SECTION 1: NEC ARTICLE 625 FUNDAMENTALS (Questions 1-35)
Question 1 (Multiple choice)
According to NEC Article 625, the conductors supplying Electric Vehicle Supply
Equipment (EVSE) must have an ampacity of at least what percentage of the
EVSE's maximum load?
A) 100%
B) 115%
C) 125%
D) 150%
,Answer: C (NEC 625.41 states that EVSE shall be considered a continuous load
for branch circuit and feeder calculations. Per the definition of a continuous load
(NEC Article 100) and requirements in 210.19(A)(1)(a), conductors must be sized
at 125% of the continuous load. This is one of the most fundamental and frequently
tested rules in EVITP.)
Question 2 (Multiple choice)
When installing a Level 2 EVSE on a dedicated 40-amp circuit in a new dwelling
unit garage, what is the MINIMUM size THHN copper conductor required in the
raceway?
A) 8 AWG
B) 6 AWG
C) 4 AWG
D) 10 AWG
Answer: A (A 40-amp circuit requires conductors sized for 125% of the load: 40A
× 1.25 = 50A. Referring to NEC Table 310.16, an 8 AWG copper conductor at
75°C (common termination rating) has an ampacity of 50A. 10 AWG is only rated
for 35A, and 6 AWG (65A) would be larger than the minimum required.)
Question 3 (Multiple choice)
A commercial installation plans for ten (10) identical Level 2 EVSE units. Each
unit has a nameplate rating of 32 amps at 208V. Using the demand factors in Table
625.42, what is the calculated load for the feeder supplying all ten units?
A) 256 amps
B) 320 amps
C) 200 amps
D) 192 amps
Answer: D (First, the continuous load per unit is 32A × 1.25 = 40A. For 10 units,
the total connected load is 10 × 40A = 400A. Now apply the demand factor from
NEC Table 625.42. For 10 units, the demand factor is 48%. Therefore, 400A ×
0.48 = 192A. This tests your ability to apply both the continuous load rule AND
the commercial demand factors correctly.)
,Question 4 (Multiple choice)
Which of the following is NOT a required characteristic of an EV coupler
(connector) as specified in NEC 625.13?
A) It must be listed for the purpose.
B) It must be polarized.
C) It must have a "dead-front" design (no exposed pins when disconnected).
D) It must be capable of being locked in the connected position.
Answer: D (NEC 625.13(A) requires couplers to be listed, polarized, and have a
dead-front design. While some connectors may have a locking feature, it is not a
code-mandated characteristic. This is a classic "EXCEPT" question—read
carefully. Locking the disconnecting means is required, not necessarily the
connector itself.)
Question 5 (Multiple choice)
Under NEC 2023, an individual branch circuit is required for EVSE outlets greater
than:
A) 15 amperes
B) 16 amperes
C) 20 amperes
D) 30 amperes
Answer: B (NEC 625.40 was revised in the 2023 code to require an individual
branch circuit only for EVSE outlets greater than 16 amperes or outlets greater
than 120 volts. Requiring an individual branch circuit for a 15A or 20A receptacle
outlet to serve a Level 1 charger was considered excessive.)
Question 6 (Multiple choice)
According to NEC Article 100, EVSE is defined as:
A) The electric vehicle itself
B) The charging cable only
C) The conductors, including the power block, pedestal, charging cables,
, wiring, and any associated equipment
D) The utility meter
Answer: C (As defined in NEC 2023 Art. 100, EVSE includes the power block,
pedestal, charging cables, wiring, and any associated equipment necessary for the
transfer of energy between the premises wiring and the electric vehicle.)
Question 7 (Multiple choice)
What is the maximum ampere rating for a Level 1 EVSE?
A) 12 amps
B) 16 amps
C) 20 amps
D) 30 amps
Answer: B (Level 1 EVSE operates on a standard 120-volt circuit and is limited to
16 amperes maximum. Level 2 EVSE operates on 208-240 volts and can range
from 16 to 80 amperes.)
Question 8 (Multiple choice)
NEC 625.42 requires that EV charging loads be considered:
A) Intermittent loads
B) Continuous loads
C) Non-continuous loads
D) Standby loads
Answer: B (NEC 625.42 requires that EV charging is a continuous load and
therefore 80% of the branch circuit rating shall not be exceeded. This is why
conductors must be sized at 125% of the load.)
Question 9 (Multiple choice)
Which of the following is a key change in the 2023 NEC regarding EVSE?
A) EVSE is no longer considered a continuous load
B) GFCI protection is now required for all cord-and-plug connected EVSE
