EVITP FINAL EXAM 2026/2027
QUESTIONS AND ANSWERS
1. According to NEC Article 625.42, how must the rating of an Electric Vehicle Supply
Equipment (EVSE) be determined for the purpose of sizing branch circuit conductors and
overcurrent protection?
A. At 80% of the maximum load nameplate rating
B. As a non-continuous load at 100% of the maximum load
C. Based on the average usage over a 24-hour period
D. As a continuous load at 125% of the maximum load nameplate rating
Answer: D
Conceptual Explanation: NEC 625.42 specifies that EVSE shall be considered a continuous
load. Therefore, the branch circuit conductors and overcurrent protection must be sized at
125% of the equipment’s maximum load.
2. For an EVSE installation where the equipment is rated at more than 60 Amperes or more
than 150 Volts to ground, what is the NEC requirement for a disconnecting means?
A. A disconnect is only required if the unit is located outdoors
,B. No disconnect is required if the breaker is within 100 feet
C. A simple cord-and-plug connection is sufficient regardless of amperage
D. A disconnecting means must be provided and must be capable of being locked in the
open position
Answer: D
Conceptual Explanation: NEC 625.43 requires a disconnecting means for equipment rated
more than 60A or more than 150V to ground, which must be lockable in the open position.
3. What is the maximum permissible length for the output cable of an EVSE unit, unless
equipped with a cable management system, according to NEC 625.17(C)?
A. 15 feet (4.5 m)
B. 20 feet (6.0 m)
C. 25 feet (7.5 m)
D. 50 feet (15.0 m)
Answer: C
Conceptual Explanation: NEC 625.17(C) states that the output cable length shall not
exceed 25 feet unless the equipment is listed and marked for use with a cable management
system.
, 4. When installing an indoor EVSE, what is the minimum required height for the coupling
point above the floor level?
A. 12 inches
B. 36 inches
C. 24 inches
D. 18 inches
Answer: D
Conceptual Explanation: NEC 625.50 specifies that for indoor sites, the coupling point of
the EV connector must be stored at a height of not less than 18 inches above the floor level.
5. For an outdoor EVSE installation, what is the minimum required height for the coupling
point above the grade?
A. 18 inches
B. 48 inches
C. 36 inches
D. 24 inches
Answer: D
Conceptual Explanation: NEC 625.50 requires that for outdoor sites, the coupling means
must be stored at a height not less than 24 inches above the grade.
