exam conditions, and reinforce critical concepts through detailed rationales that
explain the reasoning behind each correct answer.
Q1: What does EVSE stand for?
A) Electric Vehicle Supply Equipment
B) Electronic Vehicle Safety Equipment
C) Electric Vehicle Service Engine
D) Energy Vehicle Supply Equipment
E) Electric Voltage Service Equipment
CORRECT ANSWER: A - Electric Vehicle Supply Equipment
Rationale: EVSE is the standardized acronym used throughout the electric vehicle
charging industry to refer to all equipment and components used to deliver
electrical energy to electric vehicles. This terminology is established by industry
standards and regulatory bodies including the National Electrical Code and UL
standards.
,Q2: Which level of EV charging is typically used for residential installations?
A) Level 0 charging
B) Level 1 charging
C) Level 2 charging
D) Level 3 charging
E) Level 4 charging
CORRECT ANSWER: C - Level 2 charging
Rationale: Level 2 charging at 240 volts is the standard for residential EVSE
installations, providing faster charging than Level 1 (120V) while being practical for
home use. Level 1 is standard household outlet charging, and Level 3 (DC fast
charging) is typically reserved for commercial installations due to infrastructure
requirements.
Q3: What is the maximum voltage for Level 1 charging?
A) 120 volts
B) 208 volts
C) 240 volts
D) 277 volts
E) 480 volts
CORRECT ANSWER: A - 120 volts
Rationale: Level 1 charging operates at standard household voltage of 120 volts,
single phase. This is the minimum charging standard and is the slowest method of
charging, typically providing 2-5 miles of range per hour of charging.
Q4: Level 2 charging typically operates at which voltage?
A) 120 volts single phase
,B) 208 volts single phase
C) 240 volts single phase
D) 277 volts three phase
E) 480 volts three phase
CORRECT ANSWER: C - 240 volts single phase
Rationale: Level 2 charging in residential applications uses 240 volts single phase
power, which is standard in most North American homes. This provides significantly
faster charging than Level 1, with typical charging rates of 25-30 miles of range per
hour.
Q5: What does NFPA stand for?
A) National Fire Prevention Association
B) National Fire Protection Association
C) National Facility Protection Agency
D) National Federal Protection Authority
E) National Fuel and Power Administration
CORRECT ANSWER: B - National Fire Protection Association
Rationale: NFPA is the National Fire Protection Association, the organization
responsible for developing the National Electrical Code (NEC/NFPA 70), which
governs electrical installations including EVSE systems and safety requirements.
Q6: Which edition of the National Electrical Code is currently the standard for
most EVSE installations?
A) 2017 NEC
B) 2020 NEC
C) 2023 NEC
, D) 2025 NEC
E) 2026 NEC
CORRECT ANSWER: C - 2023 NEC
Rationale: The 2023 National Electrical Code is the most current standard adopted
by most jurisdictions as of 2026. Electrical codes are updated every three years, and
installers must comply with the version adopted by their local authority having
jurisdiction (AHJ).
Q7: What is the primary safety standard for EVSE equipment certification?
A) UL 100
B) UL 200
C) UL 2089
D) UL 2891
E) UL 3100
CORRECT ANSWER: C - UL 2089
Rationale: UL 2089 is the standard for Safety of Batteries for Use in Stationary,
Vehicle Auxiliary Power and Light Electric Power Applications. EVSE equipment must
be certified to appropriate UL standards to ensure safety and proper performance.
Q8: What is the minimum wire gauge required for a 30-ampere Level 2 EVSE
circuit?
A) 12 AWG copper
B) 10 AWG copper
C) 8 AWG copper
D) 6 AWG copper
E) 4 AWG copper
