What Is NV-C2 Certification?
NV-C2 refers to the Nevada State Contractors Board's C-2 trade examination, the licensing exam that qualifies an individual to hold the Electrical Contractor (C-2) classification in Nevada. This is not a private certificate you print and frame - it's a state-mandated trade competency exam tied directly to your ability to legally contract electrical work in Nevada. The exam is administered by PSI, the third-party testing vendor the Board contracts with to deliver both the trade exam and the Contractor's Management Survey (CMS) required for licensure.
If you're new to the process, start with our overview of what NV-C2 is and how the acronym is used across Nevada's licensing system, or review NV-C2 requirements before you commit to a testing date.
Who Administers the Exam and How Licensing Works
The Nevada State Contractors Board owns the licensing requirements; PSI delivers the actual exam sessions. This split matters for candidates because registration, fees, and scheduling logistics run through PSI, while eligibility determinations, license classification, and final approval run through the Board.
To become a licensed C-2 contractor, you need more than a passing exam score. The Board also requires:
- Board approval of your application as a qualifying individual
- Passing the CMS (Contractor's Management Survey), a separate exam from the trade exam
- Four years of relevant electrical experience earned within the prior 15 years
- Optional substitution of approved education for up to three of those four years
This structure means passing the trade exam is a necessary milestone, not the finish line. For a full breakdown of every eligibility component, see our detailed NV-C2 requirements guide.
Key Takeaway
Budget time for both the trade exam and the CMS - many candidates schedule them together at PSI to save a trip and reduce combined cost.
Exam Format: Questions, Time, and Passing Score
The NV-C2 trade exam is a closed-book, multiple-choice test with a fixed structure:
- 80 questions, all multiple-choice
- 240 minutes (4 hours) to complete the exam
- 56 correct answers required to pass, equal to 70%
The Board classifies the trade exam as closed book, with one notable exception: code references that are expressly authorized by the current PSI content outline. In practice, this means you may be allowed to bring specific, approved code references into the testing room - but only the ones listed on the outline for your exam version, not any code book you choose. Always confirm the current authorized reference list before test day rather than assuming.
Because the passing threshold is fixed and the question count is fixed, every domain effectively carries weight toward that 56-question target. For the exact scoring mechanics and what a 70% threshold means in practice, read our dedicated post on the NV-C2 passing score.
| Exam Element | Detail |
|---|---|
| Question format | 80 multiple-choice questions |
| Time allowed | 240 minutes |
| Passing score | 56 correct (70%) |
| Book policy | Closed book, except code references authorized by the current PSI outline |
| Administered by | PSI, on behalf of the Nevada State Contractors Board |
Before you sit for the exam, it's worth reading a candid assessment of how hard the NV-C2 exam actually is so your prep time is calibrated correctly, and checking current NV-C2 exam dates to plan your registration window.
The 15 NV-C2 Content Domains
PSI's content outline for the C-2 trade exam is organized into 15 domains. Two of them - Conductors and Cables, and Safety Information - are tied as the largest domains on the exam, meaning they deserve the most study time relative to the others.
Domain 4: Conductors and Cables
One of the two largest domains. Expect questions on conductor sizing, ampacity, cable types, insulation ratings, and application rules for different conductor materials.
- Ampacity adjustment and correction factors
- Conductor identification and color coding
- Cable types permitted for specific installation conditions
Domain 13: Safety Information
Tied for the largest domain. Covers the safety-related knowledge every C-2 contractor must apply on the job, from working clearances to hazard recognition.
- Working space and clearance requirements
- Warning labels and equipment marking
- General jobsite safety practices tied to electrical work
The remaining 13 domains round out the outline: General Electrical Knowledge, Service Feeders and Branch Circuits, Grounding and Bonding, Raceways and Boxes, Special Occupancies and Equipment, Electrical Power, Motors, Low Voltage, Lighting, Illuminated Signs, Fire Detection and Alarm Systems, Transmission Lines, and Overcurrent Protection. Each represents a distinct slice of the 80-question exam, and none should be skipped entirely - a candidate who ignores a smaller domain can still lose enough points to miss the 56-correct threshold.
