The Iowa Master Residential Electrician examination is administered through PSI for the Iowa Electrical Examining Board. The current examination is based on the 2023 National Electrical Code and covers general electrical knowledge, wiring and protection, wiring methods and materials, equipment for general use, special occupancies, special equipment, special conditions, and communication systems.
The 2023 National Electrical Code Handbook is approved for use during the current open-book examination. PSI allows the approved NEC reference to be highlighted, underlined, indexed, and prepared with permanent tabs before the examination. Ugly's Electrical References is included as a study resource but is not permitted inside the examination center.
Please allow up to 15 business days for book & course rental package orders.
The package price is $890 plus a refundable deposit of $200, for a total initial payment of $1,090. Both books included with the package are rental books and are supplied highlighted and tabbed for organized study.
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:
Wiring and Protection and Wiring Methods and Materials are the two largest areas of the examination at 25% each. Equipment for General Use represents another 20%. Together, these three content areas make up 70% of the published examination outline.
Master Residential Electrician candidates should be prepared to apply residential electrical requirements rather than simply recognize code language. Preparation should include dwelling-unit branch circuits, services, feeders, load calculations, conductor sizing, GFCI and AFCI protection, grounding and bonding, overcurrent protection, wiring methods, boxes, raceways, cables, appliances, motors, and other equipment commonly encountered in residential installations.
The Iowa Master Residential Electrician examination is an open book test using approved reference material.
PSI currently allows 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 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, such as Post-it-style tabs, are not allowed. Additional loose or attached papers may not be brought into the testing center with the approved reference. PSI also prohibits handwritten notes in the book before or during the examination.
Ugly's Electrical References is not allowed inside the current examination center. It is included as a study resource for formulas, electrical calculations, conductor information, voltage drop, motors, transformers, grounding, and practical field information.
The highlighted and tabbed NEC Handbook should be used repeatedly during the course-access period. Because the exam is timed, candidates benefit from becoming familiar with the location of common residential requirements before test day instead of relying on broad searches during the examination.
Iowa electrical licensing is administered by the Iowa Electrical Examining Board through the Iowa Department of Inspections, Appeals, and Licensing.
Iowa defines a Residential Master Electrician as a person with the necessary qualifications, training, experience, and technical knowledge to properly plan, lay out, and supervise the performance of residential electrical installations.
Current Iowa rules provide a Residential Master Electrician pathway for an applicant who holds a current license issued by the Board as a Residential Electrician or Journeyman Electrician, completes the required qualifying experience, and passes a Board-approved Residential Master Electrician examination with the required score.
The current experience requirement is 2,000 hours of verified experience as a Residential Electrician or Journeyman Electrician.
Iowa residential electrical licensing applies to work in a residence containing no more than four living units within the same building. Residential licensing may also cover qualifying accessory structures located on the same lot as the dwelling units.
Qualifying accessory structures may be no greater than 3,000 square feet in floor area, no more than two stories in height, and used incidentally to the residential property.
Applicants using the examination pathway must obtain testing sponsorship from the Iowa Electrical Examining Board. The candidate completes the applicable application and sponsorship process before scheduling with PSI.
Iowa currently uses the 2023 National Electrical Code as the statewide minimum electrical standard. Iowa's current electrical licensing guidance also confirms that PSI is testing electrical candidates on the 2023 NEC.
Ugly's Electrical References is not an exam-room-approved reference for the current Iowa Master Residential Electrician examination.
General Electrical Knowledge accounts for 10% of the examination. Candidates should review electrical theory, terminology, voltage, current, resistance, power, conductor properties, and common electrical calculations.
Ugly's Electrical References can help reinforce formulas during preparation. Use it to review Ohm's law, voltage drop, electrical power, conductor information, conversions, and other practical relationships, then transition to solving similar questions without the book because it cannot be used during the actual exam.
Wiring and Protection represents 25% of the examination. Review services, feeders, dwelling-unit branch circuits, load calculations, conductor sizing, grounding and bonding, overcurrent protection, GFCI protection, AFCI protection, disconnects, and other protective requirements.
Residential master candidates should be prepared for questions that combine several NEC concepts. A single dwelling-service problem may involve calculated load, service conductor sizing, grounding, bonding, overcurrent protection, and equipment requirements.
Wiring Methods and Materials also accounts for 25%. Study cables, raceways, conductors, boxes, fittings, enclosures, support requirements, physical protection, box fill, raceway fill, wet and damp locations, underground installations, and permitted residential wiring methods.
Candidates should practice identifying when general wiring rules apply and when a specific equipment or occupancy article adds additional requirements.
Equipment for General Use represents 20%. Review receptacles, switches, luminaires, appliances, motors, transformers, heating equipment, air-conditioning equipment, controllers, disconnecting means, and other electrical equipment commonly installed in residential buildings.
Equipment questions may require candidates to use nameplate information, determine conductor or overcurrent requirements, identify disconnect rules, or apply grounding and bonding provisions.
Special Occupancies accounts for 5%. Study locations and occupancies where additional NEC provisions apply beyond ordinary residential wiring rules.
Special Equipment represents 5%. Review specialized electrical equipment and the dedicated NEC articles governing its installation and protection.
Special Conditions accounts for 5%. Candidates should study systems such as emergency and standby systems, interconnected sources, energy-storage systems, and other installations governed by special NEC conditions.
Communication Systems represents the final 5%. Review communications wiring and related low-voltage requirements, especially where these systems interact with residential electrical installations.
A productive study routine should combine reference navigation, calculations, and application questions. Use the highlighted and tabbed NEC Handbook throughout the 6 months of course access so the placement of important articles and tabs becomes familiar.
The scored examination allows 180 minutes for 60 questions, providing an average of approximately three minutes per scored question. Efficient code navigation can preserve time for calculations and questions that require several steps.
When reviewing a missed practice question, identify whether the problem resulted from an incorrect calculation, choosing the wrong NEC article, overlooking an exception, misreading a table, or applying a general rule when a more specific residential provision controlled.
Please allow up to 15 business days for book & course rental package orders.
