EVITP CERTIFICATION EXAMINATION
PRACTICE TEST QUESTIONS AND
ANSWERS
1. According to NEC Article 625.41, how must the overcurrent protection for Electric Vehicle
Supply Equipment (EVSE) be sized?
A. At 100% of the maximum load
B. Based on the ambient temperature correction factor
C. At 80% of the maximum load
D. At 125% of the maximum load
Answer: D
Conceptual Explanation: NEC 625.41 states that EVSE is considered a continuous load;
therefore, the overcurrent protective device must be sized at no less than 125% of the
maximum load.
2. What is the maximum permissible length for an EV charge cable unless it is part of a cable
management system as per NEC 625.17(C)?
A. 25 feet (7.5 meters)
B. 20 feet (6.0 meters)
,C. 15 feet (4.5 meters)
D. 50 feet (15.0 meters)
Answer: A
Conceptual Explanation: NEC 625.17(C) specifies that the output cable to the electric
vehicle shall not exceed 25 feet in length unless equipped with a cable management system.
3. A Level 2 EVSE is rated for 40 Amps continuous output. What is the minimum circuit
breaker size and minimum wire ampacity required?
A. 40A breaker, 40A wire
B. 45A breaker, 45A wire
C. 50A breaker, 50A wire
D. 60A breaker, 60A wire
Answer: C
Conceptual Explanation: Calculation: 40A * 1.25 = 50A. A 50A breaker and conductors
rated for 50A are required to meet the 125% continuous load requirement.
4. Which NEC Article primarily governs the installation of Electric Vehicle Power Transfer
Systems?
A. Article 430
B. Article 250
C. Article 700
, D. Article 625
Answer: D
Conceptual Explanation: NEC Article 625 specifically covers the electrical conductors and
equipment external to an electric vehicle that connect the vehicle to a supply of electricity.
5. Under NEC 625.42, if an Automatic Load Management System (ALMS) is used, how is the
feeder or service load calculated?
A. Based on the maximum capacity of all EVSE units combined
B. At 50% of the total nameplate ratings
C. Based on the maximum set point of the ALMS
D. Based on the average usage over a 24-hour period
Answer: C
Conceptual Explanation: NEC 625.42 allows the maximum load to be limited by an ALMS.
The load calculation is based on the maximum capacity permitted by the ALMS, not the sum
of individual nameplates.
6. What type of Personnel Protection System is required for EV charging equipment by NEC
625.22?
A. Standard Class A GFCI
B. Arc-Fault Circuit Interrupter (AFCI)
C. Listed personnel protection system (CCID)
