primarily responsible for delivering electrical power to the vehicle while providing the
required control and safety functions?
A. Traction inverter
B. EVSE
C. Battery management system
D. Regenerative braking controller
RATIONALE: EVSE provides the interface between the electrical supply and the electric vehicle,
incorporating conductors, connectors, control functions, and protective features necessary for
charging.
2. A technician is evaluating a proposed Level 2 charging installation at a commercial
facility. Which electrical characteristic should be established first when determining
whether the existing branch circuit can support the EVSE?
A. Available circuit voltage and ampacity
B. Vehicle paint color
C. Tire pressure
D. Battery state-of-charge
RATIONALE: The supply voltage and circuit ampacity determine whether the existing electrical
infrastructure can safely serve the proposed EVSE load.
3. During an EVSE installation, the installer discovers that the equipment grounding
conductor has been omitted from the branch circuit. What is the most appropriate action?
A. Install a larger neutral conductor instead
B. Proceed because the EVSE contains electronic protection
C. Correct the grounding arrangement before energizing the equipment
D. Reduce the charging current
RATIONALE: Proper equipment grounding is a fundamental safety requirement. Electronic
controls do not replace the required grounding and bonding provisions of the electrical
installation.
4. What is the primary purpose of the pilot/control communication used by many
conductive EV charging systems?
A. Increase the vehicle's battery voltage
B. Control and communicate charging conditions between the EVSE and vehicle
,2|Page
C. Operate the vehicle's headlights
D. Measure tire temperature
RATIONALE: The control system allows the EVSE and vehicle to establish charging status and
permissible charging conditions before and during charging.
5. A homeowner wants to install an EV charger in an attached garage. The proposed
installation is near an area where vehicles may physically contact the equipment. Which
consideration is especially important?
A. Decorative enclosure color
B. Mechanical protection and equipment placement
C. Vehicle audio system compatibility
D. Windshield size
RATIONALE: EVSE must be located and protected so that foreseeable vehicle impact and other
physical hazards do not compromise the installation.
6. An EVSE nameplate indicates a continuous charging load. Why must the branch-circuit
design account for the continuous nature of the load?
A. Charging loads are always intermittent
B. Continuous loads require appropriate sizing based on applicable electrical requirements
C. Continuous loads do not require overcurrent protection
D. Continuous loads eliminate the need for grounding
RATIONALE: EV charging can constitute a continuous load, so conductor, overcurrent
protection, and related equipment must be sized according to applicable continuous-load
requirements.
7. Which device is intended to interrupt current automatically when an overcurrent
condition occurs?
A. Circuit breaker
B. Pilot conductor
C. Proximity sensor
D. Charge connector
RATIONALE: Circuit breakers provide overcurrent protection by opening the circuit when
current exceeds their designed operating limits.
8. An installer is selecting conductors for an EVSE branch circuit. Which factor should
NOT be ignored when determining conductor suitability?
A. Conductor ampacity
B. Installation conditions
C. Terminal temperature limitations
D. Vehicle manufacturer's paint specification
,3|Page
RATIONALE: Electrical conductor selection depends on electrical and installation
characteristics such as ampacity and termination limitations, not vehicle paint specifications.
9. A customer reports that charging repeatedly stops after several minutes. The EVSE
displays an overtemperature indication. What should the technician investigate first?
A. Vehicle windshield tint
B. Thermal conditions at the EVSE and electrical connections
C. Radio frequency of the vehicle
D. Tire tread pattern
RATIONALE: An overtemperature indication warrants investigation of heat-producing
conditions such as excessive load, poor connections, inadequate ventilation, or equipment
temperature limits.
10. What is the principal function of an overcurrent protective device in an EV charging
circuit?
A. Improve battery chemistry
B. Protect conductors and equipment from excessive current
C. Increase charging speed automatically
D. Determine the vehicle's range
RATIONALE: Overcurrent protection limits the effects of excessive current and helps protect
conductors and connected equipment from damage.
11. A facility manager proposes connecting several EV chargers to an existing panel
without reviewing the panel's available capacity. What is the most appropriate response?
A. Install the chargers immediately
B. Determine the existing and proposed load before proceeding
C. Assume EV charging has no impact on demand
D. Remove the panel grounding conductor
RATIONALE: EVSE additions can significantly increase electrical demand. Load evaluation is
necessary before determining whether the existing distribution equipment can accommodate
them.
12. Which charging level commonly uses a dedicated higher-voltage AC supply for
residential and commercial charging applications?
A. Level 2
B. Level 1 USB charging
C. 12-volt accessory charging
D. Battery trickle maintenance only
RATIONALE: Level 2 charging commonly uses a dedicated AC circuit at a higher voltage than
typical Level 1 equipment and is widely used for residential and commercial EV charging.

13. What is the primary safety concern when inspecting a damaged EV charging
connector?
A. Connector appearance only
B. Potential electrical shock, arcing, overheating, or equipment damage
C. Vehicle resale value
D. Battery color
RATIONALE: Damaged connectors can expose energized parts, create poor electrical contact,
and produce heat or arcing, creating serious safety hazards.
14. Before servicing EVSE, what should be verified before a worker contacts electrical
conductors?
A. The vehicle's exterior has been washed
B. The equipment is properly de-energized and the absence of voltage is verified
C. The charging cable is coiled
D. The customer's account is active
RATIONALE: Safe electrical work requires appropriate isolation and verification rather than
relying solely on switches, displays, or assumptions about equipment status.
15. A charging station is installed outdoors. Which environmental consideration is
particularly important?
A. Exposure to moisture and weather
B. Vehicle seat material
C. Interior cabin lighting
D. Dashboard design
RATIONALE: Outdoor EVSE installations must account for environmental exposure and use
equipment and installation methods appropriate for the location.
16. What does EVSE stand for?
A. Electric Vehicle Supply Equipment
B. Electrical Voltage Safety Element
C. Electric Voltage Service Enclosure
D. Energy Vehicle Storage Equipment
RATIONALE: EVSE is the standard term for equipment that supplies electrical energy to an
electric vehicle and performs associated control and safety functions.
17. A charger is rated for a particular maximum current, but the vehicle requests less
current. What normally determines the actual charging current?
A. The EVSE and vehicle charging-control interaction
B. The vehicle's windshield size
C. The building's lighting schedule alone
D. The circuit breaker color
