The C-2 Electrical Contractor exam is the trade half of a Nevada electrical license; the Contractor Management Survey (CMS) is the other half, and every NSCB applicant takes it. PSI's Nevada bulletin sets the C-2 format: 80 questions, a minimum passing score of 56, 4 hours, open book with the 2017 National Electrical Code and NFPA 72. Practice it in the free sample above: no sign-up, with a written explanation on every question.
The Nevada State Contractors Board requires every applicant, in every classification, to pass the Contractor Management Survey — the business-and-law exam — in addition to the trade exam for the classification applied for. PSI's Nevada bulletin gives the CMS 60 questions, a minimum passing score of 45 and 2 hours; the C-2 Electrical Contractor trade exam gets 80 questions, a minimum passing score of 56 and 4 hours. The bulletin prices one examination portion at $95 and two portions at $140, and notes the $140 rate applies when the second portion is the CMS. A candidate who tests unsuccessfully waits 2 weeks before retaking each portion, and a third failure voids the application — you then re-apply directly with the Board.
C-2 is an open-book exam, which candidates often hear as "bring your library." The bulletin allows exactly two references into the room: the National Electrical Code or the NEC Handbook, 2017 edition, and NFPA 72, the National Fire Alarm Code, 2010 or 2013. It then names what is NOT allowed, by title — Ugly's Electrical References and 29 CFR Part 1926, the OSHA construction standards. That last one matters, because Safety Information is eight of the eighty questions and you will be answering them from memory. The marking rules are just as strict: highlight, underline and index before the session, never write in the book, use permanent tabs only (Post-It notes must be removed), and bring no additional papers, loose or attached. For code questions the exam is based only on the edition listed, so a newer NEC is the wrong book.
PSI publishes the content outline as fifteen areas with an item count each, summing to 80: Conductors and Cables 8, Safety Information 8, Service, Feeders and Branch Circuits 7, Grounding and Bonding 7, Raceways and Boxes 7, General Electrical Knowledge 6, Electrical Power 6, Motors 6, Lighting 5, Special Occupancies and Equipment 5, Transmission Lines 5, Overcurrent Protection 4, Low Voltage 2, Illuminated Signs 2, and Fire Detection and Alarm Systems 2. Read that list as a study plan: the code-table work — conductors, grounding, raceways, overcurrent — is roughly a third of the exam, and the calculation areas (electrical power, motors) are another dozen questions where a formula and a calculator beat memory every time. The scope of the license itself is one sentence in the bulletin: a C-2 licensee may install any electrical wires, fixtures, appliances, apparatuses, raceways and conduits.
The safety questions come out of federal construction law, so 29 CFR 1926 Subpart K is the ground to cover: the pre-job survey for energized circuits and the warning-sign and employee-notification duties that go with it (1926.416(a)(3)), insulated protective gloves where the exact location of underground powerlines is unknown (1926.416(a)(2)), the staple/nail/wire prohibition on extension cords (1926.416(e)), lockout and tagging with tags at all points where a circuit can be energized (1926.417), the GFCI-or-assured-grounding-program choice for temporary receptacles (1926.404(b)(1)), and the prohibited uses of flexible cords (1926.405(g)(1)(iii)). Nevada adds a statute electricians hit every time they trench: NRS 455.110 requires notice to the association for operators at least 2 working days but not more than 28 calendar days before excavation, plus white-lining the area and cooperating with the utility operators — with a narrow emergency exception.
You test on a computer at a PSI center in Nevada and PSI forwards your result to the Board. The exam is offered in English and Spanish — the bulletin lists NV C-2 Electrical among the Spanish versions, and you switch by calling PSI at (855) 205-5827 or emailing examschedule@psionline.com. Registration fees are not refundable or transferable and expire with your eligibility. Applicants also submit fingerprints for a state and national criminal history record as part of licensure. Everything else — applications, classifications, monetary limits and bonds — is Board territory rather than PSI's, and the CMS course covers it; see the Nevada CMS practice test.
The full LICENA Nevada C-2 course is 500 questions across five blocks mapped to PSI's fifteen areas. At 30 questions a day that is about three weeks: one pass to find the gaps, a second pass on the areas you missed, then the timed final at 80 questions in 4 hours. Because the exam is open book, practice looking things up rather than memorizing — tab your 2017 NEC early and use the same tabs every time you study, so the index in your head matches the one in the book on test day. Do the power and motor calculations on paper. And read the explanation on every question you miss: the exam rewords facts, and remembering answer letters buys you nothing.
