Exam Details

The current Iowa Master Residential Electrician Examination contains 60 scored questions. Candidates receive 180 minutes to complete the scored portion and must achieve at least 70% correct to pass.

The examination also contains 6 non-scored questions. PSI provides an additional 15 minutes for these questions. Non-scored questions are used for examination development and do not affect the candidate's final score.

The current examination content outline is:

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

Wiring and Protection and Wiring Methods and Materials are the two largest sections of the exam at 25% each. Equipment for General Use accounts for another 20%. Together, these three categories represent 70% of the published examination outline.

Master Residential Electrician candidates should be prepared to apply residential electrical requirements to practical situations involving branch circuits, feeders, services, load calculations, grounding and bonding, conductor sizing, overcurrent protection, GFCI and AFCI requirements, wiring methods, boxes, raceways, appliances, motors, and other residential electrical equipment.

Open Book Test

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

PSI currently permits candidates to bring either the NFPA 70 National Electrical Code, 2023 Edition or the NFPA 70 National Electrical Code Handbook, 2023 into the examination center. 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. PSI defines permanent tabs as tabs that would tear the page if removed.

Temporary removable tabs, including Post-it-style tabs or similar removable markers, are not permitted. Loose or attached additional papers are also prohibited. References may not contain handwritten notes, and candidates may not write, highlight, underline, or index their books during the examination session.

Ugly's Electrical References is not permitted inside the current examination center. It is included as a study resource for electrical formulas, conductor data, voltage drop, motors, transformers, grounding, and practical calculations.

The highlighted and tabbed NEC Handbook should be used repeatedly during preparation. Open-book testing still requires efficient code navigation, and candidates who know which article or table likely applies can spend more time solving the question instead of searching through the code.

Licensing Steps

Iowa electrical licensing is administered by the Iowa Electrical Examining Board within the Department of Inspections, Appeals, and Licensing.

1. Hold an eligible Iowa electrical license. The standard Residential Master pathway requires a current Residential Electrician or Journeyman Electrician license.
2. Complete the required qualifying experience. The standard pathway requires verified work experience as a Residential Electrician or Journeyman Electrician.
3. Submit the appropriate Iowa electrical license application. Candidates must provide the documentation required by the Iowa Electrical Examining Board.
4. Request testing sponsorship. Iowa requires Board approval before a candidate may schedule the Residential Master Electrician examination with PSI.
5. Receive authorization to test. Once sponsorship is approved, the candidate may proceed with PSI scheduling.
6. Prepare for the 2023 NEC-based examination. Study all eight published content areas and practice residential electrical calculations, code navigation, and application questions.
7. Use the highlighted and tabbed NEC Handbook consistently. Become familiar with residential articles, tables, definitions, exceptions, and equipment rules.
8. Take the PSI examination. The scored portion contains 60 questions and provides 180 minutes.
9. Earn at least 70%. Candidates must meet the current passing requirement.
10. Complete the licensing process. The Residential Master Electrician license is issued after all applicable experience, examination, application, and documentation requirements are satisfied.

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

State Requirements

Iowa provides a specific Residential Master Electrician license for individuals qualified to plan, lay out, supervise, and perform residential electrical installations within the scope permitted by state law.

Under the standard Iowa pathway, an applicant must hold a current Residential Electrician or Journeyman Electrician license, complete 2,000 hours of verified experience as a Residential Electrician or Journeyman Electrician, and pass the approved Residential Master Electrician examination with a score of at least 70%.

The passing examination result must fall within the timeframe required by Iowa's licensing rules for submission of the new application.

Iowa also recognizes a pathway for certain holders of a current Special Electrician license with a residential endorsement. Under that pathway, the applicant must complete the experience and examination requirements applicable to that credential.

Residential electrical licensing in Iowa generally applies to electrical work in a residence containing no more than four living units within the same building.

The residential scope also includes qualifying accessory structures located on the same lot as the dwelling unit or units. Iowa describes these as accessory structures no greater than 3,000 square feet in floor area, no more than two stories in height, and used incidentally to the dwelling.

Candidates pursuing the examination must obtain testing sponsorship from the Iowa Electrical Examining Board. After the Board approves the application and sponsorship request, the candidate receives authorization to schedule through PSI.

Iowa currently uses the 2023 National Electrical Code as the statewide minimum electrical standard. PSI also currently tests Iowa electrical candidates using the 2023 NEC.

Test Information and Study Materials

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

Ugly's Electrical References can help reinforce formulas during preparation. Use it to review calculations and electrical relationships, then practice working similar problems without it because the book cannot be used inside the examination center.

Wiring and Protection represents 25%. Review dwelling branch circuits, services, feeders, overcurrent protection, load calculations, grounding and bonding, conductor ampacity, disconnecting means, GFCI protection, AFCI protection, and service equipment.

Master Residential candidates should be comfortable combining multiple code requirements. A service calculation question can involve load calculation, service conductor sizing, grounding, bonding, overcurrent protection, and equipment requirements in the same problem.

Wiring Methods and Materials also represents 25%. Study nonmetallic-sheathed cable, conductors, raceways, boxes, fittings, enclosures, support requirements, physical protection, box fill, raceway fill, wet and damp locations, and underground wiring.

Practice locating the appropriate NEC tables and reading the notes that accompany them. Many examination questions require more than finding a single rule. Candidates may need to identify a general requirement, apply a table, and then consider an exception or specialized provision.

Equipment for General Use accounts for 20%. Review receptacles, switches, luminaires, appliances, motors, transformers, heating equipment, air-conditioning equipment, controllers, and disconnecting means.

Residential equipment questions may require the candidate to interpret nameplate information, determine conductor or overcurrent requirements, identify required disconnects, or apply grounding and bonding provisions.

Special Occupancies accounts for 5%. Review locations and occupancies that require additional NEC provisions beyond ordinary residential wiring requirements.

Special Equipment also accounts for 5%. Candidates should be familiar with specialized electrical equipment and recognize when a dedicated NEC article changes or supplements general wiring rules.

Special Conditions represents another 5%. Study systems such as emergency and standby power, interconnected power sources, energy-storage systems, and other special electrical conditions relevant to the NEC.

Communication Systems accounts for the final 5%. Candidates should review communications and low-voltage wiring requirements, particularly where those systems interact with residential electrical installations.

A strong preparation routine combines code navigation, calculations, and timed exam-style questions. Use the highlighted and tabbed NEC Handbook throughout the preparation period so frequently used residential sections become familiar.

The scored examination provides 180 minutes for 60 questions, which gives candidates an average of approximately three minutes per scored question. Efficient navigation can preserve valuable time for calculations and questions requiring several code steps.

When reviewing missed practice questions, identify the reason for the error. It may involve selecting the wrong article, overlooking an exception, misunderstanding a definition, misreading a table, or making a calculation mistake. Targeted review can make each study session more useful.

This Ultimate package includes 1 year of course access, giving candidates an extended period to work through the examination outline, revisit difficult subjects, strengthen calculation skills, and develop faster NEC-navigation habits.

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