I shared this with our local Tesla group:
- tight loops - this puts extra stress on the conductors. Called 'work hardening', copper can become brittle, break, and the cable needs to be replaced.
- lying on ground - in a wind, the rough surface wears the outside insulation leading to early cable failure. It is also a trip hazard for anyone walking by.
- loop on loop - this adds weight to the cable putting stress to pull the cable from the charger. Once separated, repair is expensive and time consuming.
