The package price is $890 plus a refundable deposit of $200, for a total initial payment of $1,090. The books included with this package are rental books, and both books are supplied highlighted and tabbed for structured study.

Exam Details

The current Iowa Residential Electrician Examination contains 50 scored questions. Candidates receive 120 minutes to complete the scored portion and must achieve a score of at least 70% to pass.

The examination also includes 5 non-scored questions. PSI provides an additional 15 minutes for these questions. The non-scored questions are used for examination development and do not affect the candidate's final score.

The current Residential Electrician 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, accounting for 25% each. Equipment for General Use represents another 20%. Together, these three categories make up 70% of the published examination outline.

Candidates should also prepare for general electrical knowledge and the smaller specialized categories. Residential electrical work can require familiarity with branch circuits, required dwelling circuits, services, feeders, conductor sizing, GFCI and AFCI protection, grounding and bonding, wiring methods, boxes, raceways, appliances, motors, and communication systems.

Open Book Test

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

For the current examination, candidates may use the 2023 National Electrical Code or the 2023 National Electrical Code Handbook. This rental package includes the National Electrical Code Handbook, 2023.

The approved reference may be prepared before the examination in accordance with PSI's rules. The NEC reference may be highlighted, underlined, indexed, and equipped with permanent tabs. Permanent tabs should be attached in a manner consistent with the testing provider's reference requirements.

Temporary removable tabs, such as Post-it-style tabs, are not permitted. Loose or separately attached papers are also prohibited. Candidates should prepare their approved book before entering the testing center rather than attempting to mark or reorganize the book during the examination.

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

Because the examination is timed, simply having an NEC Handbook available is not enough. Candidates should practice using the highlighted and tabbed reference until common residential subjects can be located efficiently.

Licensing Steps

The Iowa Residential Electrician license is administered by the Iowa Electrical Examining Board through the Iowa Department of Inspections, Appeals, and Licensing.

1. Determine which Residential Electrician qualification pathway applies. Iowa recognizes multiple pathways based on apprenticeship, approved electrical education, supervised residential experience, or qualifying experience as an Unclassified Person.
2. Complete the required training and experience. The required hours depend on the pathway used by the applicant.
3. Submit the applicable Iowa license application. Candidates seeking licensure by examination must provide the documentation required by the Iowa Electrical Examining Board.
4. Request testing sponsorship. Iowa requires state sponsorship before a candidate may schedule the Residential Electrician examination with PSI.
5. Receive authorization to test. Once approved, the candidate can proceed with PSI examination scheduling.
6. Prepare for the 2023 NEC examination. Study all eight examination categories and practice both electrical calculations and code navigation.
7. Use the highlighted and tabbed NEC Handbook consistently. Become familiar with important dwelling-unit requirements, tables, articles, definitions, and residential wiring rules.
8. Take the PSI examination. The scored portion contains 50 questions and provides 120 minutes.
9. Earn at least 70%. Candidates using the examination pathway must meet the current passing requirement.
10. Complete the remaining licensing requirements. Licensure is issued after the required experience, examination, application, and other applicable Board requirements have been satisfied.

State Requirements

Iowa provides a specific Residential Electrician license for individuals performing electrical work in qualifying residential buildings. Residential electrical work generally applies to a residence containing no more than four living units within the same building.

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

Iowa provides several ways to qualify for the Residential Electrician examination and license.

One pathway applies to candidates with 6,000 hours of experience as a registered apprentice electrician. Under Iowa's current sponsorship requirements, an applicant using this pathway may take the examination after completing 5,000 hours of apprentice experience, although the license is not issued until the full 6,000 hours have been completed.

Another pathway applies to applicants who have completed 4,000 hours of experience working under the direct supervision of a Residential Master Electrician, Residential Electrician, Master Electrician, or Journeyman Electrician and have successfully completed at least one academic year of an approved electrical trade school.

Iowa also provides a pathway for qualifying licensed Unclassified Persons with 8,000 hours of verified experience, including at least 2,000 hours of verified residential wiring experience.

Candidates who successfully complete a registered residential electrician apprenticeship program may also qualify under the applicable Iowa requirements.

State testing sponsorship is required before scheduling with PSI. Iowa's licensing guidance directs candidates to submit the application associated with the license that requires testing before examination authorization is issued.

Iowa currently uses the 2023 National Electrical Code as its statewide minimum electrical standard. The Iowa Electrical Examining Board also confirms that PSI is currently testing electrical candidates using the 2023 NEC.

Reference Books

Exam Room Approved Books

• National Electrical Code Handbook, 2023
  The NEC Handbook included with this rental package is an approved reference for use during the current Iowa Residential Electrician examination. Candidates may use the 2023 NEC or 2023 NEC Handbook under the applicable PSI reference rules.

Ugly's Electrical References is a study resource and is not currently allowed inside the examination center.

Test Information and Study Materials

General Electrical Knowledge accounts for 10% of the examination. Review voltage, current, resistance, power, electrical terminology, conductor properties, calculations, and other electrical fundamentals.

Ugly's Electrical References can be used during study to reinforce formulas and common calculations. Candidates should gradually transition to solving calculation problems without the book because it will not be available during the actual examination.

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

Residential candidates should be particularly comfortable with NEC requirements involving kitchens, bathrooms, laundry areas, garages, outdoor locations, bedrooms, basements, and other common dwelling areas where specific protection or circuit requirements apply.

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

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 represent 5%. These smaller areas should remain part of the study plan because together they account for 20% of the published examination outline.

A productive approach is to combine code-navigation practice with electrical calculations and exam-style questions. Use the highlighted and tabbed NEC Handbook during course study so important articles become familiar before testing.

The scored portion allows 120 minutes for 50 questions, providing an average of approximately 2.4 minutes per scored question. Candidates who can recognize the likely NEC article before opening the book can spend more time analyzing the actual requirement instead of searching broadly.

When reviewing missed practice questions, identify whether the problem involved the wrong NEC article, an overlooked exception, an incorrect calculation, a misunderstood definition, or difficulty applying a general requirement to residential work.

The package's 6 months of course access provides a structured study period for combining course preparation with repeated use of the highlighted and tabbed rental books.

Please allow up to 15 business days for book & course rental package orders.
