For cord-connected EVSEs without a cable management system, the maximum usable length of the cable is which value?

• A. 7.5 feet
• B. 12 feet
• C. 25 feet
• D. 30 feet

Answer: (C)

The main idea is that the supply cord for a cord-connected EVSE is restricted to a practical length to keep the electrical and thermal behavior within safe, listed limits. For cord-connected units without a cable management system, that limit is 25 feet. Keeping the cord to this length helps minimize voltage drop at the vehicle inlet and avoids excessive heating or wear in the flexible cord at the rated charging current. If more reach is needed, you’d switch to a different installation method—such as a hardwired, permanently installed EVSE or using a management system with a longer cord that remains within its listed/approved parameters.
