What Is an Iowa Journeyman Electrician?

Iowa describes a Journeyman Electrician as a person with the qualifications needed to wire for or install electrical wiring and equipment.

A journeyman is different from a Master Electrician. A Master Electrician has the qualifications and technical knowledge to plan, lay out, supervise, and install electrical wiring and equipment. A Journeyman Electrician performs electrical installation work under the general direction of a Master Electrician.

Iowa's standard journeyman examination is associated with the Class A Journeyman Electrician license.

Class A Journeyman vs. Class B Journeyman

Iowa maintains both Class A and Class B Journeyman Electrician license categories, but they are not two equal paths for a new electrician choosing which exam to take.

Class B licenses can also be restricted by local ordinances. For most electricians pursuing journeyman licensure today, the Class A license is the relevant path.

The Traditional Class A Journeyman Qualification Path

One of Iowa's main Class A Journeyman qualification routes is the registered apprenticeship path.

Under this route, an applicant must:

1. Successfully complete a registered apprenticeship program.
2. Complete four years of experience as an apprentice electrician.
3. Pass the Board-approved journeyman examination.
4. Earn a score of 70 percent or higher.
5. Have passed the exam within 24 months before submitting the new license application.
6. Submit the completed Iowa application and applicable fee.

Apprenticeship combines classroom instruction with thousands of hours of real electrical work. By the time you reach the journeyman exam, you should have seen much more than pictures of panels in a textbook.

Iowa Also Provides Alternative Journeyman Paths

Registered apprenticeship is not the only way Iowa's current rules allow a person to qualify for Class A Journeyman licensure.

Other routes can apply to applicants who:

• Already hold an Iowa Class B Journeyman license
• Hold a qualifying electrician license from another state
• Have extensive Iowa electrical work experience and required continuing education
• Hold an Iowa Residential Electrician or Residential Master license and complete qualifying commercial or industrial experience
• Complete an approved postsecondary electrical education program plus qualifying work experience

These routes have different documentation requirements. Do not assume that one electrician's application checklist automatically applies to another electrician with a different background.

Iowa Journeyman Electrician Exam Format

PSI administers the current Iowa electrical examinations for the Iowa Electrical Examining Board.

You will not know which questions are non-scored, so treat every question like it counts. Trying to identify the experimental questions is an entertaining way to waste exam time and accomplish absolutely nothing.

What Is on the Iowa Journeyman Electrician Exam?

PSI divides the journeyman examination into seven major content areas.

PSI notes that the percentages may not total exactly 100 because of rounding. Wiring and Protection is the largest category at 25 percent. Wiring Methods and Materials and Equipment for General Use each account for another 19 percent.

Wiring and Protection Is the Largest Exam Area

Wiring and Protection should be one of the first sections in your study plan because it carries the most weight.

Study subjects such as:

• Branch circuits
• Feeders
• Services
• Overcurrent protection
• Grounding and bonding
• Required circuits and outlets
• Conductor protection
• Load calculations

This category connects directly with everyday electrical work. The trick is knowing the exact NEC requirement rather than relying only on field habits.

Wiring Methods and Materials Is Worth 19 Percent

Journeyman electricians need to understand which wiring methods are permitted and how they must be installed.

Review:

• Conductors and cables
• Raceways
• Boxes and fittings
• Flexible wiring methods
• Support and securing requirements
• Protection from physical damage
• Wet and damp locations
• Box fill
• Raceway fill
• Ampacity and temperature limitations

Pay attention to where a wiring method is allowed, where it is prohibited, and which exceptions change the normal rule. The NEC enjoys hiding a lot of important information immediately after the sentence you thought answered the question.

Equipment for General Use Is Another 19 Percent

Electrical systems contain far more than conductors and raceways. Journeyman electricians need broad knowledge of equipment connected to those systems.

Study equipment such as:

• Switches
• Receptacles
• Panelboards
• Transformers
• Motors
• Motor controllers
• Appliances
• Luminaires
• Air-conditioning equipment
• Electric heating equipment

Motors deserve extra calculation practice because conductor sizing, overload protection, short-circuit protection, controllers, and disconnecting means can all appear in the same family of questions.

Special Occupancies Carry 13 Percent

Special Occupancies is large enough that skipping it can create a serious hole in your score.

Depending on the installation, special occupancy topics can include:

• Hazardous locations
• Health care facilities
• Places of assembly
• Commercial garages
• Agricultural buildings
• Manufactured buildings
• Other occupancies with specialized electrical rules

Special occupancy questions reward candidates who know when the general electrical rules are no longer the whole story.

Do Not Ignore Special Equipment and Special Conditions

Special Equipment and Special Conditions each account for about six percent of the exam.

Review topics involving:

• Generators
• Photovoltaic systems
• Energy storage
• EV charging equipment
• Swimming pools and spas
• Emergency systems
• Legally required standby systems
• Optional standby systems

Six percent may sound small until your score report says you missed passing by two questions.

The Current Iowa Exam Uses the 2023 NEC

This point is especially important in 2026 because newer code editions and study products are already available.

Iowa also returned to the unamended 2023 NEC as its statewide minimum electrical installation standard in June 2026, subject to the exclusions and modifications written directly into Iowa law.

If you want a package aligned directly with the current exam code edition, review the 2023 Iowa Journeyman Electrician Study Guide, Calculations Guide, and NEC Combo.

Newer 2026 NEC study products can be useful for learning the newest code, but always follow the current PSI bulletin for the reference you bring on exam day.

