(A) Service characteristics.
(1) The character of electric service available to each customer shall be at the city's option and shall be dependent upon the following:
(a) The service available at the proposed location;
(b) The size of the load; and
(c) The operation characteristics of the customer's equipment.
(2) The city's standard electric service is alternating current with a nominal frequency of 60 HZ. Direct current service is not available.
(3) Only 1 service voltage will be supplied for a single metered connection, except when an additional voltage is supplied on large power rate schedules, special or unusual service requirements exist, and service at 1 voltage is not practical in the city's opinion.
(C) Special requirements and limitations.
(1) Any single-phase utilization device having a rated capacity in excess of 2 Kilovolt-amperes shall not be operated at less than 208 volts without specific approval of the city.
(2) Three-phase service may be provided in any instance where, in the city's judgment, the customer's total connected load is of a size that 3-phase service is warranted. Where 3-phase service is supplied, any single-phase load shall be balanced on all 3 phases as closely as possible.
(3) Individual motors larger than 5 horsepower will not be served from single-phase circuits except with the advance approval of the city.
(4) All motors installed by customers after January 1, 1986, should have the appropriate associated capacitors installed. These capacitors will be disconnected and connected to the electric service with a motor.
(D) Primary connections available. Service at primary voltage will be available for large power loads at voltages designated by the city as the service voltage available in the area for the size of load to be served.
(E) Overhead service. Generally, except as otherwise provided in the following sections on underground services, and unless an area is specifically designated by the city as a DESIGNATED UNDERGROUND AREA, the normal method of customer service will be by overhead service conductors from the city's overhead distribution system.
(F) Underground service. The city will install underground electric distribution services or systems under the following conditions, provided the service is not readily available from adequate existing city-owned overhead facilities.
(1) Optional underground extensions.
(a) In all service areas not designated underground commercial service areas pursuant to division (F)(2) below, and where a single or 3-phase primary extension and separate transformers are required to serve a new large power classification customer, the city will furnish, install, own and maintain a 15 kV underground primary extension as a customer option to an overhead primary service extension, provided the customer agrees to dig and backfill the entire trench and to furnish all conduits (including riser on city-owned pole), ducts and similar materials, in accordance with city specifications.
(b) In addition, the customer will be required to grant to, or secure for the city, a suitable utility easement, at no cost to the city, for the entire length of the underground primary extension, including the easement for property not owned by the customer.
(c) The customer will also be required to provide facilities for transformer location as noted in division (F)(2) below.
(d) The customer is responsible for trenching the total original distance required to serve the customer, including all necessary crossings of streets, other roadways and parking lots, on either public or private property. When any improved surfaces are disturbed, the customer shall return the surfaces to a condition at least as good as they were before being disturbed.
(e) The surfaces shall also comply with all applicable city code provisions. The customer is responsible for defects or adverse surface conditions resulting from improper backfilling and/or resurfacing of the original trench. The city will assume maintenance responsibility for the underground primary extension when it is properly completed.
(2) Required underground extensions. In any portion of the city's electric service area with existing or potential commercial or industrial customers, the city shall have the option to designate an area as an underground commercial service area at any time a service request is received, as part of its planning for future service requirements. The standard conditions of electric service in the area will be as follows.
(a) For customers requiring separate transformer installations, as determined by the city upon consideration of voltage, capacity, space limitation or other requirements, the customer is required to provide at the customer's expense 1 of the following:
1. Suitable facilities for an outdoor pad mounted transformer installation (including a concrete pad, switches and conduits);
2. A suitable transformer vault for oil filled transformers; or
3. Equivalent arrangement necessitated by special conditions when approved by the city.
(b) All conduit or duct into and/or within the customer's vault or building as required for the city-owned primary service cable in conformance with city specifications.
(c) All secondary cable and cable terminals beyond the transformer terminals. The customer is also required to own and maintain these items.
(d) The city will provide the underground primary service cable which will connect to or terminate on the primary disconnecting device associated with the transformers installed in the space provided.
(e) For customers not requiring separate transformer installations, the city will provide a secondary terminal at an accessible location on or adjacent to the customer's property.
(f) The customer will provide underground secondary service cable with terminals which will terminate on the city's secondary terminals. The cable must be compatible in all respects with the city's distribution system.
(g) The city will make all final connections to its secondary terminals.
(h) The city's meters may be installed, at its option, either at the secondary terminals or at the customer's building pursuant to the provisions for metering described in § 54.05(F) below.
(i) Pole mounted transformer installations will be used in an area only at the city's option.
