(A) Equipment ownership. The city will supply, own and maintain all meters and metering equipment necessary to measure the electric power and energy used by customers, unless otherwise agreed for some special service.
(B) Delivery points.
(1) The city's standard rate schedules provide that all service taken under any rate schedule shall be delivered to only 1 delivery point, through 1 service connection and 1 meter or metering installation.
(2) If a customer requires service to 2 or more delivery points, then a separate meter will be installed at the additional delivery points, and each metering point shall be considered a separate service, requiring a separate application, or agreement and energy used at each delivery point will be billed separately at the applicable rate schedule.
(C) Additional meters.
(1) If a customer desires an additional meter or wiring installed for the customer's convenience, the cost shall be charged to the customer and shall be paid at the time of installation.
(2) The city will not permit additional meters (either city or customer owned) to be installed by any customer for the purpose of sub-metering the electricity use by some other person, firm or customer.
(D) Metering installations and types.
(1) Metering sequence.
(a) A meter-switch-fuse sequence is an installation where the metering equipment is connected on the supply side of the customer's main disconnect supplying the load to be metered.
(b) The meter-switch-fuse sequence arrangement shall be followed on all secondary metering installations except where, at the city's option or to meet requirements of the National Electrical Code, this type of installation is not practical because of existing conditions.
(2) Meter location.
(a) Meters shall be installed so that the top of the meter shall be between 5 feet, 6 inches and 6 feet above the floor or ground.
(b) Meters shall be located in a clean, dry place, free from vibration, steam, other vapors or abnormal dust; shall not be located above any stored supplies, pieces of household or commercial equipment, where they will be subjected to abnormal temperatures or in a location which is hazardous for city representatives to read or test the meters; and shall be readily accessible at all reasonable hours.
(3) Outdoor self-contained metering. Outdoor metering installations are required for all new building construction or remodeling work when service entrance wires are changed, where service is supplied from overhead service drops for 1 customer's use, except in business areas, or where the single-phase load exceeds 200 amperes.
(a) The customer shall provide the service entrance conductors from the customer's weatherproof service head to the customer's service switch cabinet.
(b) The metering equipment is to be installed outside the building in the service conduit or service entrance cable.
(c) The city will supply the meter enclosure or socket meter base, but this enclosure or base will be installed at the customer's expense and at a city-approved location. If the customer does not want the entrance conductor cable on the outside of the building, then the customer shall install the entrance conductor cable on the inside of the building and provide proper facilities for connections to the outside of the building for the city's meter to be installed in the service entrance conductors.
(d) The city will supply and install the meter, and own, maintain and replace the meter and meter enclosure or socket meter base when necessary.
(4) Indoor self-contained metering.
(a) The service entrance conduit or cable to be installed by the customer shall be brought into the main service panel in a continuous conduit or cable, without any provision for disconnection or connection to any other conduit. The length of the service entrance wire to the customer's main service panel shall be as short as possible.
(b) The customer shall provide space for the city to install the meter or meters adjacent to the entrance disconnect device. The city shall not permit switches to be installed on the supply side of the meter where covers cannot be sealed, thereby preventing access to the wiring.
(c) If the city decides present indoor metering is unsatisfactory, the city reserves the right to install outdoor metering at its own cost and expense.
(5) Instrument transformer metering installation.
(a) All services requiring 300 volts or more and/or all services for a capacity over 200 amperes will be metered with instrument transformers.
(b) The city will install, own and maintain all metering equipment, devises, wiring and accessories except, at the request of the city, the customer shall provide sealable meter cabinets of sufficient size to enclose the instrument transformers with proper clearances when the instrument transformer metering is installed indoors.
(c) Furthermore, the customer must contact the city for proper location of the metering equipment. In all cases, the enclosure for the instrument transformers should be installed in the conduit run on the supply side of the customer's main entrance switch or disconnect switch and fuses, otherwise provisions of division (D)(4) above shall apply.
(6) Metering multiple occupancy buildings.
(a) The city will supply, own and maintain gang-type metering sockets in standard groupings as adopted by the city for multiple occupancy buildings where ganged type meter installations are desired.
(b) Meter sockets owned by the city will not be the combination type that includes line or load switches or facilities for installing these switches and/or overcurrent devices.
(c) Combination equipment may be installed in lieu of city-owned meter sockets, provided the customer owns, installs and maintains the facilities.
(d) The city will not share in the ownership of the equipment and will not reimburse others for sockets not supplied by the city.
(e) The customer will be required to furnish, install, own and maintain all conduits, troughs, wiring and similar equipment needed to mount and connect ganged socket assemblies.
(E) Accuracy of meters and meter testing.
(1) All electric watt-hour meters placed in service shall be certified to be accurate within the following tolerances when under the following test load conditions.
Percent of Test Current | Power Factor | Tolerances |
100 | 1.0 | +/- 1.0% |
10 | 1.0 | +/- 1.0% |
100 | .5 | +/- 2.0% |
(2) Meters and associated devices will receive in-service performance tests in accordance with the city's meter testing schedule.
(3) Inspections are made to determine proper operation and wiring connections and must be made within 60 days after installation by a qualified person other than the original installer, if possible.
(4) The following equipment is subject to post-installation inspections:
(a) Meters associated with instrument transformers, excluding single-phase current transformer metering installations or phase shifting transformers together with all like associated equipment;
(b) Kilovar-hour meters; and
(c) Demand meters.
