Inspect EV Charger Cable and Connections

EV chargers run at high current for hours at a time, making loose connections and cable wear real fire hazards. Once a year, inspect: the charging cable for cuts, kinks, fraying, or cracked insulation — pay close attention to the ends near the plug and wall unit where bending is most frequent. Inspect the plug connector and pins for burn marks, carbon deposits, or bent pins — any charring means the unit needs professional service before next use. Check that the wall unit is mounted securely and that all mounting screws are tight. Turn off the circuit breaker and inspect the breaker itself — a EVSE circuit that has been tripping may have a breaker that needs replacement. Feel the wall unit and outlet plate after a full charging session — warm to the touch is acceptable, hot is a warning sign indicating a loose connection. Inspect the dedicated circuit breaker for signs of overheating or corrosion. If your charger is outdoors, check the weatherproof cover seals and ensure no water is entering the unit. For smart chargers, update firmware via the manufacturer's app. Review your charging logs for any failed sessions or unusual patterns.
