Attachment 1 Exhibit B i. Conduit that links a listed electrical panel with sufficient capacity to a junction box or receptacle located within three(3)feet of the parking space. ii. The conduit shall be designed to accommodate at least 8.3 kVa(208/240 volt,40-ampere)per parking space.Conduit shall have a minimum nominal trade size of 1 inch inside diameter and may be sized for multiple circuits as allowed by the California Electrical Code. Conduit shall be installed at a minimum in spaces that will be inaccessible after construction,either trenched underground or where penetrations to walls,floors, or other partitions would otherwise be required for future installation of branch circuits,and such additional elements deemed necessary by the Building Official. Construction documents shall indicate future completion of conduit from the panel to the parking space,via the installed inaccessible conduit. iii. The electrical panel shall reserve a space for a 40-ampere overcurrent protective device space(s) for EV charging, labeled in the panel directory as"EV CAPABLE." iv. Electrical load calculations shall demonstrate that the electrical panel service capacity and electrical system, including any on-site distribution transformer(s),have sufficient capacity to simultaneously charge all EVs at all required EV spaces at a minimum of 40 amperes. v. The parking space shall contain signage with at least a 12"font adjacent to the parking space indicating the space is EV Capable. LEVEL 1 EV READY.A parking space that is served by a complete electric circuit with the following requirements: i. A minimum of 2.2 kVa(110/120 volt,20-ampere)capacity wiring. ii. A receptacle labeled"Electric Vehicle Outlet"or electric vehicle supply equipment located within three(3)feet of the parking space. If EVSE is provided the minimum capacity of the EVSE shall be 16-ampere. iii. Conduit oversized to accommodate future Level 2 EV Ready(208/240 volt,40-ampere)at each parking space. LEVEL 2 EV READY.A parking space that is served by a complete electric circuit with the following requirements: i. A minimum of 8.3 kVa(208/240 volt,40-ampere)capacity wiring. ii. A receptacle labeled"Electric Vehicle Outlet"or electric vehicle supply equipment located within three(3)feet of the parking space.If EVSE is provided the minimum capacity of the EVSE shall be 30-ampere. LOW POWER LEVEL 2 EV READY.A parking space that is served by a complete electric circuit with the following requirements: i. A minimum of 4.1 kVA(208/240 Volt, 20-ampere)capacity wiring. ii. A receptacle labeled"Electric Vehicle Outlet"or electric vehicle supply equipment located within three(3)feet of the parking space. If EVSE is provided the minimum capacity of the EVSE shall be 16-ampere. iii. Conduit oversized to accommodate future Level 2 EV Ready(208/240 volt,40-ampere)at each parking space. 20.26.060 Section 301.1.1 amended—Additions and alterations. Section 301.1.1 is amended to read as follows: 301.1.1 Additions and alterations. [HCD] The mandatory provisions of Chapter 4 shall be applied to additions or alterations of existing residential buildings where the addition or alteration increases the building's conditioned area,volume,or size. The requirements shall apply only to and/or within the specific area of the addition or alteration. (No change to existing California amendment.) Page 39 of 60
