Simply put charging equipment are electrical appliances and disconnecting requirements for this type of electrical equipment is already addressed in the National Electrical Code (NEC) and expanded on in the 2nd draft 2026 NEC.
E-stops are frequently suggested/advocated for with the primary argument being the need for consistency with gas stations, emergency response considerations for fuel dispensing stations bear no similarities with electrical fires at charging stations. Homologation with gas station disconnect requirements creates greater hazard for first responders and the general public who may attempt to intervene.
Activation of the emergency disconnect when responding to a fuel fed fire is accompanied with lessening fire activity, similar positive indicators do not exist for electrical equipment providing a false sense of security.
Activation of a similar disconnect at an EV charging station would not inform First Responders of what upstream proximally located equipment remains energized.
Physical load break disconnecting means, as required by the NEC, are the appropriate means to mitigate electrical hazards with charging equipment and ensure first responder safety.
Utilization of the disconnecting means at the switch gear is superior to an emergency stop button as this provides a physical break to create an open circuit with a clear indication of what equipment (site) is being placed into a de-energized state.
