- Special Installations or Constructions carries the most questions: eight of the 50.
- Each attempt costs USD 130, retakes included, and a failed exam requires a 30-day wait.
- The cut-score is not a pass rate; no authoritative current pass rate was verified for this exam.
The Official Cut-Score: What 70 Means
The Electrical General (2B) examination, a legacy IAEI-associated NCPCCI exam, publishes an official cut-score of 70. That is the number the testing program uses as the line between passing and not passing. If you are searching for the 2B passing score, that is the figure to plan around.
The bulletin for this exam publishes a cut-score but does not publish a worked conversion from raw questions to a final reported score. Because of that, this article does not tell you that a specific number of correct answers is guaranteed to clear the line. What you can say with confidence is how the exam is built: 50 four-option multiple-choice questions, two hours, open book. Treat 70 as the target and aim comfortably above it, with a margin that absorbs the questions you will inevitably find ambiguous or time-consuming.
Format and Mechanics Behind the Number
Understanding the delivery format tells you how the cut-score translates into real test-day pressure. Here are the verified specifics for the current 2B form.
| Feature | Electrical General (2B) |
|---|---|
| Official cut-score | 70 |
| Number of questions | 50 |
| Time allowed | Two hours |
| Question format | Four-option multiple choice |
| Delivery | Computer-based; open book |
| Fee | USD 130 per attempt, including retakes |
| Retake wait after a failed attempt | 30 days |
| Prequalifications to sit | None imposed by NCPCCI |
| Testing options | Prov testing centers or ExamRoom.AI remote proctoring |
Two hours for 50 questions averages to roughly two and a half minutes per item. That sounds generous until you remember that many of the questions require you to locate an article, table, or exception in the code book, then apply it. A load calculation or a conductor-sizing question can easily consume far more than the average, which means the straightforward questions must be answered quickly to bank time. For more on how the format shapes difficulty, see How Hard Is the 2B Exam? Complete Difficulty Guide 2026.
An on-screen calculator is provided on the exam. It handles basic arithmetic and square root. Do not assume you can bring any other calculator; confirm current rules in the candidate bulletin before test day.
Cut-Score vs. Pass Rate: Keeping Them Separate
This is one of the most commonly confused points around the 2B exam. The cut-score of 70 describes the standard a single candidate must meet. A pass rate describes what fraction of all candidates actually met it. They are different measurements, and one cannot be derived from the other.
No authoritative current empirical pass rate was verified for this exact examination. Be skeptical of any figure you see quoted without a clear source, and be especially wary of preparation-provider guarantees, which describe a vendor's marketing claim rather than independently verified exam statistics. If you want the full discussion of what is and is not known, read 2B Pass Rate 2026: What the Data Shows.
Where the 50 Questions Come From
The candidate bulletin publishes item counts for each of the 12 subject areas rather than percentage weights. The allocations total 50 questions. Here they are in official order.
| Domain | Subject Area | Questions |
|---|---|---|
| 1 | Cabinets, Panelboards, Switchboards, Boxes, and Conduit Bodies | 4 |
| 2 | Calculations of Load | 3 |
| 3 | Calculations of Wire Size | 3 |
| 4 | Conductors and Overcurrent Protection on the Load Side of the Service | 4 |
| 5 | Generators other than Dwellings | 1 |
| 6 | Lighting and Utilization Equipment | 4 |
| 7 | Motors other than Dwellings | 5 |
| 8 | Service Equipment and Conductors on the Supply Side of the Service | 5 |
| 9 | Special Installations or Constructions | 8 |
| 10 | Special Occupancies | 5 |
| 11 | Switches, Disconnects and Controllers | 3 |
| 12 | Wiring Methods | 5 |
These are official exam subject areas, not a preparation curriculum, and the counts describe how the exam is built rather than how you should divide your study hours. For a deeper walkthrough of each area, see 2B Exam Domains 2026: Complete Guide to All 12 Content Areas.
What the allocations imply about reaching 70
Because the exam has only 50 questions, each item carries real weight, and the distribution is uneven. A few observations follow directly from the counts:
- Special Installations or Constructions is the biggest single block. At eight questions, it is the largest allocation on the exam. Neglecting it leaves a large share of the exam exposed.
- Four areas sit at five questions each: Motors other than Dwellings, Service Equipment and Conductors on the Supply Side of the Service, Special Occupancies, and Wiring Methods. Together with Special Installations, these five areas account for 28 of the 50 questions.
- Generators other than Dwellings is the smallest block at one question. It is tempting to skip it entirely. That is a defensible trade-off if you are short on time, but remember that a single question can matter when you are near the line.
- The two calculation areas total six questions. Calculations of Load and Calculations of Wire Size are three questions each. They are time-intensive per question, so even a small block can drain your clock.
Domain 9: Special Installations or Constructions
The largest allocation on the exam, with eight questions. Because it spans specialized installations rather than one narrow topic, candidates need to be fast at locating the correct article in the code book instead of relying on memory alone.
- Practice finding the governing article quickly from a scenario description
- Pay attention to how special-installation rules modify or supplement general requirements
- Tab and highlight this section heavily, within the permitted reference rules
Domain 7: Motors other than Dwellings
Five questions that often blend lookup with calculation. Motor questions reward candidates who know where the relevant tables and conductor and protection rules live in the book.
- Rehearse the sequence from motor data to conductor sizing to protection and disconnecting means
- Keep your tabs consistent so you can move between related provisions without hunting
Why the Code Edition Governs Your Score
Your score depends on answering according to the specified code edition, not whichever edition you happen to know best. The candidate bulletin lists two forms: one based on NEC 2017 and one based on NEC 2020, with identical subject allocations. The 2020 form is the newer listed form, titled 2B Electrical General (2020 Code), using NFPA 70, National Electrical Code, 2020 edition.
The bulletin allows candidates to bring other editions of the same reference title, but the specified edition governs the answers. That is a trap. If you bring a different edition and read an answer from it, you may select a response that is correct under your edition but wrong for the exam.
Before you purchase a code book or a study guide, verify your booked form and match your references to it. Our 2B Study Guide 2026: How to Pass on Your First Attempt walks through selecting materials in more detail.
Open-Book Rules That Protect Your Score
Open book does not mean easy. It means the exam tests whether you can find and apply the code under time pressure. The reference rules directly affect how many questions you can answer correctly, so understanding them is part of understanding the passing score.
- Tabs and highlighting: Applicable approved references may be highlighted and permanently tabbed before testing. Do this ahead of time, and build a tabbing system you can navigate without thinking.
- NEC Handbook: The NEC Handbook is permitted where applicable. Check the bulletin's reference-rules appendix before test day to confirm what applies to your form.
- On-screen calculator: Basic arithmetic and square root only. Practice your load and wire-size calculations with that limitation in mind, since you will not have advanced functions.
- Remote testing: If you test through ExamRoom.AI remote proctoring, review the current Prov guidance on what is permitted at your desk, since requirements for a remote session differ from a testing center.
Key Takeaway
Do your tabbing and highlighting early, then take timed practice exams with your actual tabbed book. Familiarity with your own reference is the single biggest lever on an open-book exam with a two-hour limit.

