- NV-C2 is PSI's 80-question, 240-minute trade exam for Nevada's Electrical Contractor (C-2) classification.
- A passing score requires 56 correct answers out of 80, or 70%.
- Conductors and Cables and Safety Information are tied as the largest tested domains.
- Licensure also requires the CMS exam, Board approval, and four years of qualifying experience within the prior 15 years.
What NV-C2 Actually Is
NV-C2 refers to the Nevada Electrical Contractor (C-2) Trade Exam, the trade competency examination that the Nevada State Contractors Board requires as part of qualifying for a C-2 contractor's license. This is not a generic industry credential or a training certificate - it is a state licensing exam tied specifically to the classification that governs electrical wiring, fixtures, appliances, apparatuses, raceways, and conduit installation work performed under a Nevada contractor's license.
If you're researching what this exam covers, how it's scored, or how it fits into the broader licensing process, this article walks through the mechanics as they apply specifically to NV-C2, not to any other credential that happens to share the same abbreviation.
Who Administers the Exam
The Nevada State Contractors Board owns the C-2 classification and sets the licensing requirements, but the actual trade examination is administered by PSI, a third-party testing provider. PSI delivers the exam content, manages scheduling, and reports scores back to the Board. Understanding this split matters because fee payments, exam scheduling, and content outlines all flow through PSI's system, while approval of your license application, verification of experience, and issuance of the license itself remain Board functions.

Exam Format and Scoring
The NV-C2 trade exam is a closed-book, multiple-choice test with a fixed structure:
- 80 questions, all multiple-choice
- 240 minutes allotted to complete the exam
- 56 correct answers required to pass, equal to 70%
The Board classifies the exam as closed book, with one important exception: code references are permitted only when they're expressly authorized by the current PSI content outline for the exam. In practice, this means candidates should confirm exactly which reference materials are allowed at the time they schedule, rather than assuming any code book can be brought into the testing center. Because the allowed references and their edition can change with the outline, it's worth reviewing this detail close to your test date rather than relying on outdated information.

Key Takeaway
With 80 questions and a 56-correct threshold, you can miss 24 questions and still pass - but with the two largest domains covering Conductors and Cables and Safety Information, those are the last areas you want to guess on.
The 15 Content Domains
The NV-C2 outline is organized into 15 domains covering the full scope of electrical contracting knowledge tested under this classification:
- General Electrical Knowledge
- Service, Feeders, and Branch Circuits
- Grounding and Bonding
- Conductors and Cables
- Raceways and Boxes
- Special Occupancies and Equipment
- Electrical Power
- Motors
- Low Voltage
- Lighting
- Illuminated Signs
- Fire Detection and Alarm Systems
- Safety Information
- Transmission Lines
- Overcurrent Protection
Two domains - Conductors and Cables and Safety Information - are tied as the largest content areas on the exam. That means questions drawn from these two domains will make up a disproportionate share of your 80 questions compared to smaller domains like Illuminated Signs or Transmission Lines.
Conductors and Cables
Candidates need working command of conductor sizing, ampacity considerations, cable types and their applications, and the installation rules that govern how conductors are run, terminated, and protected.
- Expect heavier weighting here than almost any other domain
- Prioritize this domain early in your study sequence
Safety Information
This domain covers the safety practices, hazard awareness, and protective procedures relevant to electrical contracting work - material that tends to show up in scenario-based questions rather than pure definitions.
- Tied with Conductors and Cables for the largest share of questions
- Don't treat this as "common sense" filler - it's tested in depth
Because domain weighting directly affects how you should allocate study time, it's worth reading a full breakdown of all 15 areas before building a study calendar. See NV-C2 Exam Domains 2026: Complete Guide to All 15 Content Areas for domain-by-domain detail.
Licensure Requirements Beyond the Exam
Passing the NV-C2 trade exam is one piece of a larger licensing puzzle. To actually hold a C-2 contractor's license in Nevada, the Board also requires:
- Board approval of the contractor license application
- The CMS exam (Contractors Management Survey), which can be scheduled together with the trade exam through PSI
- A qualifying individual with four years of relevant experience earned within the prior 15 years
- Approved education, which may substitute for up to three of those four required years
This structure means the exam itself is not the finish line - it's a gate that sits alongside experience verification and CMS completion. Candidates sometimes assume passing the trade exam equals licensure, but the Board's approval process and the qualifying individual's experience history are evaluated independently.
What C-2 Contractors Are Licensed to Do
The C-2 classification authorizes the installation of electrical wires, fixtures, appliances, apparatuses, raceways, and conduits. This scope is the practical reason the exam is structured the way it is - the domain list mirrors real installation work: wiring methods, service and feeder sizing, grounding and bonding practices, raceway installation, and specialty areas like signs, alarm systems, and low-voltage work.
Because licensure is tied so directly to scope of work, understanding how the domains map onto actual jobsite tasks helps make abstract exam questions feel concrete. A question about overcurrent protection, for instance, isn't testing trivia - it's testing whether you'd correctly size and protect a circuit you'd actually install under this license.
Fees and Scheduling Mechanics
PSI's exam fees for NV-C2 are straightforward but worth planning around:
| Scheduling Option | PSI Fee |
|---|---|
| Trade exam only | $95 |
| Trade exam scheduled together with CMS | $140 |
Beyond the exam fees, the Board charges a $300 application fee and a $600 biennial license fee once you're approved. Nevada contractor licenses are issued on a biennial basis, meaning renewal and the associated fee structure recur every two years rather than annually.
For a full accounting of every fee involved from application through renewal, see NV-C2 Certification Cost 2026: Complete Pricing Breakdown.
Who Hires C-2 Electricians
A Nevada C-2 license is typically sought by electricians moving from journeyman-level work into contracting - either to run their own electrical contracting business or to qualify as the licensed individual for an employer's contracting operation. Because the classification covers general electrical installation work rather than a single niche, C-2 license holders commonly work across residential, commercial, and light industrial projects that require wiring, fixtures, service and feeder work, and related installations.
If you're weighing whether pursuing this license lines up with your career goals, it helps to look at both the job market and the return on the licensing investment.

