Question 1
What is the minimum NEC-required clearance for EVSE equipment per NEC 625.34?
A. 2 feet
B. 3 feet
C. 4 feet
D. 6 feet
ANSWER: B. 3 feet.
RATIONALE: NEC 625.34 mandates a minimum of 3 feet of clearance around EVSE
equipment to ensure safe access for installation, maintenance, and operation.
Question 2
What is the maximum voltage for a Level 2 EVSE per NEC 625.10?
A. 120V
B. 240V
C. 480V
D. 600V
ANSWER: B. 240V.
RATIONALE: NEC 625.10 defines Level 2 EVSE as operating at up to 240V nominal, which is
the standard for residential and many commercial AC charging applications.
,Question 3
What is the purpose of a load management system in EVSE installations?
A. To increase power usage
B. To balance electrical demand
C. To reduce installation costs
D. To extend cable length
ANSWER: B. To balance electrical demand.
RATIONALE: Load management systems prevent overloading of the electrical panel by
dynamically balancing power distribution between EVSE and other loads, ensuring safe and
efficient operation.
Question 4
What is the minimum conductor size for a 40-amp EVSE circuit per NEC 310.16?
A. #10 AWG
B. #8 AWG
C. #6 AWG
D. #4 AWG
ANSWER: B. #8 AWG.
RATIONALE: According to NEC 310.16, a 40-amp circuit requires a minimum conductor size
of #8 AWG copper, assuming 75°C insulation and standard temperature ratings.
Question 5
What is the maximum continuous load for a 50-amp circuit breaker per NEC 210.19(A)(1)?
A. 40 amps
B. 50 amps
C. 60 amps
D. 80 amps
,ANSWER: A. 40 amps.
RATIONALE: NEC requires that continuous loads be sized at 125% of the continuous load.
For a 50-amp breaker, the maximum continuous load is 50 ÷ 1.25 = 40 amps.
Question 6
What type of GFCI protection is required for EVSE outlets per NEC 210.8?
A. Class A GFCI (5 mA)
B. Class B GFCI (20 mA)
C. No GFCI required
D. Equipment ground fault protection only
ANSWER: A. Class A GFCI (5 mA).
RATIONALE: NEC 210.8 requires Class A GFCI protection (5 mA trip level) for all receptacles
used for EVSE charging, including those in garages and outdoor locations.
Question 7
What is the definition of an electric vehicle according to the EVITP curriculum?
A. Any vehicle powered by gasoline
B. Any vehicle that uses electricity stored in batteries for propulsion
C. Any hybrid vehicle
D. Any vehicle with an electric starter
ANSWER: B. Any vehicle that uses electricity stored in batteries for propulsion.
RATIONALE: The EVITP curriculum defines an electric vehicle (EV) as a vehicle that uses
electricity stored in batteries as the primary source of propulsion energy.
Question 8
What is the difference between a Level 1 and Level 2 EVSE?
, A. Level 1 uses 120V; Level 2 uses 240V
B. Level 1 uses 240V; Level 2 uses 480V
C. Level 1 is faster; Level 2 is slower
D. Level 1 is for commercial use; Level 2 is for residential
ANSWER: A. Level 1 uses 120V; Level 2 uses 240V.
RATIONALE: Level 1 EVSE operates on standard 120V outlets (providing 1.4-1.9 kW), while
Level 2 EVSE operates on 240V circuits (providing 3.3-19.2 kW), allowing faster charging.
Question 9
What is the charging power of a typical Level 2 EVSE?
A. 1.4-1.9 kW
B. 3.3-19.2 kW
C. 50-350 kW
D. 500 kW
ANSWER: B. 3.3-19.2 kW.
RATIONALE: Level 2 EVSE provides 3.3 to 19.2 kW of charging power, depending on the
amperage and voltage configuration, and is used in residential and commercial settings.
Question 10
What is a DC Fast Charger (DCFC)?
A. A charger that uses alternating current
B. A charger that converts AC to DC outside the vehicle
C. A Level 1 charger
D. A charger that uses only 120V
ANSWER: B. A charger that converts AC to DC outside the vehicle.
RATIONALE: DC Fast Chargers convert AC power to DC power within the charging station
and deliver high-power DC directly to the vehicle's battery, bypassing the onboard charger.
