Electric vehicle (EV) charging and power-allocation requirements and tables

Q: How do I know whether to use the EV capable‑space route or the power allocation method?

You may choose either route where allowed. Use § 5.106.5.3.1 (raceway + reserved panel capacity + Table 5.106.5.3.1) for the EV capable‑space approach, or the power allocation method in § 5.106.5.3.6 and Table 5.106.5.3.6 to size total kVA for the whole parking area. Confirm local enforcing-agency acceptance.

Q: What minimum circuit provisioning should I show on electrical plans for each EV capable space?

Show a reserved 208/240 V, 40 A branch circuit (panel space and capacity) and a 1‑inch raceway from panel to near the parking space; label reserved breaker space and raceway termination “EV CAPABLE.” § 5.106.5.3.1 .

Q: Can I credit DC fast chargers (DCFC) against the number of required EV capable spaces?

Yes — each installed DCFC permits a reduction of five required EV capable spaces and reduces required electrical load capacity proportionally; document the trade and load calculations per § 5.106.5.3.2.3 .

Q: If I use SAE J3400 connectors for Level 2, is that fully allowed?

SAE J3400 is allowed when supplied from 480 V 3‑phase, but at least 20% of EV charger connectors must be SAE J1772 (240 V AC) . § 5.106.5.3.2.2 .

Q: Does installing an ALMS change the per‑space electrical capacity I must reserve?

Yes — when an Automatic Load Management System (ALMS) is used, the required electrical load capacity specified for an EVCS may be reduced ; each ALMS‑controlled EVSE must still deliver 30 A when charging a single vehicle and at least 3.3 kW when charging multiple vehicles simultaneously. § 5.106.5.3.3 .

Q: Where can I find the numeric kVA table for the power‑allocation method?

See Table 5.106.5.3.6 and § 5.106.5.3.6 for the required total kVA by parking count (examples: 101–150 = 165 kVA ). The table and its footnotes specify kVA per Level 2 (6.6 kVA) and maximum percent allocations.

CALGreen requires new nonresidential projects to provide EV‑ready infrastructure (raceway, reserved 208/240V 40A branch circuit capacity, markings) or meet EVCS counts, or use the power‑allocation method (Table 5.106.5.3.6) to size total kVA for parking; connectors, receptacles, DCFC credits and ALMS rules are specified in §§ 5.106.5.3.1, 5.106.5.3.2 and 5.106.5.3.6.

What the code requires — plain English

California requires new nonresidential construction to provide EV infrastructure either by installing EV capable spaces with reserved raceways and panel capacity, by installing EV charging stations (EVCS) per the receptacle/connector rules, or by using the power-allocation method (a total kVA requirement by parking count). These paths are set out in § 5.106.5.3.1, § 5.106.5.3.2, and § 5.106.5.3.6 of CALGreen; the power-allocation numbers are shown in Table 5.106.5.3.6.

Most important rule (plain English): Provide EV-ready infrastructure — meaning raceway, panel capacity and markings for future chargers, or meet the alternative EVCS/ power-allocation table thresholds — so parking areas can support EV charging now or in the future.

(First mention: § 5.106.5.3.1, § 5.106.5.3.2, § 5.106.5.3.6 are the controlling sections above.)

Requirements in detail

EV capable spaces — what must be installed (bolded first mentions)

Provide raceways sized not less than 1 inch (25 mm) diameter from a service panel/subpanel to a location near each EV capable parking space, terminating in a listed box or enclosure. A common raceway may serve multiple spaces. § 5.106.5.3.1.
Provide panel space and electrical load capacity for a dedicated 208/240 V, 40‑ampere minimum branch circuit for each EV capable space, with delivery of 30 amperes minimum to an installed EVSE at each EVCS. § 5.106.5.3.1.
The electrical system and any on-site distribution transformers must have sufficient capacity to supply full rated amperage at each EV capable space. § 5.106.5.3.1.
Mark reserved panel spaces and raceway termination locations visibly as “EV CAPABLE.” § 5.106.5.3.1.

Use Table 5.106.5.3.1 to determine how many EV capable spaces are required. (Note: the table itself is referenced in § 5.106.5.3.1 in the mandatory text; the exact Table 5.106.5.3.1 content was not located in the provided file snippets. A related voluntary appendix table appears at A5.106.5.3.1.) § 5.106.5.3.1.

