What NV-C2 Stands For
NV-C2 stands for the Nevada Electrical Contractor (C-2) Trade Exam, the trade competency test that the Nevada State Contractors Board requires as part of the licensing process for the C-2 electrical classification. The exam itself is written and delivered by PSI, the testing vendor the Board contracts with for trade examinations across multiple license classifications, not just electrical work.
The "C-2" designation is Nevada's specific classification code for this scope of electrical contracting work, and the exam tied to it is simply referred to as the NV-C2 exam by candidates, instructors, and prep resources - including this site. If you're just starting to research what this credential involves at a broader level, our What Is NV-C2? and NV-C2 Meaning pages walk through the basics in plain language before you dive into exam mechanics.
Who Oversees the C-2 Exam
The Nevada State Contractors Board sets the licensing requirements, and PSI administers the actual trade examination on the Board's behalf. This two-party structure matters for candidates: the Board approves your application and qualifying experience, while PSI handles scheduling, proctoring, scoring, and exam-day logistics. Understanding this split helps you know where to direct questions - licensing eligibility questions go to the Board, scheduling and testing-day questions go to PSI.
Because the Board classifies trade exams as closed book, PSI's exam-day rules only permit code references that are expressly authorized by the current PSI content outline for the C-2 exam. This is a detail candidates frequently misunderstand, assuming they can bring any code book they like - you can't, so it's worth confirming exactly what's allowed before your appointment.
What the C-2 Classification Covers
The C-2 classification authorizes installation of electrical wires, fixtures, appliances, apparatuses, raceways, and conduits. That scope is broad by design, which is why the trade exam spans 15 separate domains rather than a narrow slice of electrical work. A contractor holding this license is expected to demonstrate competency across residential, commercial, and specialty electrical installation topics - not just one niche area.
This breadth is one reason candidates sometimes underestimate the exam. If you're weighing how much preparation time to budget, our guide on How Hard Is the NV-C2 Exam? breaks down where most of the difficulty actually comes from.
Exam Format and Scoring
The NV-C2 trade exam consists of 80 multiple-choice questions, and candidates are given 240 minutes to complete it. To pass, you need 56 correct answers, which works out to 70%. There's no partial credit or weighted scoring described beyond that raw percentage - you either hit the threshold or you don't.
- Question format: Multiple-choice only
- Question count: 80
- Time allowed: 240 minutes
- Passing score: 56 correct answers (70%)
- Book policy: Closed book, except code references PSI's content outline expressly authorizes

Key Takeaway
With 240 minutes for 80 questions, you have roughly three minutes per question on average - enough time to reread tricky items, but not enough to treat the exam casually.
The 15 Content Domains
The PSI content outline for the NV-C2 exam is organized into 15 domains. Two of them - Conductors and Cables, and Safety Information - are tied as the largest domains, meaning they carry more weight than any single other area on the outline. That doesn't mean the other domains are optional; it means your study time should be allocated with those two in mind first.
Domain 4: Conductors and Cables
One of the two largest domains. Candidates should be comfortable with conductor sizing, cable types, ampacity considerations, and installation methods.
- Frequently tested alongside overcurrent protection concepts
- Expect application-style questions, not just definitions
Domain 13: Safety Information
Tied for the largest domain on the outline. This area covers the safety principles that run through nearly every other domain, from grounding to equipment handling.
- Don't treat this as a "common sense" domain - it's tested specifically
- Cross-references with grounding, bonding, and overcurrent protection questions
The remaining 13 domains cover the full scope of C-2 work:
- Domain 1: General Electrical Knowledge
- Domain 2: Service, Feeders, and Branch Circuits
- Domain 3: Grounding and Bonding
- Domain 5: Raceways and Boxes
- Domain 6: Special Occupancies and Equipment
- Domain 7: Electrical Power
- Domain 8: Motors
- Domain 9: Low Voltage
- Domain 10: Lighting
- Domain 11: Illuminated Signs
- Domain 12: Fire Detection and Alarm Systems
- Domain 14: Transmission Lines
- Domain 15: Overcurrent Protection

Fees, Registration, and CMS
PSI charges $95 to sit for the trade exam alone. If you schedule the trade exam and the CMS (business and law exam component required for licensure) together, the combined fee is $140. Scheduling them together can simplify your testing timeline, but make sure you're prepared for both content areas at once if you go that route.
| Scheduling Option | Fee |
|---|---|
| Trade exam only | $95 |
| Trade exam + CMS together | $140 |
These PSI testing fees are separate from the Board's licensing fees, covered next.

Licensure Requirements After Passing
Passing the trade exam is one piece of a larger licensing process. To actually hold a C-2 license in Nevada, you need:
- Board approval of your application
- A passing CMS score (the business and management exam component)
- A qualifying individual with four years of relevant experience earned within the prior 15 years
- Approved education can substitute for up to three of those four required years
Once licensed, Nevada contractor licenses operate on a biennial cycle. The Board charges a $300 application fee and a $600 biennial license fee to maintain that status. These are recurring costs to budget for beyond your initial exam fees. For the complete eligibility breakdown, including how experience and education substitutions work, see NV-C2 Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Who Actually Needs This Exam
The NV-C2 exam is aimed at individuals seeking to qualify a business for the C-2 electrical contractor classification in Nevada - typically working electricians moving into contracting, business owners adding a qualifying individual, or experienced tradespeople formalizing their ability to legally bid and perform electrical installation work covered under this classification. It's not a certification pursued for its own sake; it's a required step tied directly to Nevada contractor licensing.

A Focused Way to Prepare
Given that 80 questions cover 15 domains in 240 minutes, a scattershot approach to studying tends to waste time on areas that carry little weight. Since Conductors and Cables and Safety Information are tied as the largest domains, it makes sense to schedule dedicated review blocks for those two areas early, then layer in the remaining 13 domains in the weeks that follow.
Conductors and Cables + Safety Information
- Work through conductor sizing, ampacity, and cable installation rules
- Review safety principles that intersect with grounding and overcurrent protection
Core Installation Domains
- Service, Feeders, and Branch Circuits
- Grounding and Bonding, Raceways and Boxes, Overcurrent Protection
Specialty Domains
- Motors, Low Voltage, Lighting, Illuminated Signs
- Fire Detection and Alarm Systems, Transmission Lines
Timed Practice and Review
- Full-length practice runs under a 240-minute limit
- Revisit weak domains identified during practice
