSI examination center.

Exam Room Approved Books

• National Electrical Code Handbook, 2023
  The highlighted and tabbed NEC Handbook included in this rental package is an approved reference for the current Iowa Master Electrician examination. PSI permits the 2023 NEC or 2023 NEC Handbook under its examination reference rules.

Ugly's Electrical References is included for preparation but is not an exam-room-approved reference for the current Iowa Master Electrician examination.

Test Information and Study Materials

General Electrical Knowledge accounts for 10% of the examination. Candidates should review electrical terminology, theory, Ohm's law, voltage, current, resistance, power, conductor properties, diagrams, calculations, and practical electrical concepts.

Ugly's Electrical References can help reinforce many of these fundamentals. Use it to practice equations, conductor information, voltage drop, motor calculations, and other electrical relationships before transitioning to exam-style practice using only the approved reference.

Wiring and Protection represents 25%, making it the largest examination category. Review branch circuits, feeders, services, load calculations, overcurrent protection, conductor ampacity, grounding and bonding, disconnecting means, and protective devices.

Grounding and bonding should receive focused study. Master candidates should be comfortable with grounding electrode systems, grounding electrode conductors, equipment grounding conductors, bonding jumpers, service bonding, separately derived systems, and conductor-sizing requirements.

Wiring Methods and Materials accounts for 20%. Study raceways, cables, conductors, boxes, fittings, enclosures, support requirements, physical protection, conductor fill, box fill, wet and damp locations, underground installations, and other approved wiring methods.

Many code questions require candidates to combine several provisions. For example, a conductor question may require identifying the correct ampacity table, evaluating temperature limitations, applying an adjustment or correction factor, and checking an equipment-specific requirement.

Equipment for General Use represents another 20%. Review motors, transformers, generators, appliances, luminaires, switches, receptacles, controllers, heating equipment, air-conditioning equipment, and related disconnecting and protection requirements.

Motor questions deserve careful preparation because conductor sizing, overload protection, branch-circuit short-circuit and ground-fault protection, controllers, and disconnects perform different functions and may use different sizing rules.

Special Occupancies accounts for 10%. Candidates should study locations where additional or modified electrical requirements apply because of the occupancy or operating environment.

Special Equipment, Special Conditions, and Communication Systems each account for 5%. Together, these categories represent 15% of the exam and should remain part of the study plan.

A productive preparation strategy combines code navigation, calculations, and timed practice. Use the highlighted and tabbed NEC Handbook repeatedly so commonly tested articles and tables become easier to locate.

The scored portion provides 240 minutes for 100 questions, an average of approximately 2.4 minutes per scored question. Efficient code navigation can preserve time for calculations and more complex application questions.

When reviewing a missed question, determine whether the problem came from an incorrect calculation, using the wrong NEC article, overlooking an exception, misreading a table, or failing to recognize an equipment-specific requirement. This approach helps turn practice questions into targeted study.

The Ultimate package includes 1 year of course access, giving candidates an extended period to work through the Master Electrician exam outline, electrical calculations, NEC navigation, and practice-oriented review.

Please allow up to 15 business days for ultimate book package orders.
