Exam Details

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

The examination also includes 6 non-scored questions. PSI provides an additional 15 minutes for these items. The 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 examination areas at 25% each. Equipment for General Use represents another 20%. Together, these three areas account for 70% of the published examination outline.

Master Residential Electrician candidates should be comfortable applying residential electrical requirements involving services, feeders, branch circuits, load calculations, conductor sizing, grounding and bonding, overcurrent protection, wiring methods, boxes, raceways, appliances, motors, heating and cooling equipment, and communication systems.

Open Book Test

The Iowa Master Residential 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 NFPA 70 National Electrical Code Handbook, 2023. The 2023 NEC Handbook included with The 1 Package is therefore an approved reference for the current examination.

The approved reference may be highlighted, underlined, and indexed before the examination. Permanent tabs are permitted. PSI defines permanent tabs as tabs that would tear the page if removed.

Temporary removable tabs are not allowed. Candidates may not bring additional loose or attached papers with approved references, and handwritten notes are prohibited. Candidates also may not write, highlight, underline, or index the reference during the examination session.

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

Because the examination is timed, candidates should practice using the highlighted and tabbed NEC Handbook until major residential subjects become familiar. Efficient reference navigation can preserve more time for calculations and multi-step code questions.

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. Candidates using the standard pathway need 2,000 hours of verified experience as a Residential Electrician or Journeyman Electrician.
3. Submit the applicable Iowa electrical license application. Candidates provide the documentation required by the Electrical Examining Board.
4. Request testing sponsorship. Iowa requires Board authorization before candidates may schedule the Residential Master Electrician examination through PSI.
5. Receive authorization to test. Once approved, the candidate receives the information needed to schedule with PSI.
6. Prepare for the 2023 NEC-based examination. Study all eight examination areas and practice residential calculations, electrical theory, and NEC navigation.
7. Complete the PSI examination. The scored portion contains 60 questions and provides 180 minutes.
8. Achieve a score of at least 70%. Passing the approved examination satisfies the examination component of the applicable licensing pathway.
9. Complete the remaining Residential Master licensing requirements. Submit the required documentation and finish the state licensing process.
10. Address Residential Electrical Contractor requirements before operating a contracting business. Iowa distinguishes the individual Residential Master license from the contractor credential used to operate a residential electrical contracting business.

Application Service is included with The 1 Package. The service provides assistance with organizing and working through the Iowa licensing application process associated with the package.

State Requirements

Under Iowa's standard Residential Master Electrician 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 Board-approved Residential Master Electrician examination with a score of at least 70%.

Iowa also recognizes another Residential Master examination pathway for a person who holds a current Special Electrician license with the Residential endorsement and has 4,000 hours of verified experience.

Iowa defines residential electrical work as qualifying electrical work in a residence containing no more than four living units within the same building.

The residential licensing scope can also include qualifying accessory structures located on the same lot as the dwelling unit or units. These accessory structures may be no greater than 3,000 square feet in floor area, no more than two stories in height, and must be used incidentally to the dwelling.

A Residential Master Electrician license is different from an Iowa Residential Electrical Contractor license. Iowa permits a Residential Electrical Contractor license to be issued to a person who is licensed as a Master Class A or B Electrician or as a Residential Master and who is properly registered with the state as a contractor.

All Iowa electrical contractors are required to meet the applicable contractor-registration requirements before operating under the contractor credential. This is one reason The 1 Package includes business-setup and Contractor Compliance Guidance in addition to exam preparation.

Iowa currently tests electrical candidates using the 2023 National Electrical Code. The state's current minimum electrical standard also uses the 2023 NEC subject to requirements established under Iowa law.

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

Residential Master candidates should be prepared for questions that combine several NEC concepts. A dwelling service problem can involve calculated load, service conductors, overcurrent protection, grounding, bonding, and equipment requirements in one question.

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.

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

Special Occupancies, Special Equipment, Special Conditions, and Communication Systems each account for 5%. Together they represent 20% of the examination and should remain part of a complete study plan.

The scored examination allows 180 minutes for 60 questions, giving candidates an average of approximately three minutes per scored question. Efficient reference navigation is especially useful when a question requires a calculation followed by verification against an NEC provision.
