CORD & CONNECTOR • SAFE USE
Inspect before use.
Stop when damage appears.
A quick visual check can identify conditions that belong with qualified service—not repeated charging attempts.
The charging cord and vehicle connector are handled more often than most parts of a home electrical installation. A visual check does not replace professional testing, but it can identify obvious damage that should stop a charging attempt.
Look before plugging in
Check for cuts, crushed sections, exposed conductors, bent or damaged contact areas, missing parts, contamination and signs of overheating. Inspect the connector and vehicle inlet in good light without inserting tools or touching electrical contacts.
Heat, odor and discoloration matter.
Stop charging if the cord, connector, receptacle or equipment shows unusual heat, melting, burning odor or discoloration. Do not keep resetting the circuit to test it.
Keep strain off the cable
Store the cable so its weight is supported and the connector is protected from impact. Do not drive over the cord, pinch it under a door or use an extension cord unless the vehicle and charging-equipment manufacturers expressly provide an approved arrangement.
Separate cleaning from repair
Follow the manufacturer’s instructions for exterior cleaning and keep liquid away from openings. Do not sand contacts, dismantle connectors or tape over electrical damage. A damaged assembly may require manufacturer service or replacement.
Document symptoms for service
Record indicator colors, app messages, the vehicle used, when the problem began and clear photos of visible damage. Do not include passwords, pairing codes or private location history.
Review our EV charger service planning and assessment process.
Cord and connector questions
Can I keep charging if the outer jacket is cut?
Stop using visibly damaged equipment and follow the manufacturer’s service instructions.
Should I spray cleaner into the connector?
No. Use only the product maker’s approved cleaning method.
Can a tripped breaker be reset repeatedly?
No. Repeated operation of protection requires diagnosis; do not bypass or repeatedly reset it.
What helps with service?
Provide the model, visible condition, indicator status, vehicle and safely taken photos.
