B. 120V, 15A
C. 480V, 125A
D. 208V, 40A
Correct Answer: B. 120V, 15A
Rationale: Level 1 chargers use a standard 120V AC branch circuit, typically 15 amperes,
and provide approximately 1kW to 2kW of power output. These are commonly used in
residential settings for overnight charging .

A. Level 1
B. Level 2
C. Level 3
D. Level 4
Correct Answer: C. Level 3
Rationale: Level 3 chargers, also known as direct current fast chargers (DCFC), typically
use 3-phase 480V or 208V AC power input converted to 200V to 1,000V DC output,
delivering power directly to the battery .

a Level 2 charger?
A. Less than 1 hour
B. 2-4 hours
C. Approximately 10 hours
D. More than 40 hours
Correct Answer: C. Approximately 10 hours
Rationale: With a higher power output (7kW to 19kW), Level 2 chargers provide improved
charge times compared to Level 1 chargers—approximately 10 hours to fully charge a
60kWh battery from empty .

regulation
, Rationale: The control pilot enables handshake communication between the EVSE and the
vehicle to ensure safe operation and allows charging current regulation based on vehicle
needs .
SECTION 2: NEC ARTICLE 625 COMPLIANCE AND CODE REQUIREMENTS
11. Which NEC article specifically governs electric vehicle supply equipment (EVSE)?
A. Article 210
B. Article 310
C. Article 625
D. Article 700
Correct Answer: C. Article 625
Rationale: NEC Article 625 covers conductors, grounding, disconnects, and all
requirements specifically for electric vehicle supply equipment .
12. According to NEC 625.41, how must conductors for EVSE be sized?
A. 80% of the load rating
B. 100% of the load rating
C. 125% of the maximum load
D. 150% of the load rating
Correct Answer: C. 125% of the maximum load
Rationale: NEC 625.41 requires that EVSE conductors be considered a continuous load
and sized at 125% of the maximum load to account for continuous duty operation .
