EVITP FINAL CERTIFICATION
PRACTICE EXAM QUESTIONS AND
ANSWERS
1. According to NEC Article 625, EVSE equipment is considered what type of load for the
purpose of sizing branch circuits and feeders?
A. Intermittent load
B. Non-continuous load
C. Continuous load
D. Variable demand load
Answer: C
Conceptual Explanation: NEC 625.41 requires EVSE to be considered a continuous load,
meaning the branch circuit and overcurrent protection must be sized at 125% of the
maximum load.
2. What is the maximum permissible length of the output cable for EVSE without a cable
management system according to NEC 625.17?
A. 25 feet
,B. 20 feet
C. 15 feet
D. 30 feet
Answer: A
Conceptual Explanation: NEC 625.17 limits the cable length to 25 feet unless the
equipment is provided with a cable management system.
3. Which NEC article covers the grounding and bonding requirements for EVSE systems?
A. Article 250
B. Article 430
C. Article 625
D. Article 700
Answer: A
Conceptual Explanation: While Article 625 covers EVSE-specific rules, Article 250 is the
primary reference for general grounding and bonding for all electrical systems.
4. What is the primary function of the ‘Pilot’ signal in the J1772 connector protocol?
A. To communicate the maximum current capacity of the EVSE to the vehicle
B. To provide high-voltage power to the battery
C. To identify the type of coolant used in the cable
, D. To handle the chassis grounding connection
Answer: A
Conceptual Explanation: The Pilot signal uses a Pulse Width Modulation (PWM) signal to
communicate the maximum available current to the EV’s onboard charger.
5. For an indoor installation of EVSE, what is the required minimum height for the coupling
means above the floor?
A. 18 inches
B. 12 inches
C. 24 inches
D. 48 inches
Answer: A
Conceptual Explanation: NEC 625.50 states that for indoor locations, the coupling means
shall be stored or located at a height of not less than 18 inches above the floor level.
6. What is the demand factor used for the first 150 kVA of a commercial EV charging feeder
load?
A. 125%
B. 100%
C. 80%
D. 50%
