2023 Ohio Master Electrician + Electrician Calculations Study Guides + Flash Cards & National Electrical Code + Tabs Super Combo (Based on the 2023 NEC)

2023 Ohio Master Electrician + Electrician Calculations Study Guides + Flash Cards & National Electrical Code + Tabs Super Combo (Based on the 2023 NEC)

If you’re preparing for Ohio’s master-level electrical testing, your study time has to build real performance: fast code navigation, accurate interpretation, and calculations you can trust when the clock is running. This Super Combo is a complete, trade-focused study system built around the 2023 National Electrical Code (NEC)—the edition used for the Ohio Electrical Contractor trade exam reference list.

Ohio’s statewide electrical contractor licensing is handled through the Ohio Construction Industry Licensing Board (OCILB), part of the Ohio Department of Commerce. OCILB issues state licenses to electrical (and other trade) contractors who perform commercial work, and candidates test through PSI after OCILB determines eligibility. This bundle is designed to support that path by building the two skills that matter most in code-based testing:

• NEC navigation & application — find the right section quickly and apply it correctly to the question.
• Calculation accuracy — set up electrical math cleanly, control units, and reduce the small mistakes that cost points.

Instead of piecing together random materials, you get an organized system that supports both deep study sessions and quick daily review—so your prep stays consistent and productive.

Exam Details

Ohio’s statewide contractor trade exams are administered by PSI, and eligibility is determined by the Ohio Construction Industry Licensing Board (OCILB). The PSI Candidate Information Bulletin explains that all contractor commercial license applicants must pass the Ohio Contractor’s Business and Law exam in addition to any required trade exam, and that PSI delivers the exams through computer testing centers. The bulletin lists an examination fee of $69 per registration.

Ohio Contractor’s Business and Law Examination (required for commercial contractor licenses):

• Questions: 50 scored questions
• Pretest: 5 pretest items (not scored)
• Passing score: 70%
• Time allowed: 2 hours

Ohio Electrical Contractor Examination (trade exam):

• Questions: 100 scored questions
• Pretest: 10 pretest items (not scored)
• Passing score: 70%
• Time allowed: 4 hours

PSI also publishes a content outline for the Electrical Contractor exam, including topic areas and item counts. The outline emphasizes code-driven, job-relevant knowledge across:

• General Electrical Knowledge (10)
• Transformers and Equipment (12)
• Service Feeders and Branch Circuits (16)
• Raceways, Boxes, and Panelboards (10)
• Conductors and Cables (12)
• Control Devices (8)
• Motors and Generators (12)
• Utilization Equipment (8)
• Special Occupancies and Equipment (12)

This Super Combo is built to match that reality: Study Guide practice for code interpretation, calculations training for accuracy and speed, flash cards for consistent reinforcement, and a tabbed 2023 NEC to train navigation the right way.

Open Book Test

Ohio’s PSI Candidate Information Bulletin lists both the Business and Law exam and the Electrical Contractor exam as OPEN BOOK.

Business and Law exam (open book): PSI states that the Business and Law reference is provided in the testing center and that no highlighting or notes may be made in the book during the exam. PSI also notes candidates may bring their own reference to the exam center, but references may not be written in, and no additional papers may be brought in with approved references.

Electrical Contractor exam (open book): PSI states the Electrical Contractor exam is open book and lists the approved reference materials. The reference list includes NFPA 70 – National Electrical Code, 2023 (and/or the NEC Handbook, 2023) and other permitted references. Candidates are responsible for bringing their own references. PSI allows references to be highlighted, underlined, and/or indexed prior to the exam session, but references may not be written in, and candidates may not bring in extra papers attached to references.

Open book doesn’t mean you can “look everything up.” It means your ability to work the code efficiently becomes part of the test. The included tabbed 2023 NEC supports the exact workflow open-book exams reward:

• Identify the topic (services/feeders, raceways, motors, special occupancies, etc.).
• Navigate quickly using tabs and familiarity with the NEC’s layout.
• Confirm the exact language so you’re not guessing.
• Apply the requirement and move on without over-reading.

Licensing Steps

Ohio’s statewide contractor licensing for electrical work is handled through OCILB. The OCILB licensing process includes an application review to determine eligibility to sit for the exam, followed by PSI exam scheduling once you’re approved. The official OCILB “License Qualification Process” document explains key steps and documents required.

