What is the first step when troubleshooting a non-functional EVSE that shows no power?
Answer: Check the circuit breaker and power supply
Verifying the circuit breaker and power supply status is the first diagnostic step for a non-functional EVSE.
Which diagnostic tool is commonly used to test the continuity of EVSE wiring?
Answer: Multimeter
A multimeter is the standard tool for checking continuity, voltage, and resistance in EVSE wiring.
How often should EVSE equipment undergo routine preventive maintenance inspections?
Answer: Annually
Annual preventive maintenance inspections help identify wear and potential issues before equipment failure occurs.
What does a ground fault in an EVSE typically indicate?
Answer: An unintended path of current to ground
A ground fault indicates current is flowing along an unintended path to ground, which is a safety hazard requiring immediate attention.
Which component in an EVSE is responsible for communicating charging status and current capacity to the vehicle?
Answer: The pilot circuit
The pilot circuit (Control Pilot) is the signal line that communicates charging state and current capacity between the EVSE and the vehicle.
What is the critical safety step before replacing a damaged EVSE connector?
Answer: De-energize and lock out the circuit
De-energizing and applying lockout/tagout procedures is mandatory before replacing any EVSE component to prevent electrical shock.
