Title 24 · California Energy Code
How do I confirm a device’s certification status to meet Part 6 installation limits?
In plain terms: you may only install a Part 6 product if the manufacturer has certified it. For appliances, check the Energy Commission’s certified appliance database; for other products, accept a manufacturer’s sworn declaration or one of the four Commission‑approved proofs listed in **§ 110.0**. Don’t substitute on‑site tests for the approved documentation unless the Energy Commission’s procedures allow it.
Last reviewed: July 6, 2026
What the code requires — 2-4 sentences
Part 6 only allows installation of manufactured systems, equipment, appliances, and building components when the manufacturer has certified the item and the item meets the applicable installation provisions. The certification must be either the Title 20 Energy Commission certification for appliances in the Appliance Efficiency Regulations or a manufacturer’s declaration executed under penalty of perjury (for devices outside Title 20 scope). See § 110.0 and § 110.1 for the controlling requirements.
You may only install a manufactured device subject to Part 6 if the manufacturer has certified it and you confirm that certification using one of the Commission‑approved proof methods set out in § 110.0.
Requirements in detail
Who must certify what
- Appliances within the scope of the Appliance Efficiency Regulations (Title 20 §1601) must be certified to the Energy Commission by the manufacturer pursuant to Title 20 §1606. § 110.1(a).
- All other systems, equipment, appliances and building components required by Part 6 or the Reference Appendices to be certified must have a manufacturer’s declaration under penalty of perjury stating the information is true and that required test procedures were used (if applicable). § 110.0(b)2.
What counts as acceptable proof the device is certified
The code limits confirmation of a device’s certification status to these four exclusive sources in § 110.0(b)3:
- A directory published or approved by the Energy Commission;
- A copy of the application for certification from the manufacturer and the letter of acceptance from Commission staff;
- Written confirmation from the publisher of a Commission‑approved directory that the device has been certified;
- A Commission‑approved label on the device.
Table — decision‑relevant dimensions and where to look in the code
| Decision dimension | What to check | Code Reference |
|---|---|---|
| Is it an appliance under Title 20 §1601? | If yes, require Energy Commission certification via the Title 20 database | § 110.1(a) |
| Manufacturer declaration required? | Non‑Title 20 items required by Part 6 need a declaration under penalty of perjury | § 110.0(b)2 |
| Acceptable verification methods | Directory, application + acceptance letter, publisher confirmation, or Commission label ONLY | § 110.0(b)3 |
| Where to find certified appliances | Energy Commission’s certified appliance database (www.energy.ca.gov/appliances/database/) or approved equivalents | § 110.1(b) |
| If no directory data exists | Use default mandatory efficiency levels or Commission‑approved procedures per Title 24 Part 1 when allowed | § 110.1(c) |
Verification sources — practical notes
- The preferred verification route for appliances is the Energy Commission database listed in § 110.1(b)(1) (the publicly accessible appliance database). If an equivalent federal or approved trade association directory exists, that is also acceptable under § 110.1(b)(2–3).
- For manufacturers’ declarations (non‑Title 20 items), confirm the declaration exists and that it affirms testing was performed using the test method in Part 6 (where applicable). See § 110.0(b)2(A–B).
Exceptions & special cases
- When data to verify conformance is not available in the approved directories, § 110.1(c) allows compliance to be shown by defaulting to the mandatory efficiency levels in Part 6 or by following procedures approved by the Energy Commission (Title 24, Part 1 Section 10‑109). This is a documented pathway — do not invent testing methods on site unless approved.
- Part 6 explicitly states it does not require the builder, designer, owner, operator, or enforcing agency to independently test certified devices to determine compliance with minimum specifications or efficiencies adopted by the Commission. Rely on the approved proof sources instead. § 110.0 note.
- Some device types (lighting controls, acceptance testing) have separate acceptance/certificate requirements elsewhere in Part 6 — where those acceptance certificates are required, follow the specific installation and acceptance procedures (see related provisions below).
Common mistakes
- Looking only at a manufacturer’s product sheet or sticker that is not a Commission‑approved label — the code accepts a Commission‑approved label, not an arbitrary manufacturer sticker. See § 110.0(b)3(D).
- Assuming an entry in a third‑party catalog equals Commission certification — only Commission‑approved directories, federal equivalent directories, or approved trade association directories count (per § 110.0(b)3 and § 110.1(b)).
- Requiring on‑site testing of a certified device as a substitute for the approved documentation — Part 6 says enforcing agencies are not required to test certified devices. § 110.0 note.
- Not confirming that a manufacturer’s declaration includes the statement that required test procedures were used (when applicable) — the perjury declaration must include that assertion where a test procedure applies. § 110.0(b)2.
Worked example — concrete scenario with numbers
Scenario: You are the enforcement inspector for a new small apartment building. The installer has provided a bank of 12 package rooftop heat‑pump water heaters. Each unit is an appliance covered by the Appliance Efficiency Regulations.
Step 1 — Is it a Title 20 appliance? Yes — the unit model appears to be covered under the Appliance Efficiency Regulations. Per § 110.1(a), the unit may only be installed if it fully complies with Section 1608(a) of the Appliance Efficiency Regulations.
Step 2 — Verify certification using the approved source. Under § 110.1(b)(1) you check the Energy Commission’s database (www.energy.ca.gov/appliances/database/). If the exact model number and serial/model family are listed as certified, that satisfies the code. For example: Model HPWH‑X100 — found in the database = acceptable proof. § 110.1(b).
Step 3 — If the model is not in the database. If HPWH‑X100 is not found, you must accept either (per § 110.0(b)3): a Commission‑approved directory listing the model, a copy of the manufacturer’s application plus Commission staff letter of acceptance for that model, written confirmation from a publisher of a Commission‑approved directory, or a Commission‑approved label physically on the unit. If none of those four are available and no approved directory data exists, compliance may fall back to § 110.1(c) procedures (default to mandatory efficiency levels or Commission‑approved procedures).
Result: If the database shows HPWH‑X100 is certified, you can sign off on the 12 units. If not, ask the installer/manufacturer for one of the four acceptable proofs listed in § 110.0(b)3 before permitting installation.

