Prepare for the Iowa Master Electrician Examination with a comprehensive books and courses rental package built around the current 2023 National Electrical Code and the electrical knowledge areas tested by PSI for the Iowa Electrical Examining Board.
This package includes rental access to the National Electrical Code Handbook, 2023 and Ugly's Electrical References, along with 6 months of course access. Both rental books are provided highlighted and tabbed to help organize study, improve reference navigation, and support a more structured approach to preparing for the Iowa Master Electrician exam.
The Iowa Master Electrician examination is administered by PSI for the Iowa Electrical Examining Board. The current exam is based on the 2023 National Electrical Code and tests 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 an approved reference for use during the current open-book Master Electrician examination. PSI permits the approved NEC reference to be highlighted, underlined, indexed, and prepared with permanent tabs before the test. 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.
Because this is a rental package, the books included with the package are rental books rather than books sold as permanent purchases. The $200 portion of the initial payment is identified as the refundable deposit.
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 includes 10 non-scored questions. PSI provides an additional 30 minutes for these items. Non-scored questions are used for examination development and do not affect the candidate's final score.
The current Master Electrician examination content outline is:
Wiring and Protection is the largest single area of the examination at 25%. Wiring Methods and Materials and Equipment for General Use each account for another 20%, meaning those three categories represent the majority of the scored test.
Master Electrician candidates should be prepared to work with code requirements as well as calculations and practical electrical applications. Preparation should include conductor sizing, load calculations, grounding and bonding, overcurrent protection, services, feeders, wiring methods, motors, equipment, special occupancies, and other NEC subjects included in the PSI outline.
The Iowa Master Electrician examination is an open book test. PSI currently permits candidates to bring either the NFPA 70 National Electrical Code, 2023 Edition or the National Electrical Code Handbook, 2023 into the examination center.
This rental package includes the 2023 National Electrical Code Handbook, which is one of the approved exam-room references.
PSI permits the approved NEC reference to be highlighted, underlined, and indexed before the examination. Permanent tabs are also permitted. A permanent tab is one that would tear the page if removed.
Temporary removable tabs, including Post-it-style tabs, are not permitted. Candidates may not bring loose or attached additional papers with the approved reference, and handwritten notes are not allowed in the book. Candidates may not write, highlight, underline, or index the reference once the examination session has begun.
Ugly's Electrical References is not permitted inside the examination center. It should be used as a study resource for formulas, electrical theory, calculations, conductor information, voltage drop, motors, transformers, grounding, and other practical electrical topics before exam day.
The Iowa Electrical Examining Board oversees statewide electrical licensing through the Iowa Department of Inspections, Appeals, and Licensing.
Iowa defines a Master Electrician as a person with the qualifications and technical knowledge necessary to properly plan, lay out, supervise, and install electrical wiring and equipment for light, heat, and power.
For the standard Master Electrician examination pathway, Iowa requires at least one year of experience acceptable to the Board as a licensed Class A or Class B Journeyman Electrician.
Iowa also recognizes other qualifying pathways. A State of Iowa-licensed Master Class B Electrician may qualify for the Master examination, and Iowa maintains provisions for certain electricians with documented historical master-level experience predating the current licensing system.
Applicants seeking to test must submit the appropriate Iowa electrical license application and a testing sponsorship request. Once sponsorship is approved, the candidate receives the authorization needed to register for the examination with PSI.
Iowa's statewide electrical requirements currently use the 2023 National Electrical Code. Following legislation effective June 2, 2026, Iowa returned to the unamended 2023 NEC as the statewide minimum standard except for provisions specifically established in Iowa law.
Ugly's Electrical References is not an exam-room-approved reference for the current Iowa Master Electrician examination.
General Electrical Knowledge accounts for 10% of the examination. Review electrical terminology, theory, Ohm's law, power, voltage, current, resistance, conductor properties, and electrical calculations. Ugly's Electrical References can help reinforce formulas during study.
Wiring and Protection represents 25%, the largest portion of the test. Candidates should devote substantial time to branch circuits, feeders, services, grounding and bonding, overcurrent protection, conductor sizing, load calculations, disconnects, and related NEC requirements.
Wiring Methods and Materials accounts for 20%. Review conductors, cables, raceways, boxes, enclosures, fittings, support requirements, protection from physical damage, box fill, raceway fill, wet and damp locations, and permitted wiring methods.
Equipment for General Use also represents 20%. Study motors, motor circuits, transformers, generators, luminaires, receptacles, switches, appliances, heating equipment, and other commonly encountered electrical equipment.
Special Occupancies accounts for 10%. Master candidates should understand NEC requirements for locations and occupancies where specialized wiring methods, equipment, or protection are required.
Special Equipment, Special Conditions, and Communication Systems each represent 5%. These areas should not be ignored simply because their individual percentages are smaller. Together they account for 15% of the examination.
A useful study method is to divide preparation into code navigation, calculations, and application practice. Use the highlighted and tabbed NEC Handbook to locate requirements repeatedly until major sections become familiar.
Practice calculations involving services, feeders, branch circuits, conductor ampacity, motors, transformers, loads, and voltage drop. Ugly's can be useful while learning and reviewing the formulas, but candidates should eventually practice without it because the book is not allowed during the examination.
The Master Electrician scored examination provides 240 minutes for 100 questions, giving candidates an average of approximately 2.4 minutes per scored question. Efficient NEC navigation can help preserve time for multi-step calculations and questions that require careful reading.
The included 6 months of course access gives candidates a structured period for working through exam preparation while using the highlighted and tabbed rental books alongside their course study.
Please allow up to 15 business days for book & course rental package orders.