1. Confirm you’re pursuing the right credential.
   OCILB issues state licenses to electrical contractors who perform commercial work.
2. Meet the experience and eligibility standards before applying.
   OCILB requires applicants to be at least 18 and to have been a tradesperson in the trade for at least five years immediately prior to applying.
3. Submit your OCILB examination application and fee.
   The OCILB examination application lists an application fee of $25.
4. Complete required background checks after approval.
   The OCILB process states that, once approved (valid for one year), you must obtain a BCI and FBI background check prior to sitting for the exam.
5. Schedule your PSI exams and pass required portions.
   PSI administers the exams, and commercial contractor applicants must pass the Business and Law exam plus the trade exam.
6. Finish licensing issuance requirements after passing.
   The OCILB process document states that those who pass both sections can obtain a state license by submitting exam results, a $25 fee, and proof of contractor liability insurance.

This Super Combo supports the part you control most: preparation quality and consistency—so your exam-day workflow feels practiced instead of rushed.

State Requirements

Ohio’s OCILB publishes eligibility requirements for electrical contractor licensure. The official License Qualification Process document states that applicants must:

• Be at least 18 years of age
• Be a U.S. citizen or legal alien (with proof)
• Have been a tradesperson in the trade for not less than five years immediately prior to application

The same document outlines supporting documentation expectations, including providing the last five consecutive years of tax documents and additional qualifying documentation options (such as permits, an active journeyman card, an apprenticeship completion certificate, or approved continuing education documentation). It also describes that approved candidates must complete BCI and FBI background checks prior to sitting for the exam.

After passing, the OCILB process document states that license issuance requires submitting proof of at least $500,000 contractor liability insurance (certificate of liability insurance) and assigning the license to a contracting company as defined in Ohio law.

From a prep standpoint, the takeaway is straightforward: Ohio expects licensed contractors to demonstrate code competency and professional-level decision-making. This Super Combo is built to help you train those skills with structure—especially open-book navigation and calculation accuracy.

Reference Books

• Included Book: NFPA 70 – National Electrical Code (NEC) 2023 Paperback with Tabs
  PSI’s reference list for the Ohio Electrical Contractor exam includes NFPA 70 (NEC) 2023 (and/or the NEC Handbook 2023). This tabbed NEC helps you practice faster navigation and build an efficient open-book workflow.

PSI’s Electrical Contractor reference list also includes additional permitted references (such as Ugly’s Electrical References, 2023), but this Super Combo focuses on the core foundation you’ll use constantly in code-based practice: the 2023 NEC.

Test Information and Study Materials

Most candidates don’t struggle because they “didn’t study enough.” They struggle because their study time isn’t training the way the exam works. Ohio’s electrical contractor exam is timed and open book, which means two things matter every session: how quickly you can find the right NEC location and how confidently you can apply what you find.

1) Train “question recognition” before you open the code book.
When you practice, take a moment to name the category: services/feeders, raceways and boxes, conductors, motors, utilization equipment, special occupancies, or control devices. That small habit reduces wrong turns and saves time over the length of the exam.

2) Practice NEC navigation until it becomes automatic.
Tabs help you get into the right neighborhood of the code faster, but repetition is what makes it reliable. Use the included tabbed NEC during every practice session:

• Verify answers in the NEC even when you get the question right.
• Time your lookups and aim for steady improvement.
• Build “home base” familiarity with frequent topics like services, feeders, branch circuits, raceways, motors, and special occupancies.

3) Strengthen calculations with a repeatable workflow.
Even experienced electricians miss calculation questions due to rushed set-ups, unit mistakes, or skipped steps. The Electrician Calculations Study Guide is designed to reinforce habits that prevent those errors:

• Write known values clearly and label units.
• Select the method first before you calculate.
• Set up clean steps that are easy to check.
• Sanity-check the result before selecting an answer.

4) Use flash cards for daily consistency.
The fastest improvement often comes from steady repetition. Flash cards make it realistic to study every day—even if it’s only 10–15 minutes—so definitions, key concepts, and high-frequency NEC topics stay fresh.

5) Practice pacing like the real exam.
Because the Electrical Contractor exam is 4 hours for 100 scored items (plus pretest items), you can’t afford to over-read long sections of code. Train a simple rhythm: identify → locate → confirm → apply → answer → move.

A realistic weekly routine many working electricians can maintain:

• 3 days/week: Master Study Guide practice + NEC verification (60–90 minutes)
• 2 days/week: Calculations practice (45–75 minutes)
• Daily: Flash cards (10–15 minutes)
• Weekly: One mixed timed session that blends code questions and calculations

This keeps your prep balanced so you don’t become fast in the NEC but shaky on math—or the other way around.
