sufficient capacity to provide at least 110/120 volts and 20 amperes
to the parking space. Raceways linking the electrical panel and parking
space only need to be installed in spaces that will be inaccessible
in the future, either trenched underground or where penetrations to
walls, floors, or other partitions would otherwise be required for
future installation of branch circuits. Raceways must be at least
1″ in diameter and may be sized for multiple circuits as allowed
by the California Electrical Code. The panel circuit directory shall
identify the overcurrent protective device space(s) reserved for EV
charging as "EV CAPABLE." Construction documents shall indicate future
completion of raceway from the panel to the parking space, via the
installed inaccessible raceways.
A parking space served by a complete electric circuit with
a minimum of 110/120 volt, 20-ampere capacity including electrical
panel capacity, overprotection device, a minimum 1″ diameter
raceway that may include multiple circuits as allowed by the California
Electrical Code, wiring, and either a) a receptacle labeled "Electric
Vehicle Outlet" with at least a ½″ font adjacent to
the parking space, or b) electric vehicle supply equipment (EVSE).
A parking space served by a complete electric circuit with
208/240 volt, 40-ampere capacity including electrical panel capacity,
overprotection device, a minimum 1″ diameter raceway that may
include multiple circuits as allowed by the California Electrical
Code, wiring, and either a) a receptacle labeled "Electric Vehicle
Outlet" with at least a ½″ font adjacent to the parking
space, or b) electric vehicle supply equipment (EVSE) with a minimum
output of 30 amperes.
A parking space served by a complete electric circuit with
at least a 208/240 volt, 40-ampere capacity including electrical panel
capacity, overprotection device, a minimum 1″ diameter raceway

be used to satisfy a Level 2 EV Ready Space requirement.
A parking space that includes installation of electric vehicle
supply equipment (EVSE) with a minimum capacity of 40 amperes connected
to a circuit serving a Level 3 EV Ready Space. EVCS installation may
be used to satisfy a Level 3 EV Ready Space requirement. As applied
to this code, a Level 3 shall be SAE J1772 (IEC Type 1) or alternative
approved by the chief building official.
(ALMS) A control system which allows multiple EV chargers
or EV-Ready electric vehicle outlets to share a circuit or panel and