Know the PSI Open-Book Rules

The journeyman exam is open book, but it is not an "everything on your bookshelf is invited" kind of open book.

PSI currently allows:

• The 2023 NEC or 2023 NEC Handbook
• Highlighting completed before the examination
• Underlining completed before the examination
• Indexing completed before the examination
• Permanent tabs
• A properly bound printed copy when using an approved downloaded reference

PSI does not allow:

• Written notes inside the reference
• Writing or marking the reference during the exam
• Loose supplemental papers
• Attached supplemental notes
• Temporary removable tabs
• Ugly's Electrical References in the testing room

Ugly's can still be useful while studying. It just does not get a ticket to test day.

Practice NEC Navigation Before You Practice Speed

Open-book exams reward candidates who know where information lives. Searching the NEC from page one on every question will make three hours feel surprisingly short.

1. Identify the topic before opening the code.
2. Think of the likely NEC article.
3. Use Article 100 definitions when terminology matters.
4. Use the index when the article is not obvious.
5. Read the complete rule.
6. Check exceptions and tables.
7. Answer the question and move forward.

Practice this process repeatedly. The goal is to turn code navigation into a skill instead of a scavenger hunt.

Electrical Calculations Need Their Own Study Time

Journeyman exams do not test only your ability to locate paragraphs. Electrical calculations can require several steps and the correct NEC table or rule.

Practice calculations involving:

• Services and feeders
• Branch circuits
• Conductor ampacity
• Voltage drop
• Box fill
• Raceway fill
• Motors
• Transformers
• Dwelling and commercial loads
• Overcurrent protection

PSI provides an online calculator, and candidates may bring a qualifying silent, battery-powered, non-programmable calculator without paper tape or an alphabetic keyboard.

Practice with a simple calculator before the exam. You want to spend your time solving electrical problems, not discovering that your favorite calculator has seventy-three features you have never used.

A Journeyman Can Supervise Apprentices, With Limits

Iowa allows a Journeyman Electrician to directly supervise apprentice electricians and unclassified persons while performing electrical work.

However, one master, journeyman, residential master, or residential electrician may not directly supervise more than three apprentices or unclassified persons at the same time.

The journeyman must still work under the general direction of a Master Electrician.

Journeyman Electrician vs. Electrical Contractor

Passing the journeyman exam does not automatically allow you to open an unrestricted Iowa electrical contracting business.

Iowa treats the Electrical Contractor license separately. An electrical contractor must hold or employ a person who holds an active Master Electrician license and must satisfy Iowa contractor-registration requirements.

That makes the usual career path look something like this:

1. Apprentice or another qualifying electrical path
2. Class A Journeyman Electrician
3. Qualifying journeyman experience
4. Class A Master Electrician
5. Electrical Contractor license when business requirements are satisfied

The Journeyman License Can Lead to Master Electrician

Iowa currently allows a Class A Master Electrician license applicant to qualify after completing one year of experience as a licensed journeyman electrician and passing the Board-approved master examination with a score of 70 percent or higher.

That makes the journeyman credential an important career milestone rather than the end of the road.

Journeyman experience gives you more time working with services, feeders, commercial systems, motors, equipment, troubleshooting, special occupancies, and code requirements before taking on master-level planning and supervisory responsibility.

Iowa Journeyman License Term and Continuing Education

Iowa currently lists the Class A Journeyman Electrician license as a three-year credential.

Full-cycle journeyman renewal currently requires 18 hours of approved continuing education. Iowa guidance calls for at least six hours of electrical-code education plus additional approved electrical installation education.

Keep your continuing-education certificates. License renewal is a much more relaxing experience when your proof of completion is somewhere more specific than "probably in an email."

Build Your Study Plan Around the PSI Blueprint

Random studying can feel productive while quietly ignoring the topics that appear most often on the exam.

1. Start with Wiring and Protection. It is the largest category at 25 percent.
2. Study Wiring Methods and Materials. This category represents another 19 percent.
3. Review Equipment for General Use. It also carries 19 percent.
4. Study Special Occupancies. At 13 percent, it deserves real preparation.
5. Practice General Electrical Knowledge. Theory, terminology, and calculations support the entire exam.
6. Rotate through Special Equipment and Special Conditions. Smaller categories still contain valuable points.
7. Finish with timed NEC practice. Train for 80 scored questions in three hours.

Review Every Practice Question You Miss

A practice test becomes useful when you study the mistakes instead of admiring the percentage for twelve seconds and moving on.

1. Identify the exam category.
2. Locate the controlling NEC section.
3. Read the complete rule and its exceptions.
4. Redo calculations from the beginning.
5. Explain why the correct answer works.
6. Explain why your original answer was incorrect.
7. Practice another question on the same topic later.

If motor questions keep causing trouble, study motors. If grounding keeps causing trouble, study grounding. If every missed question involves a calculation, your calculator is not the problem. More calculation practice is.

Prepare for the License and the Electrical Career

The Iowa Journeyman Electrician license represents a major move from supervised apprentice training into licensed electrical work with greater responsibility.

Strong preparation should combine real field experience with NEC knowledge. Review services, feeders, branch circuits, grounding, bonding, conductors, raceways, boxes, motors, transformers, equipment, hazardous locations, generators, standby systems, and electrical calculations.

Most importantly, become fast with the 2023 NEC. The exam allows the code book, but the clock does not wait while you slowly rediscover how the index works.
