Introduction
This comprehensive examination is designed to rigorously assess the knowledge and
practical skills essential for a certified Electric Vehicle Infrastructure Technician
(EVITP). It evaluates foundational electrical theory, a deep understanding of EVSE
technologies, and the application of the National Electrical Code. The exam uses a
scenario-based, multiple-choice format to test critical thinking and decision-making
skills in real-world installation and troubleshooting contexts. Successful candidates
will demonstrate their ability to integrate technical expertise with professional
ethics and safety to deliver effective and compliant EV charging solutions. This test
bank serves as the primary tool for final preparation, ensuring candidates are ready
for the certification exam.
SECTION ONE: QUESTIONS 1 – 100
,Question 1
What is the primary function of a Ground Fault Circuit Interrupter (GFCI) in an
Electric Vehicle Supply Equipment (EVSE) circuit?
A. To protect the EVSE from overcurrent damage.
B. To prevent electric shock by interrupting the circuit when a ground fault is
detected.
C. To monitor the insulation resistance of the EV charging cable.
D. To communicate the maximum available current to the electric vehicle.
🟢 B. To prevent electric shock by interrupting the circuit when a ground fault is
detected.
🔴 Explanation: A GFCI's primary purpose is protecting people from electric
shock by detecting an imbalance between the hot and neutral conductors, which
indicates a current leak to ground. It is not a primary overcurrent protection
device (that is the breaker), it doesn't monitor cable insulation (that's a separate
function), and it doesn't communicate with the EV.
Question 2
According to the NEC, what is the minimum conductor ampacity required for a
branch circuit supplying a continuous load of 48 amperes?
A. 48 A
B. 52.8 A
C. 60 A
D. 72 A
🟢 C. 60 A
🔴 Explanation: The NEC requires that conductors for continuous loads be sized
at 125% of the continuous load. 48 A x 1.25 = 60 A. While a 60A breaker is used,
the conductor must have an ampacity of at least 60A.
,Question 3
An EVITP technician is performing a site assessment. What is the MOST critical
information to document regarding the existing electrical service?
A. The age of the building.
B. The brand name of the main service panel.
C. The total available amperage and the current load on the service.
D. The distance from the panel to the proposed charger location.
🟢 C. The total available amperage and the current load on the service.
🔴 Explanation: A load calculation, which requires knowing the existing service
capacity and current load, is the most critical step to determine if the service can
support the additional load of an EV charger without causing an overload. While
the other options are relevant, they are secondary to the electrical capacity
assessment.
Question 4
What type of communication protocol is commonly used for a “smart” EV charger
to connect to a local area network and the internet?
A. Modbus RTU
B. CAN bus
C. Wi-Fi / Ethernet
D. PLC (Power Line Communication)
🟢 C. Wi-Fi / Ethernet
🔴 Explanation: Wi-Fi and Ethernet are the standard protocols used to connect
smart EVSEs to a network for internet access, enabling cloud connectivity, remote
monitoring, and over-the-air updates. Modbus is used for industrial equipment,
CAN bus is for in-vehicle communication, and PLC is used for communication
, over the power line itself, often between the EVSE and the EV, not for the building
network.
Question 5
A Level 2 EV charger is installed with a 40-ampere breaker and is designed to
deliver a maximum continuous output current of 32 amperes to the vehicle. This
is a standard and code-compliant installation. What is the calculated load for this
circuit?
A. 32 A
B. 40 A
C. 52 A
D. 28.8 A
🟢 A. 32 A
🔴 Explanation: The calculated load for a branch circuit is the actual continuous
load it is designed to serve. While the conductors and breaker must be sized for
125% of this load (32 A x 1.25 = 40 A), the load itself is defined as the continuous
current draw, which is 32 amperes.
Question 6
A technician observes a small cut in the outer jacket of an EV charging cable.
What is the MOST appropriate action?
A. Repair the cut with electrical tape.
B. Wrap the area with a self-fusing silicone tape.
C. Splice the cable and cover with heat shrink.
D. Remove the cable from service and replace it.
🟢 D. Remove the cable from service and replace it.
🔴 Explanation: Any damage to the outer jacket of an EV cable can compromise
its insulation and mechanical strength. As a safety-critical component, the cable