What a Passing Score Does and Does Not Give You
Hitting 70 earns a passing result on the exam. It does not, by itself, give you a local license or certification. NCPCCI imposes no prequalifications to sit the exam, so there is no gate before you test, but passing alone does not make you licensed by a jurisdiction. Local licensing and employer requirements remain separate matters. For eligibility context, see 2B Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Identity and credential history
The exam is a legacy IAEI-associated NCPCCI examination. Earlier versions of the candidate bulletin named IAEI, now doing business as Independent Alliance of the Electrical Industry, as a partner. The current bulletin retains the 2B exam but omits IAEI from its partner list. Because of that, these exam specifications do not establish current IAEI credential issuance or renewal. IAEI's current ICC joint and CEI programs are separate routes with their own requirements.
The ICC E2 transition route
ICC's NCPCCI Reciprocity page, updated November 6, 2025, permits an E2 transition application using NCPCCI 2B, a supporting score report, and a current license. That route carries a separate fee and requires approval. A passing score is therefore an input to that application, not an automatic conversion. If this path matters to you, check the ICC page directly for the current process.

If You Miss the Mark: Retake Timing and Cost
Failing the first attempt is not the end of the road, but it does cost time and money. Each attempt, including retakes, is USD 130. A failed exam requires a 30-day wait before you can retake it. That waiting period is a planning variable: if you have a license application deadline or a job start date, build in enough room that a miss does not push you past it.
| Scenario | Cost | Timing |
|---|---|---|
| First attempt | USD 130 | Schedule when ready |
| Retake after a failed attempt | USD 130 (retakes are charged the same) | 30-day wait required |

Sequencing Your Preparation Around the Score
You do not need a generic study system. You need a plan that puts your time where the 50 questions are. One reasonable way to sequence the weeks, given the allocations above, is shown below. Adjust it to your own strengths.
Reference setup and the calculation areas
- Confirm your booked edition and buy the matching code book
- Tab and highlight, then work Calculations of Load and Calculations of Wire Size with only a basic calculator
The heavy hitters
- Special Installations or Constructions (eight questions)
- Motors other than Dwellings and Service Equipment and Conductors on the Supply Side of the Service (five each)
Installation-side coverage
- Special Occupancies and Wiring Methods (five each)
- Conductors and Overcurrent Protection on the Load Side of the Service, Lighting and Utilization Equipment, and Cabinets, Panelboards, Switchboards, Boxes, and Conduit Bodies (four each)
Gaps and timed full runs
- Switches, Disconnects and Controllers, and Generators other than Dwellings
- Full 50-question, two-hour practice runs using your tabbed book; review every miss by locating the governing article
The logic is simple: the calculation areas cost the most time per question, so build speed early, and the largest question blocks deserve the most repetition. Take timed runs on our 2B practice test and track whether your results sit comfortably above 70 rather than just touching it. For broader training options, see 2B Training.
Frequently Asked Questions
The official cut-score is 70. The exam has 50 four-option multiple-choice questions, a two-hour time limit, and is open book. The cut-score is the standard set for passing, and it is distinct from any statistic about how many candidates pass.
Each attempt costs USD 130, and retakes are charged at the same rate. After a failed attempt you must wait 30 days before retaking, so plan any deadlines with that wait in mind.
No. The passing score of 70 is the cut-score a candidate must meet. A pass rate would describe the share of all candidates who meet it. No authoritative current empirical pass rate was verified for this exam, so treat unsourced figures with caution.
No. Passing alone does not confer a local license or certification. NCPCCI imposes no prequalifications to sit the exam, but licensing is handled by local jurisdictions and employers set their own requirements.
The bulletin lists NEC 2017 and NEC 2020 forms with identical subject allocations, and the 2020 form is the newer one. The specified edition governs answers, so confirm your booked form first. An NEC 2023 study guide is preparation material and does not indicate a newer exam form.