For a domain-by-domain breakdown with study priorities for each of the 15 areas, see our complete NV-C2 exam domains guide.
What the C-2 Classification Actually Covers
The C-2 classification defines the legal scope of work for licensees: installation of electrical wires, fixtures, appliances, apparatuses, raceways, and conduits. This scope explains why the exam domains lean so heavily toward conductors, raceways, boxes, and the equipment those wires ultimately serve - lighting, signs, alarm systems, and motors are all downstream of the core wiring and raceway work the license authorizes.
Understanding this scope also clarifies why domains like Illuminated Signs and Fire Detection and Alarm Systems appear alongside more fundamental topics like Grounding and Bonding - a C-2 contractor is expected to install and terminate wiring for a wide range of end-use equipment, not just run cable.
Fees and Cost Mechanics
PSI's exam fees are straightforward:
- $95 for the trade exam scheduled alone
- $140 when the trade exam and CMS are scheduled together
Beyond the exam fee itself, licensure carries separate Board-level costs: a $300 application fee and a $600 biennial license fee, since Nevada contractor licenses run on a two-year renewal cycle. These are cumulative costs across the path to licensure, not alternatives to the exam fee - candidates should budget for testing costs and Board fees separately.
For a full cost breakdown including how these fees stack up across a licensing timeline, see our NV-C2 certification cost guide. If you're weighing whether the investment pays off, our ROI analysis on NV-C2 walks through the qualitative case for pursuing the license.
Key Takeaway
Scheduling the trade exam and CMS together at PSI costs $140 combined versus $95 for the trade exam alone - factor the CMS timing into your plan rather than treating it as an afterthought.
Who Hires C-2 Licensees
Employers and contracting firms that need someone who can legally pull permits and take responsibility for electrical wiring, fixture, and raceway installation seek out C-2-licensed individuals. This includes electrical contracting companies bidding on residential and commercial installation work, firms handling tenant improvements that require new circuits or fixtures, and businesses installing signage, low-voltage systems, or fire alarm wiring that falls under the C-2 scope. Because the license ties directly to a qualifying individual's experience and exam performance, it's frequently the credential a company relies on to legally operate as an electrical contractor in Nevada.

How to Approach Preparation
Given the exam's structure - 80 questions, 240 minutes, and a 70% passing threshold across 15 domains - an effective study plan allocates the most hours to Conductors and Cables and Safety Information first, then works through the remaining domains in rotation rather than cramming them at the end.
Conductors, Cables, and Safety Information
- Review ampacity tables and conductor sizing rules
- Study working clearance and safety marking requirements
- Take practice questions focused only on these two domains
Core Installation Domains
- Grounding and Bonding, Raceways and Boxes, Overcurrent Protection
- Service, Feeders, and Branch Circuits calculations
- Cross-reference authorized code sections allowed under the closed-book exception
Remaining Domains and Full Simulation
- Motors, Lighting, Low Voltage, Illuminated Signs, Fire Detection, Transmission Lines, Electrical Power, Special Occupancies
- Run timed 80-question practice sets to build stamina for the 240-minute limit
- Identify remaining weak domains and revisit them one final time
Repetition tied to the exam's actual weighting works better than generic study advice. Space out review sessions across weeks rather than one long cram, and prioritize practice questions that mirror the real 80-question, multiple-choice format. For a structured walkthrough of this entire process, our NV-C2 study guide goes deeper into pacing and resource selection, and our NV-C2 cheat sheet is useful for last-week review of must-know facts across all 15 domains.
Running full-length timed practice exams on our practice test platform is one of the most direct ways to gauge whether you're on pace to hit 56 correct answers within the 240-minute window. Reviewing missed questions by domain on the practice site also helps you see exactly where your weak spots sit relative to the two largest domains.
