b. Where the local utility is unable to supply adequate power.

c. Where there is evidence suitable to the local enforcement agency substantiating that additional local utility infrastructure design requirements, directly related to the implementation of Section 5.106.5.3,

may adversely impact the construction cost of the project.

2. Areas of parking facilities served by parking lifts, including but not limited to, automated mechanical- access open parking garages as defined in the California Building Code; or parking facilities otherwise incapable of supporting electric vehicle charging. Areas of parking facilities served by parking lifts, provided the required percentage of EV Charger spaces are installed elsewhere.

full rated amperage at each EV capable space.

4. The service panel or subpanel circuit directory shall identify the reserved overcurrent protective device
space(s) as "EV CAPABLE". The raceway termination location shall be permanently and visibly marked as
"EV CAPABLE."

Note: A parking space served by electric vehicle supply equipment or designed as a future EV charging
space shall count as at least one standard automobile parking space only for the purpose of complying
with any applicable minimum parking space requirements established by an enforcement agency. See

2. Each EVCS shall reduce the number of required EV capable spaces by the same number.
3. At least one Level 2 EVSE shall be provided.

Separate and in addition to the requirements of

Section 5.106.5.3.1, fifteen (15) percent of the total number of parking spaces of Office and Retail Occupancies and ten (10) percent of the total number of parking spaces for all other nonresidential occupancies shall be EV capable spaces shall be provided with electric vehicle supply equipment (EVSE) to create EVCS in the number indicated in Table 5.106.5.3.1. Calculation of required EVCS shall be rounded up to the nearest whole number. The EVCS required by Table 5.106.5.3.1 by this section shall be provided with Level 2 EVSE or DCFC as permitted in Section 5.106.5.3.2.3. At least one minimum 6.6 kVA Level 2 EVSE shall be provided.

One EV charger with multiple connectors capable of charging multiple EVs simultaneously shall be permitted if the electrical load capacity required by Section 5.106.5.3.1 for each EV capable space is accumulatively supplied to the EV charger.

208/240V EV charging receptacles shall comply with one of the

following configurations:

1. For 20-ampere receptacles, NEMA 6-20R.

2. For 30-ampere receptacles, NEMA 14-30R.

3. For 50-ampere receptacles, NEMA 14-50R.

EV chargers shall be equipped with SAE J1772 with a maximum

output 240 Volts AC or SAE J3400 connectors.

When using level 2 SAE J3400 SAE connectors, supplied by a 480 V 3-phase service, at least 20 percent of the EV charger connectors shall be SAE J1772 with a maximum output 240 Volts AC.

reduce the minimum number of required EV capable spaces without EVSE in Table 5.106.5.3.1 required by Section 5.106.3.2.1 by one.

To allow for future upgrades to the electrical

conductors serving low power Level 2 charging receptacles, the listed raceway serving such receptacles shall be sized to allow the installation of a dedicated 208/240-volt 40-ampere branch circuit. Where no raceway is used, the conductors shall be sized to accommodate a 208/240-volt 40-ampere receptacle.

The power allocation

method, based on occupancy classification, may be used as an alternative to the requirements in Section 5.106.5.3.1, and Section 5.106.5.3.2 and associated Table 5.106.5.3.1. Use Table 5.106.5.3.6 the following factors to determine the total power in kVA required based on the total number of actual parking spaces.

A. Office and Retail Occupancies: The product of the factor of 0.99kVA/parking space times the total
number of parking spaces serving Office and/or Retail occupancies determines the total power in kVA for
EVSE charging infrastructure required.

B. For occupancies other than Office and Retail occupancies: The product of the factor 0.66 kVA/parking
space times the total number of parking spaces determines the power in kVA required for EVSE charging
infrastructure required.

Power allocation method shall include the following:

1. Use any kVA combination of EV capable spaces, low power Level 2, Level 2 or DCFC EVSEs.

2. At least one Level 2 EVSE shall be provided.

3. Any remainder power allocation kVA from Section 5.106.3.6 Item (1) shall be converted to one
additional low power Level 2 EVSE.
