Nevada (NV) C-7 Elevation & Conveyance Contractor Practice Exam
Exam Coverage Summary
Based on Nevada State Contractors Board (NSCB) requirements and the C-7 exam blueprint,
this practice exam covers:
• Licensing & Regulatory Framework: NAC 624.250 defines the C-7 scope; a single C-7
license covers all four subclassifications (C-7a Elevator/Dumbwaiter, C-7b
Escalator/Conveyor, C-7c Pneumatic Tube, C-7d Moving Walkway). Qualifying
individuals need 4 years of experience within the preceding 10 years as a journeyman,
foreman, supervisor, or contractor. Licenses are biennially renewable with continuing
education requirements.
• Primary Safety Code: ASME A17.1/CSA B44 is the primary safety code for elevators,
escalators, moving walks, dumbwaiters, and lifts.
• Fire Safety Requirements: Hoistway walls in high-rise buildings require a 2-hour
fire-resistance rating. Firefighter's Emergency Operation (FEO) has two phases: Phase I
recalls cars to a designated floor; Phase II permits fire department operation.
• Elevator Systems: Traction elevators (geared/gearless) use sheaves and ropes; gearless
machines provide direct connection for smoother operation. Hydraulic elevators include
direct plunger and holeless designs; anti-creep devices maintain car level during loading.
Safety gear engages when governor trips; factor of safety for wire rope is typically 5.0.
• Escalator Systems: Safety devices include skirt obstruction switches, comb-plate impact
sensors, step-level sensors, and step chain break switches; handrail speed monitors
trigger emergency stop if mismatch exceeds 15%. Handrail height minimum is 36 inches
above step surface.
• Electrical & Controls: Traction motors typically operate on 480 V three-phase AC. NEC
Article 620 governs elevator electrical requirements; dedicated branch circuits required
for car lighting. Selective Collective operation groups cars based on passenger demand.
• Testing & Inspections: Category 1 (annual) testing includes visual and functional checks;
Category 5 (five-year) requires full-load/full-speed safety and buffer impact tests.
,Page 2 of 152
Acceptance testing must demonstrate emergency communication, safety systems, and
fire-rated assemblies.
• Safety: OSHA fall protection required at 6 feet or above; pit entry requires verifying stop
switches, ladder locks, and EPO buttons; permit-required confined space entry requires
atmospheric testing and permit.
• Recordkeeping: Service logs must be retained for at least 5 years on-site.