Building a Domain-Based Study Plan
Generic study advice only goes so far with a 15-domain, closed-book exam like this one. What matters more is sequencing your review around domain weight and question count. Since Conductors and Cables and Safety Information are tied as the largest domains, they deserve the earliest and most repeated attention in any study calendar, with the remaining 13 domains rotated through in decreasing order of expected weight.
Anchor the Largest Domains
- Work through Conductors and Cables in depth
- Pair it with Safety Information, since both carry the heaviest question share
Core Installation Domains
- Service, Feeders, and Branch Circuits
- Grounding and Bonding
- Raceways and Boxes
- Overcurrent Protection
Specialty and Lower-Frequency Domains
- Motors, Lighting, Low Voltage, Special Occupancies
- Illuminated Signs, Fire Detection and Alarm Systems, Transmission Lines, Electrical Power, General Electrical Knowledge
Timed practice matters as much as content review given the 240-minute window across 80 questions - that's an average of three minutes per question, which is generous if you know the material but tight if you're still working out fundamentals mid-exam. A structured walkthrough of how to convert study time into exam-day readiness is covered in NV-C2 Study Guide 2026: How to Pass on Your First Attempt.
Practicing under realistic, timed conditions with questions modeled on the actual domain breakdown is one of the most direct ways to gauge readiness before exam day. You can start building that habit with a full practice test that mirrors the domain structure described above.
How the Exam Actually Feels to Take
On paper, 70% sounds achievable, and with 240 minutes for 80 questions, time pressure is rarely the biggest obstacle for well-prepared candidates. The harder part is breadth - 15 distinct domains means you can't cram a narrow slice of content and expect to clear the passing threshold, especially with Conductors and Cables and Safety Information both weighted heavily. Candidates who treat every domain as equally worth reviewing, rather than weighting their prep toward the largest domains, often find themselves under-prepared in the two areas most likely to determine their score. A closer breakdown of where candidates tend to struggle is available in How Hard Is the NV-C2 Exam? Complete Difficulty Guide 2026.
Reviewing realistic practice questions against the full domain list before you schedule your exam date is one of the more reliable ways to identify weak spots while there's still time to address them.
