Current through Register 2024 Notice Reg. No. 50, December 13, 2024
Section 4027.5 - UR. User Requirements
UR.1. Selection Requirements.
UR.1.1. Meter Class. The meter class shall equal or exceed the total capacity in amperes of the thermal overload protectors of the tenant.
UR.1.2. Suitability of Equipment. A meter shall be suitable for use on its electrical system. A 3-wire two-phase load which is connected to a 120-208 volt network service shall be metered by a two-stator or two-element meter.

A meter shall accurately measure all loads 5 percent or greater of the electric service capacity of the tenant. Service capacity shall be determined by the master thermal overload protectors to the tenants' service or by the rated capacity of an electric cord and its connector used to provide power from the service panel to the tenant.

UR.1.3. Instrument Transformer Ratio. The instrument transformer shall be correctly matched to the meter indicator and multiplier.
UR.2. Installation Requirements.
UR.2.1. Regulation Conflicts and Permit Compliance. If any provision of this section (UR.2. Installation Requirements) is less stringent than that required of a similar installation by the serving utility, the installation shall be in accordance with those requirements of the serving utility.

The installer of any new electric watthour submeter service shall obtain all necessary permits and shall conform to California Public Utilities Commission (CPUC) Decision D 05-05-026, including but not limited to conformance with Section 8 of Pacific Gas and Electric Company (PG&E) Greenbook requirements.

(Nonretroactive as of February 12, 2009).

UR.2.2 Certification by Serving Utility or Public Utilities Commission. It is the responsibility of the owner of the submeter system to obtain written certification for each submetered service connection from the serving utility or from a person designated as qualified by either the serving utility or by the California Public Utilities Commission (CPUC).

The required certification shall identify the address, space, or number, of the premise served by the submeter connection, be signed by an authorized serving utility representative or by a designee, and shall clearly state:

a) the installation meets all serving utility installation and accessibility requirements for similar installations served directly by the serving utility,
b) the installation is on a tariff schedule that qualifies for submeter use,
c) the billing format, rates, and charges conform to Public Utilities Code Sections 739.5 or 12821.5 and to all applicable serving utility tariff rules,
d) the installation complies with CPUC Decision 05-05-026
e) the date of such determination, and
f) if performed by a designee, the designee's name and title, and the name and title of the serving utility company or Public Utilities Commission representative authorizing the designee to make the determination.

The certification shall be provided to the county sealer prior to a submeter being used for commercial purposes.

(Nonretroactive as of February 12, 2009).

UR.2.3. Meter Test Facilities. All meters shall be provided with the same test facilities required of a similar meter by the serving utility.
UR.2.4. (MM) Test Blocks. All three-phase self-contained meter installations shall be equipped with test blocks, which are approved by the serving utility, for safe meter testing.
UR.2.5. (MM) Test Switches. Meter installations that are equipped with current or potential transformers, or both, shall have test switches installed, which are approved by the serving utility, for safe meter testing.
UR.2.6. (MM) Circuit Closing Devices. All self-contained meter installations that cannot accept a short interruption of the electrical service, for the purpose of testing the meter, shall be equipped with a manual circuit closing device as approved by the serving utility. Automatic circuit closing devices shall not be used on any meter installation.
UR.2.7. Metered Circuits (Load Service). All electricity used by a tenant shall be taken exclusively from the load service of the tenant's meter. This service and its associated meter shall accurately measure the tenant's load and be capable of being used only at the discretion of the tenant.
UR.2.8. Unmetered Circuits (Line Service). The tenant's electric circuit shall not be taken from the line terminals of the meter, meter socket, or line service. The owner of the submeter system may utilize this service.
UR.2.9. Dedicated Tenant Service. A meter shall serve only the space, lot, building, room, suite, stall, slip, or premise occupied by the tenant.
UR.2.10. Tenant Premise Identification. Tenant premise identification shall be clearly and permanently shown on or at the meter, and on all separate components of a meter system, including, but not limited to, instrument transformer(s), modem(s), and transmitter(s) if equipped. Remote indications and all printed indications shall be readily identifiable and readily associated with the tenant's premise. Printed indications shall also include time and date information.
U.R.3. Use Requirement.
UR.3.1. Submeter Required. When a tenant is not directly served by the serving utility, and charges for electric energy are not included in the fixed periodic rent charges, a dedicated electric watt-hour submeter that measures only the energy used at the discretion of the tenant shall be used.
