LATEST EVITP EXAM FINAL PREP
QUESTIONS AND ANSWERS
1. According to NEC Article 625, EV charging loads are considered to be of what type when
calculating the circuit size?
A. Intermittent loads
B. Non-continuous loads
C. Demand-factor loads
D. Continuous loads
Answer: D
Conceptual Explanation: NEC 625.41 states that the overcurrent protection for the EVSE
shall be sized for 125% of the maximum load, because EV charging is defined as a
continuous load.
2. Which NEC article primarily governs the installation of Electric Vehicle Power Transfer
Systems?
A. Article 625
B. Article 430
C. Article 690
,D. Article 705
Answer: A
Conceptual Explanation: Article 625 covers the electrical conductors and equipment
connecting an electric vehicle to any source of electric current.
3. What is the maximum permissible length for a portable EVSE output cable without a cable
management system?
A. 15 feet
B. 20 feet
C. 50 feet
D. 25 feet
Answer: D
Conceptual Explanation: NEC 625.17(C) limits the overall length of the output cable to 25
feet unless equipped with a cable management system.
4. For a Level 2 EVSE rated at 48 Amps, what is the minimum required size for the branch
circuit overcurrent protection device (OCPD)?
A. 50 Amps
B. 80 Amps
C. 70 Amps
D. 60 Amps
, Answer: D
Conceptual Explanation: 48 Amps multiplied by 1.25 (125% for continuous load) equals
60 Amps.
5. Under NEC 625.42, what allows for a lower ampacity service to be used for EVSE
installations than the sum of the nameplate ratings?
A. Automatic Load Management Systems (ALMS)
B. Diversity factors
C. Demand Response
D. Peak-shaving batteries
Answer: A
Conceptual Explanation: NEC 625.42(B) permits the use of an Automatic Load
Management System (ALMS) to control the load on the service or feeder.
6. What signal is transmitted on the Control Pilot pin of a J1772 connector to indicate the
maximum available current to the vehicle?
A. DC Voltage Level
B. Digital Data Packet
C. Pulse Width Modulation (PWM) duty cycle
D. Audio Frequency Signal
Answer: C
