INTRODUCTION
The Nevada C-2 Electrical Contractor examination assesses the
knowledge, skills, and judgment required to perform electrical
contracting work safely and in compliance with state law and the
National Electrical Code. The exam evaluates foundational
electrical theory, applied load calculations, regulatory compliance,
ethical business practices, and real-world decision-making through
,multiple-choice and scenario-based questions. Candidates must
demonstrate competency in interpreting code requirements,
managing project risks, and applying professional standards to
protect public safety and uphold the integrity of the electrical
contracting profession.

, Question 4
A balanced 480-volt, three-phase load draws 72 amperes at a
lagging power factor of 0.86. What is the real power consumed by
this load?
A. 29.7 kW
B. 51.5 kW
C. 59.9 kW
D. 69.1 kW
B. 51.5 kW
RATIONALE: Three-phase real power is calculated as P = 1.732 ×
V × I × PF. Substituting the values: 1.732 × 480 × 72 × 0.86 = 51,480
watts, or approximately 51.5 kW.
Question 5
What is the primary purpose of a performance bond in a
