1. During inspection of a Level 2 AC electric vehicle supply
equipment (EVSE) installation, the inspector finds a 208/240-volt
branch circuit supplying a hardwired EVSE. Which requirement is
most important when evaluating the branch-circuit ampacity?
A. The circuit only needs to accommodate the EVSE's average operating
current
B. The circuit must be sized based on the EVSE nameplate rating and
applicable continuous-load requirements
C. The circuit may be sized at 80% of the EVSE nameplate rating
D. The circuit rating is determined solely by the vehicle's battery
capacity
Answer: B.
Rationale: EV charging is generally treated as a continuous load for
circuit-sizing purposes. The inspector should verify the EVSE
nameplate rating, conductor ampacity, overcurrent protection, and
applicable code requirements rather than sizing the circuit according
to average or anticipated vehicle charging current.
2. An EV charging station is rated at 40 amperes continuous output.
Assuming the applicable installation rules require the branch circuit
1
,to be sized at 125% of the continuous load, what minimum branch-
circuit ampacity is required?
A. 40 A
B. 45 A
C. 50 A
D. 60 A
Answer: C. 50 A.
Rationale: A 40-ampere continuous load multiplied by 125% equals 50
amperes. The inspector should then verify that the conductors,
overcurrent protective device, disconnecting means, terminals, and
equipment are appropriately rated for the installation.
3. An inspector discovers that an EVSE nameplate specifies 48
amperes maximum continuous charging current, while the
installation uses a 50-ampere circuit breaker. What is the primary
concern?
A. The breaker is always acceptable because 48 A is below 50 A
B. The circuit may be undersized because continuous loading must be
considered
C. The breaker should be replaced with a 40-A breaker
D. The EVSE must be connected to a 100-A circuit
Answer: B. The circuit may be undersized because continuous
loading must be considered.
Rationale: If the EVSE draws 48 amperes continuously, applying the
125% continuous-load factor produces 60 amperes. A 50-ampere
branch circuit generally would therefore be insufficient unless a
specific applicable exception or equipment listing permits otherwise.

,4. During an inspection, the EVSE is installed outdoors. Which
condition should receive particular attention?
A. Whether the EVSE is rated for the environmental conditions of the
location
B. Whether the vehicle is manufactured domestically
C. Whether the charging cable is exactly 10 feet long
D. Whether the vehicle has a lithium-ion battery
Answer: A. Whether the EVSE is rated for the environmental
conditions of the location.
Rationale: Outdoor EVSE installations are exposed to rain, moisture,
temperature changes, sunlight, physical impact, and potentially
corrosive conditions. The inspector should verify that the equipment is
appropriately listed/labeled and suitable for the environment and
installation location.
5. Which component primarily provides overcurrent protection for
an EV charging branch circuit?
A. Pilot circuit
B. Branch-circuit overcurrent protective device
C. Vehicle traction battery
D. Charging connector latch
Answer: B. Branch-circuit overcurrent protective device.
Rationale: The branch-circuit overcurrent protective device protects
conductors and equipment from excessive current caused by overloads
and faults. It must be properly sized and coordinated with the EVSE
and conductor ampacity.
3
, 6. An EVSE is installed in a parking area where vehicles can strike
equipment. What should an inspector evaluate?
A. Only the color of the EVSE enclosure
B. Physical protection and suitability of the installation against vehicular
damage
C. The vehicle manufacturer's recommended tire pressure
D. Whether the charging connector is metallic
Answer: B. Physical protection and suitability of the installation
against vehicular damage.
Rationale: EVSE located in parking areas may be exposed to impact
from vehicles. The inspector should evaluate bollards, wheel stops,
equipment placement, mounting strength, guard protection, and other
measures required by the applicable code and approved design.
7. Which conductor is primarily responsible for providing a low-
impedance fault-current path from exposed non-current-carrying
metal parts back to the source?
A. Grounded conductor
B. Equipment grounding conductor
C. Pilot conductor
D. Communication conductor
Answer: B. Equipment grounding conductor.
Rationale: The equipment grounding conductor provides a fault-
current path intended to facilitate operation of the overcurrent
protective device when a line-to-ground fault occurs. Proper bonding
and grounding are essential to EVSE safety.
