Introduction
This comprehensive practice examination is designed to rigorously assess the
knowledge and skills essential for professionals in the electric vehicle infrastructure
sector. The test encompasses a wide range of topics, from fundamental electrical
theory and NEC compliance to advanced concepts in load management and grid
integration. Candidates will encounter both direct knowledge-based multiple-choice
questions and complex scenario-based items that require the application of
technical expertise, critical thinking, and sound professional judgment. The
emphasis throughout is on real-world application, decision-making under
constraints, and adherence to the highest standards of safety and regulatory
compliance. This test bank serves as a vital tool for final preparation and self-
assessment, mirroring the depth and breadth of the actual certification
examination.
,SECTION ONE: QUESTIONS 1 – 50
1. A Level 2 EVSE unit is rated at 240V, 32A continuous. What is the minimum
branch circuit rating required for this equipment?
A. 30A
B. 32A
C. 40A
D. 50A
🟢 Correct Answer: C. 40A
🔴 Explanation: The NEC requires the branch circuit for continuous loads to be
sized at 125% of the continuous load. 32A × 125% = 40A.
2. Which of the following is the MOST significant advantage of an EVSE with
bidirectional power flow capability?
A. It can charge the EV battery at a faster rate.
B. It allows the EV battery to supply power back to the grid.
C. It reduces the overall cost of the EVSE unit.
D. It simplifies the installation process.
🟢 Correct Answer: B. It allows the EV battery to supply power back to the grid.
🔴 Explanation: Bidirectional capability, or Vehicle-to-Grid (V2G), allows the EV
battery to act as an energy source, providing power to the grid or a building,
which is its primary defining advantage over unidirectional units.
3. When performing a voltage drop calculation for an EVSE circuit, which value
is used for the current in the formula?
A. The nameplate-rated current of the EVSE.
B. The maximum current the EVSE can draw, including any overcurrent allowance.
,C. The calculated load after applying the 125% continuous load factor.
D. The utility's maximum available fault current.
🟢 Correct Answer: C. The calculated load after applying the 125% continuous
load factor.
🔴 Explanation: Voltage drop calculations must be based on the actual calculated
load current on the circuit, which for continuous loads like EVSE, is the nameplate
current multiplied by 125%.
4. A GFCI protection device for an EVSE is primarily designed to protect against
which hazard?
A. Overcurrent conditions
B. Short-circuit faults
C. Electric shock from ground faults
D. Lightning strikes
🟢 Correct Answer: C. Electric shock from ground faults
🔴 Explanation: GFCI, or Ground-Fault Circuit Interrupter, is a safety device
designed to protect people from electric shock by rapidly opening the circuit
when it detects a current imbalance (leakage) to ground.
5. What is the primary function of the "pilot signal" in a standard SAE J1772
charging interface?
A. To carry high-voltage AC power to the vehicle.
B. To establish a communication link for billing purposes.
C. To establish the vehicle's state of charge and communicate it to the utility.
D. To communicate the EVSE's current capacity and allow for vehicle
authorization.
, 🟢 Correct Answer: D. To communicate the EVSE's current capacity and allow for
vehicle authorization.
🔴 Explanation: The pilot signal is a control pilot wire that the EVSE uses to
indicate its maximum current capacity to the EV and to detect the vehicle's
presence and readiness to charge.
6. Before manually disconnecting an EVSE from the utility grid, the technician
must FIRST ensure:
A. The EV is fully charged.
B. The local disconnect is locked and tagged.
C. The EVSE is turned off at its internal breaker.
D. The meter is removed.
🟢 Correct Answer: B. The local disconnect is locked and tagged.
🔴 Explanation: The first step in any lockout/tagout (LOTO) procedure is to
identify and verify all energy sources, then physically isolate the equipment using
a lockable disconnect switch with a lock and tag. This ensures the circuit remains
de-energized.
7. In an EVSE, the term "duty cycle" of the pilot signal refers to:
A. The number of charge/discharge cycles the battery can withstand.
B. The ratio of time the pilot signal voltage is high to the total period.
C. The maximum current the circuit can safely carry over a 24-hour period.
D. The total time the EVSE is active per day.
🟢 Correct Answer: B. The ratio of time the pilot signal voltage is high to the total
period.
🔴 Explanation: The duty cycle of the PWM (Pulse-Width Modulated) pilot signal
is the percentage of time the signal is in its "high" state during a complete cycle.
