EVSE shall have a(n) ? system for shock protection for personnel.

• A. approved
• B. listed
• C. marked
• D. labeled

Answer: (B)

Shock protection for personnel must come from equipment that has been independently tested and certified to meet safety standards. When an EVSE is listed, a recognized testing laboratory (such as UL) has evaluated the device and confirmed it meets required safety criteria for insulation, enclosure integrity, leakage currents, and protection against exposed live parts. This listing is your assurance that the system has undergone rigorous safety testing and is designed to minimize the risk of electric shock in normal and fault conditions. The other terms don’t carry the same guarantee. Approval may be jurisdictional or informal, not necessarily backed by third‑party testing. Marking or labeling identifies that some information or warnings exist on the device, but that alone doesn’t prove the device has been evaluated for safety performance. Listing, by contrast, is a formal safety certification tied to specific standards.
