<br />raceway termination point, receptacle or charger location, as applicable. The service panel and/ or subpanel shall
<br />have a 40-ampere minimum dedicated branch circuit, including branch circuit overcurrent protective device
<br />installed, or space(s) reserved to permit installation of a branch circuit overcurrent protective device.
<br />Exception: A raceway is not required if a minimum 40-ampere 208/240-volt dedicated EV branch circuit is
<br />installed in close proximity to the location or the proposed location of the EV space, at the time of original
<br />construction in accordance with the California Electrical Code.
<br />2.Multiple EV spaces required. Construction documents shall indicate the raceway termination point and the
<br />location of installed or future EV spaces, receptacles or EV chargers. Construction documents shall also provide
<br />information on amperage of installed or future receptacles or EVSE, raceway method(s), wiring schematics and
<br />electrical load calculations. Plan design shall be based upon a 40-ampere minimum branch circuit. Required
<br />raceways and related components that are planned to be installed underground, enclosed, inaccessible or in
<br />concealed areas and spaces shall be installed at the time of original construction.
<br />SECTION 4.501 GENERAL
<br />4.501.1 Scope

<br />4.106.4.2.4 Identification.
<br />The service panel or subpanel circuit directory shall identify the overcurrent protective device space(s) reserved for
<br />future EV charging purposes as “EV CAPABLE” in accordance with the California Electrical Code.
<br />4.106.4.2.5 Electric Vehicle Ready Space Signage.
<br />Electric vehicle ready spaces shall be identified by signage or pavement markings, in compliance with Caltrans
<br />Traffic Operations Policy Directive 13-01 (Zero Emission Vehicle Signs and Pavement Markings) or its
<br />successor(s).
<br />4.106.4.3 Electric vehicle charging for additions and alterations of parking facilities serving existing
<br />multifamily buildings.
<br />When new parking facilities are added, or electrical systems or lighting of existing parking facilities are added or
<br />altered and the work requires a building permit, ten (10) percent of the total number of parking spaces added or
<br />altered shall be electric vehicle charging spaces (EV spaces) capable of supporting future Level 2 EVSE.
<br />Notes:
<br />1.Construction documents are intended to demonstrate the project’s capability and capacity for facilitating future
<br />EV charging.
<br />2.There is no requirement for EV spaces to be constructed or available until EV chargers are installed for use.