Markdown summary table — EV capable space technical minimums

Decision item	Required value(s)	Code reference
Raceway minimum diameter	1 inch (25 mm)	§ 5.106.5.3.1
Reserved branch circuit at panel	208/240 V, 40 A minimum (space and load capacity reserved)	§ 5.106.5.3.1
Minimum delivered to installed EVSE	30 A	§ 5.106.5.3.1
System capacity requirement	Sufficient to supply full rated amperage at each EV space	§ 5.106.5.3.1
Identification/Marking	Panel directory: “EV CAPABLE”; raceway termination marked “EV CAPABLE”	§ 5.106.5.3.1

EV charging stations (EVCS) — receptacles, connectors, and trade-offs

Key items in § 5.106.5.3.2:

Receptacle configurations (208/240 V) permitted: NEMA 6‑20R for 20 A; NEMA 14‑30R for 30 A; NEMA 14‑50R for 50 A. § 5.106.5.3.2.1.
Connector types: SAE J1772 (max 240 V AC) or SAE J3400 connectors. If J3400 (Level 2 on 480 V 3‑phase) is used, at least 20% of connectors must be SAE J1772. § 5.106.5.3.2.2.
Installing a DC fast charger (DCFC) can reduce the number of required EV capable spaces by five and reduces required electrical load capacity proportionally. § 5.106.5.3.2.3.
Installing two low-power Level 2 receptacles may reduce required EV capable spaces by one; when low-power receptacles are used, raceway or conductor sizing must allow future upgrade to a 208/240 V 40 A branch circuit. § 5.106.5.3.2.4 and 5.106.5.3.2.4.1.

Decision item	Effect / minimum	Code reference
Allowed receptacles	NEMA 6‑20R, 14‑30R, 14‑50R	§ 5.106.5.3.2.1
Connectors	SAE J1772 or SAE J3400; if J3400 used, ≥20% must be J1772	§ 5.106.5.3.2.2
DCFC credit	Reduce EV capable spaces by 5; reduce panel load capacity proportionally	§ 5.106.5.3.2.3
Low-power Level 2 credit	2 low-power receptacles = reduce 1 EV capable space; raceway sized for future 40 A branch circuit	§ 5.106.5.3.2.4–.4.1

Power allocation method (total kVA by parking count)

The power-allocation method is an alternative compliance path in § 5.106.5.3.6: instead of meeting the EV capable-space counts, the project can provide a minimum total kVA (expressed as number of kVA required for the whole parking area) determined from Table 5.106.5.3.6. The power allocation may be used in any combination of EV capable spaces, low-power Level 2, Level 2, or DCFC EVSEs, but at least one Level 2 EVSE must be provided. § 5.106.5.3.6.

Reproduced (decision‑relevant rows) from Table 5.106.5.3.6 (values in kVA, based on 6.6 kVA per Level 2 EVSE):

Total number of parking spaces (P)	Minimum total kVA required
1–9	0 kVA
10–25	26.4 kVA
26–50	52.8 kVA
51–75	85.8 kVA
76–100	112.2 kVA
101–150	165 kVA
151–200	231 kVA
201 and over	Total required kVA = P × 0.20 × 6.6 (i.e., 20% of spaces × 6.6 kVA)

Notes in the table: Level 2 EVSE = 6.6 kVA minimum, at least one Level 2 EVSE required, maximum allowed kVA to be utilized for EV capable spaces is 75%, and for office & retail buildings the max allowed kVA for EV capable spaces is 25%. § 5.106.5.3.6 and Table 5.106.5.3.6.

Exceptions & special cases

The code provides a project-level exception if the local enforcing agency finds compliance infeasible due to no local utility power, utility unable to supply adequate power, or demonstrated adverse cost impact due to additional local utility infrastructure requirements. See § 5.106.5.3 exceptions.
Areas served by parking lifts or automated mechanical-access garages (or other parking that cannot physically support EV charging) may be exempt. § 5.106.5.3 exceptions.
For existing buildings undergoing qualifying alterations, the work must comply with either § 5.106.5.3 and Table 5.106.5.3.1 or § 5.106.5.3.6 and Table 5.106.5.3.6 for the number of spaces being added/altered; if existing EV capable infrastructure is available, EVCS must be installed at existing EV capable spaces before adding new EV capable spaces. § 5.106.5.4.1–.2.

