What is the required action of EVSE equipment if strain is placed on the charging cable?

The required action of Electric Vehicle Supply Equipment (EVSE) when strain is placed on the charging cable is to deenergize. This safety feature is critical to prevent accidents or damage. If the cable is under strain, it could indicate a potential issue that may lead to electrical arcing, cable damage, or even a serious safety hazard.

Deenergizing the system allows the flow of electricity to stop, protecting both the user and the equipment. This action ensures that if the charging cable is compromised due to the strain, it does not conduct electricity, reducing the risk of electric shock or fire hazards. In contrast, other options like activating or isolating do not directly address the immediate danger posed by a strained cable. Restricting the cable might imply a mechanical limitation without addressing the hazardous electrical conditions that can arise from the strain, making deenergizing the most effective and safe response.
