CERTIFICATION EXAM
1. According to NEC Article 625.41, how must the overcurrent protection for an Electric
Vehicle Supply Equipment (EVSE) circuit be calculated?
A. At 100% of the maximum load of the EVSE
B. At 150% of the maximum load of the EVSE
C. At 80% of the maximum load of the EVSE
D. At 125% of the maximum load of the EVSE
Answer: D
Conceptual Explanation: EV charging is considered a continuous load by the NEC, thus the
branch circuit and overcurrent protection must be sized at 125% of the rated load.
2. Which NEC section requires a disconnecting means for EVSE rated more than 60 amperes
or more than 150 volts to ground?
A. NEC 210.8
,B. NEC 625.17
C. NEC 625.50
D. NEC 625.43
Answer: D
Conceptual Explanation: NEC 625.43 specifies that a disconnecting means is required for
EVSE rated more than 60A or more than 150V to ground, and it must be lockable in the
open position.
3. In a commercial installation, what is the maximum height for an EVSE operable part
according to ADA accessibility guidelines?
A. 36 inches
B. 42 inches
C. 48 inches
D. 54 inches
Answer: C
Conceptual Explanation: ADA guidelines generally require operable parts to be no higher
than 48 inches above the finished floor to allow for a side reach.
4. When using an Automatic Load Management System (ALMS), the maximum electrical load
to the EVSE is controlled by:
A. The vehicle’s internal computer only
, B. A mechanical interlock switch
C. Manual adjustment by the user
D. A software-based controller that limits current based on available capacity
Answer: D
Conceptual Explanation: ALMS dynamically manages the power delivered to multiple
EVSEs to ensure the total load does not exceed the capacity of the service or feeder.
5. NEC 625.17(C) states that the maximum length of an EV cable, without a cable
management system, is:
A. 15 feet
B. 20 feet
C. 30 feet
D. 25 feet
Answer: D
Conceptual Explanation: The NEC limits the length of the EV cable to 25 feet unless it is
equipped with a cable management system.
6. A Level 2 EVSE typically operates at what voltage?
A. 120V AC
B. 480V AC
