Claim 16:
17. An electric vehicle supply equipment (EVSE) unit configured in an EV charging system, the EVSE unit, comprising:
input line-side terminals;
output load-side terminals;
a solid-state switch disposed between the input line-side terminals and output load-side terminals;
a controller,
wherein the controller and solid-state switch are configured to both control a maximum allowable charging current available to an associated EV charging station when a plug-in electric vehicle (PEV) is plugged into the EV charging station and provide circuit protection to the associated EV charging station and PEV; and
an air-gap disconnect unit having a closeable air gap connected in series with the solid-state switch, between the input line-side terminals and output load-side terminals, wherein the EVSE unit is configurable in three possible states and at any given time is configured in one of said three possible states:
an ON state during which the closeable air gap of the air gap disconnect unit is closed and the solid-state switch is ON;
a STANDBY state during which the closeable air gap of the air gap disconnect unit is closed and the solid-state switch is OFF; and
an OFF state during which the closeable air gap of the air gap disconnect unit is open and the solid-state switch is OFF.