Common mistakes

Relying on a raceway that is too small: the code requires ≥1 inch raceway or conductors sized to permit a 40 A branch circuit upgrade. Don’t assume a smaller conduit is acceptable. § 5.106.5.3.1 and § 5.106.5.3.2.4.1.
Forgetting to reserve panel space and label it “EV CAPABLE.” This is a required visual identification for reserved overcurrent device spaces. § 5.106.5.3.1.
Misapplying DCFC credit: installing a DCFC reduces the number of required EV capable spaces by five but you must also proportionally reduce panel/load capacity — don’t just remove spaces from the count without adjusting load calculations. § 5.106.5.3.2.3.
Using the power-allocation table but exceeding the allowed percentage of total kVA allocated to EV capable spaces (watch the 75% cap and the stricter 25% cap for office/retail). § 5.106.5.3.6 and Table 5.106.5.3.6 footnotes.

Worked example — apply the power-allocation method

Scenario: A commercial site has 120 parking spaces and chooses the power-allocation method under § 5.106.5.3.6.

Find the row for 101–150 spaces in Table 5.106.5.3.6: 165 kVA required. § 5.106.5.3.6.
Interpret: 165 kVA corresponds to a minimum number of Level 2 EVSE equivalents at 6.6 kVA each: 165 ÷ 6.6 = 25 Level 2 equivalents (so the site’s total power allocation equals ~25 Level 2 chargers). Table 5.106.5.3.6.
Design implications: at least one Level 2 EVSE must be installed on site. The project can allocate the 165 kVA in any mix of EV capable spaces, low-power Level 2, Level 2, or DCFC, subject to the maximum % of total kVA that can be assigned to EV capable spaces (see table footnotes: 75% general cap; 25% cap for office/retail). § 5.106.5.3.6.

Bottom line: For 120 spaces, design for 165 kVA of EV capacity and install at least one Level 2 charger; you may apportion that 165 kVA across charger types subject to the table footnotes. § 5.106.5.3.6.

Frequently asked questions

How do I know whether to use the EV capable‑space route or the power allocation method?

You may choose either route where allowed. Use § 5.106.5.3.1 (raceway + reserved panel capacity + Table 5.106.5.3.1) for the EV capable‑space approach, or the power allocation method in § 5.106.5.3.6 and Table 5.106.5.3.6 to size total kVA for the whole parking area. Confirm local enforcing-agency acceptance.

What minimum circuit provisioning should I show on electrical plans for each EV capable space?

Show a reserved 208/240 V, 40 A branch circuit (panel space and capacity) and a 1‑inch raceway from panel to near the parking space; label reserved breaker space and raceway termination “EV CAPABLE.” § 5.106.5.3.1.

Can I credit DC fast chargers (DCFC) against the number of required EV capable spaces?

Yes — each installed DCFC permits a reduction of five required EV capable spaces and reduces required electrical load capacity proportionally; document the trade and load calculations per § 5.106.5.3.2.3.

If I use SAE J3400 connectors for Level 2, is that fully allowed?

SAE J3400 is allowed when supplied from 480 V 3‑phase, but at least 20% of EV charger connectors must be SAE J1772 (240 V AC). § 5.106.5.3.2.2.

Does installing an ALMS change the per‑space electrical capacity I must reserve?

Yes — when an Automatic Load Management System (ALMS) is used, the required electrical load capacity specified for an EVCS may be reduced; each ALMS‑controlled EVSE must still deliver 30 A when charging a single vehicle and at least 3.3 kW when charging multiple vehicles simultaneously. § 5.106.5.3.3.

Where can I find the numeric kVA table for the power‑allocation method?

See Table 5.106.5.3.6 and § 5.106.5.3.6 for the required total kVA by parking count (examples: 101–150 = 165 kVA). The table and its footnotes specify kVA per Level 2 (6.6 kVA) and maximum percent allocations.
