EVITP FINAL EXAM 2026/2027
QUESTIONS AND ANSWERS
1. According to NEC 625.40, which of the following is required for each outlet installed for the
purpose of charging electric vehicles?
A. A multiwire branch circuit shared with other garage loads
B. A dedicated subpanel for every two charging stations
C. An individual branch circuit with no other outlets
D. A shared circuit provided the load does not exceed 80% capacity
Answer: C
Conceptual Explanation: NEC 625.40 requires that each outlet installed for EV charging
be supplied by an individual branch circuit with no other outlets.
2. When calculating the load for an EVSE branch circuit, the equipment must be considered a:
A. Continuous load at 125% of the rating
B. Intermittent load
C. Non-continuous load
,D. Demand-adjusted load
Answer: A
Conceptual Explanation: Per NEC 625.41, EVSE is considered a continuous load, meaning
the branch circuit and overcurrent protection must be sized at 125% of the maximum load.
3. The maximum length of the output cable for a charging station, unless equipped with a
cable management system, is:
A. 15 feet (4.5m)
B. 20 feet (6.0m)
C. 25 feet (7.5m)
D. 50 feet (15m)
Answer: C
Conceptual Explanation: NEC 625.17(C) limits the length of the output cable to 25 feet
unless a cable management system is utilized.
4. Which standard was recently adopted as SAE J3400 for North American EV charging?
A. CCS Type 1
B. CHAdeMO
C. CCS Type 2
D. NACS (North American Charging Standard)
, Answer: D
Conceptual Explanation: SAE J3400 is the official designation for the North American
Charging Standard (NACS), facilitating its use across different manufacturers.
5. NEC 625.42(B) allows for ‘Energy Management Systems’ (EMS) to control EVSE loads. What
is the primary requirement for the maximum load calculation?
A. The load must be calculated based on the maximum rated current of the EVSE.
B. The maximum load is determined by the EMS setting, provided it is marked on the
equipment.
C. The load is calculated at 50% of the EVSE nameplate rating.
D. EMS cannot be used to reduce the size of the service conductor.
Answer: B
Conceptual Explanation: NEC 625.42 allows the maximum capacity to be determined by
an EMS, which can help in sizing service and feeder conductors based on the system’s
control capabilities.
6. For an EVSE rated at 48 Amps, what is the minimum required size for the overcurrent
protection device (OCPD)?
A. 48 Amps
B. 50 Amps
C. 60 Amps
