Introduction
The NCCER Electrical Level 2 Certification Exam is designed to assess the intermediate
knowledge and practical skills required for transitioning from a trainee to a journeyman
electrician. This comprehensive assessment focuses on the application of the National
Electrical Code (NEC) across diverse tasks including advanced conduit bending, motor
theory, and complex lighting systems. The exam utilizes a multiple-choice and scenario-
based format to evaluate a candidate's ability to solve technical problems, ensure regulatory
compliance, and make professional decisions in real-world electrical environments. Success
requires a deep understanding of foundational electrical theory combined with the rigorous
safety and ethics standards essential for the trade.
SECTION ONE: QUESTIONS 1-100
1. In a purely resistive AC circuit, what is the relationship between the current and the
voltage?
, A. Current leads voltage by 90 degrees
B. Current lags voltage by 90 degrees
🔴 C. Current and voltage are in phase
D. Current leads voltage by 180 degrees
🔵 Explanation: In a purely resistive circuit, there is no reactance to cause a phase
shift, so the peaks and zero-crossings of voltage and current occur simultaneously.
2. Which of the following is the correct formula for calculating the total capacitance of
three capacitors connected in parallel?
A. 1/Ct = 1/C1 + 1/C2 + 1/C3
🔴 B. Ct = C1 + C2 + C3
C. Ct = (C1 × C2 )/C3
D. Ct = C1 + (C2 × C3 )
🔵 Explanation: Capacitors in parallel are added directly together to find the total
capacitance, unlike resistors in parallel.
3. When bending conduit, what is the "multiplier" for a 30-degree offset?
A. 1.41
🔴 B. 2.0
C. 2.6
D. 3.86
, 🔵 Explanation: The constant multiplier for a 30-degree bend is 2.0. To find the
distance between bends, you multiply the offset rise by 2.
4. What type of AC motor uses a centrifugal switch to disconnect the start windings once
the motor reaches approximately 75% of its rated speed?
A. Shaded-pole motor
🔴 B. Split-phase motor
C. Three-phase squirrel cage motor
D. Synchronous motor
🔵 Explanation: Split-phase motors use a centrifugal switch to drop out the start
winding once the rotor gains enough momentum to run on the main winding.
5. According to the NEC, what is the maximum number of degrees of bends allowed
between pull points in a single run of conduit?
A. 180 degrees
B. 270 degrees
🔴 C. 360 degrees
D. 540 degrees
🔵 Explanation: NEC Section 358.26 states that there shall not be more than the
equivalent of four quarter bends (360 degrees total) between pull points.
