What error condition typically indicates a communication failure between the EVSE and the vehicle?
Answer: A Control Pilot (CP) signal fault
A Control Pilot (CP) signal fault indicates a communication error in the pilot circuit between the EVSE and electric vehicle.
Which type of meter should be used to measure insulation resistance in EVSE wiring?
Answer: Megohmmeter
A megohmmeter (megger) applies high voltage to measure insulation resistance and detect wiring degradation in EVSE circuits.
What does a consistently tripping GFCI breaker in an EVSE installation most likely indicate?
Answer: A ground fault or leakage current in the circuit
A repeatedly tripping GFCI indicates the presence of ground fault current or leakage current exceeding the safe threshold.
What is the appropriate response when an EVSE displays an over-temperature fault?
Answer: Shut down charging and investigate ventilation
An over-temperature fault requires immediate charging shutdown and investigation of cooling and ventilation to prevent equipment damage or fire.
Which maintenance task helps prevent connector degradation at EVSE installations?
Answer: Cleaning contacts and inspecting for wear regularly
Regular cleaning of electrical contacts and visual inspection for wear prevents connection degradation and ensures reliable charging performance.
What is the purpose of the proximity pilot (PP) circuit in a Level 2 EVSE connector?
Answer: To detect when the connector is properly inserted into the vehicle
The proximity pilot circuit detects when the connector is properly seated in the vehicle inlet, enabling the charging process to begin safely.
