EVITP FINAL CERTIFICATION
EXAMINATION QUESTIONS AND
ANSWERS
1. According to NEC Article 625, EVSE equipment is considered what type of load for the
purpose of sizing branch circuits?
A. Non-continuous load
B. Intermittent load
C. Occasional load
D. Continuous load
Answer: D
Conceptual Explanation: Per NEC 625.41, the overcurrent protection and conductors for
electric vehicle charging equipment must be sized at 125% of the maximum load,
classifying it as a continuous load.
2. Which NEC Article covers the requirements for Electric Vehicle Power Transfer Systems?
A. Article 625
B. Article 430
C. Article 517
,D. Article 700
Answer: A
Conceptual Explanation: NEC Article 625 is the primary section governing the
installation, wiring, and equipment used for EV charging.
3. What is the maximum length allowed for an EV charging cable without a cable
management system?
A. 15 feet
B. 20 feet
C. 25 feet
D. 50 feet
Answer: C
Conceptual Explanation: NEC 625.17(C) states the maximum length of the output cable to
the EV shall be 25 feet unless equipped with a cable management system.
4. What is the nominal voltage for a Level 2 AC charging station in a typical commercial
setting with a 3-phase service?
A. 120V
B. 208V
C. 480V
D. 277V
, Answer: B
Conceptual Explanation: In commercial 3-phase systems, Level 2 charging usually utilizes
two phases of a 208Y/120V system.
5. A 40-amp Level 2 EVSE requires a circuit breaker sized at what minimum amperage?
A. 40A
B. 45A
C. 50A
D. 60A
Answer: C
Conceptual Explanation: 40A x 125% = 50A. A 50-amp OCPD is required for a 40-amp
continuous load.
6. The SAE J1772 connector is the standard for which type of charging in North America?
A. AC Level 1 and Level 2
B. DC Fast Charging only
C. Tesla Supercharging only
D. Wireless inductive charging
Answer: A
