Correct answer: A - The vehicle's on-board charger limits the AC charging rate
An EVSE transmits a control pilot signal with a 40% duty cycle. What maximum current is being advertised to the vehicle?
Correct answer: B - 24 A
What is the PRIMARY reason a 20 mA trip threshold is permitted for the personnel protection system in listed Level 2 EVSE, when a Class A GFCI trips at 4-6 mA?
Correct answer: B - A ground-monitoring circuit continuously verifies EGC integrity
A technician measures a steady +9 V on the control pilot conductor at an EVSE with a vehicle plugged in. This indicates:

An electrical contractor is cited by an inspector for a branch circuit to an EVSE with a calculated voltage drop of 4%. The contractor disputes the citation. Which statement is correct?
Correct answer: D - The contractor is correct; the 3% figure appears in an Informational Note and is not enforceable
A 6 AWG THHN copper conductor (90°C rated, 75 A) supplies a hardwired 48 A EVSE. Ambient temperature is normal and there are no more than three current-carrying conductors in the raceway. The equipment terminations are rated 60°C. What ampacity governs this conductor?
Correct answer: A - 55 A, based on the 60°C column
A contractor wants to add EVSE to an existing commercial service without a load calculation of the entire facility. Twelve months of utility demand data is unavailable. Per NEC 220.87, what is the minimum acceptable alternative?
Correct answer: A - A 30-day recording at 15-minute intervals including the highest-demand season