SECTION 100.1 — DEFINITIONS AND RULES OF CONSTRUCTION
(a) Rules of Construction.
- Where the context requires, the singular includes the plural and the plural includes the singular.
- The use of “and” in a conjunctive provision means that all elements in the provision must be complied with or must exist to make the provision applicable. Where compliance with one or more elements suffices, or where existence of one or more elements makes the provision applicable, “or” (rather than “and/or”) is used.
- “Shall” is mandatory and “may” is permissive.
(b) Definitions. Terms, phrases, words and their derivatives in Part 6 shall be defined as specified in Section 100.1. Terms, phrases, words and their derivatives not found in Section 100.1 shall be defined as specified in the “Definitions” chapters of Title 24, Parts 1 through 5 of the California Code of Regulations. Where terms, phrases, words and their derivatives are not defined in any of the references above, they shall be defined as specified in Webster’s Third New International Dictionary of the English Language, Unabridged (1961 edition, through the 2002 addenda), unless the context requires otherwise.

PG&E’s preferred PS arrangements are either: a) when the PS customer’s primary distribution line is underground (UG) and the POS is less than 500 feet from the property line, or b) when the PS customer’s primary distribution line is overhead (OH) and the protective device pole (if separate from the POS pole) is less than 50 feet from the property line.
- UG Conductor and POS < 500 Feet
If the PS customer’s primary line is underground and the POS is 500 feet or less from the property line, refer to Figure 1 on Page 12 and Figure 2 on Page 13. The following requirements apply:
A. The PS customer must provide a PG&E approved pad−mounted switchgear enclosure for PG&E’s revenue−metering equipment. See Section 12 on Page 13 for detailed revenue− metering requirements.
B. The PS customer must install primary protection at the POS. This protection may consist of a circuit breaker with phase and ground relays or, depending on the customer’s load, fuses may suffice. If PG&E determines that fuses will not coordinate with PG&E’s source−side protection, then the customer must use a circuit breaker. See Section 8A on Page 6 and Section 8C on Page 7 for circuit breaker and fuse requirements.
C. The PS customer must install conduit from the POS to PG&E’s primary distribution equipment location.
D. PG&E will pull one continuous run of cable and connect to the customer’s POS termination facility, not to exceed 500 feet (subject to an acceptable number of bends in the conduit).
- OH Conductor
If the PS customer’s primary line is overhead, then the first pole at the customer’s property line is the POS. Refer to Figure 3. The following requirements apply:
A. PG&E will install pole−top revenue−metering on the first pole on the PS customer’s property. See Engineering Standard 058779 Pole−Top Primary Metering Installation, (12 or 21 kV Line) for pole−top revenue− metering requirements.
B. The PS customer must install primary protection on the second pole on their property, not to exceed 50 feet from the revenue metering pole. This protection may consist of a recloser or, depending on the customer’s load, fuses may suffice. If PG&E determines that fuses will not coordinate with PG&E’s source−side protection, then the customer must use a recloser. See Section 8C on Page 7 for recloser requirements.
C. The PS customer second pole and the equipment installed on it, must maintain a minimum clearance of 10 feet from the PG&E revenue metering pole and any equipment, crossarms, and wires installed on it.
D. PG&E will interconnect its system with the customer’s system at the revenue−metering pole.
Section 4 Non−Preferred PS Arrangement Proposals
PS customers may propose a non−preferred PS arrangement. This typically occurs when the PS customer’s primary distribution line is UG and the proposed location for the primary switchgear is greater than 500 feet from the property line. PG&E will consider such proposals; however, non−preferred service arrangement proposals may take longer to

Frequently asked questions
How do I find the Energy Commission database referenced by the code?
The code points to the Energy Commission’s certified appliance database (www.energy.ca.gov/appliances/database/) as the primary verification source for Title 20 appliances per § 110.1(b)(1). Check that database for the exact model/family you are installing.
If a device has a manufacturer label, how do I know it’s a Commission‑approved label?
Only labels that are specifically Commission‑approved count under § 110.0(b)3(D). If the label references a Commission listing or certificate number, verify that number in the Commission’s database or with the Commission‑approved directory/publisher.
Can the enforcement agency require field testing of a certified device?
No. Part 6 explicitly states that the builder, designer, owner, operator, or enforcing agency is not required to test certified devices to determine compliance with minimum specs or efficiencies adopted by the Commission. Use the approved proof sources in § 110.0(b)3.
What if no directory lists the model I need to install?
When data is not available in the directories identified in § 110.1(b), § 110.1(c) allows demonstrating conformance by defaulting to Part 6 mandatory efficiency levels or following Commission‑approved procedures under Part 1 where applicable.
Is a manufacturer’s statement on a product sheet sufficient?
Not by itself. For non‑Title 20 items, Part 6 requires a declaration executed under penalty of perjury that the information is true and, if applicable, that required test procedures were used (see § 110.0(b)2). Additionally, confirm with one of the four acceptable proof methods in § 110.0(b)3.
