(A) The utility's standard service voltage is single-phase, 120/240 volts, three-wire, 60 hertz and is available to all consumers. Following is a list of all nominal voltage levels both single-phase and three-phase that the utility may elect to offer or require.
(1) 120 volts, two-wire, single-phase service (available only at the utility's option).
(2) 120/240 volts, three-wire, single-phase service.
(3) 120/240 volts, four-wire, three-phase service.
(4) 120/208 volts, Y-connected, four-wire, three-phase service.
(5) 240/480 volts, four-wire, delta three-phase.
(6) 277/480 volts, Y-connected, four-wire, three-phase service.
(7) At the utility's available primary voltage.
(8) At the utility's available transmission voltage.
(9) As to the availability of three-phase service, see division (C), below.
(B) Other voltages.
(1) Where the consumer desires service under voltage or phase conditions different than those the utility elects to furnish, any additional transformers, conversion or accessory equipment required shall be supplied and maintained by the consumer at his or her expense.
(2) The utility reserves the right to meter service at either primary or secondary voltage. In such an event, billing kWh shall be determined as is specified in the applicable schedule.
(C) Three-phase service.
(1) Normally only single-phase service is available. However, three-phase service may, at the utility's option, be furnished where three-phase facilities of adequate capacity are already installed immediately adjacent to the point where service is to be delivered to the consumer, or where, as determined by the utility, it is economically feasible to extend such three-phase facilities. See § 50.026.
(2) The utility reserves the right to refuse to extend or install three-phase facilities to serve motors individually rated at 20 HP or less and to furnish only single-phase service for such motors. In such an event, the consumer may elect to install single-phase to three-phase conversion equipment to operate his or her three-phase motors.
(D) Substation equipment. For large or unusual loads, the utility reserves the right to require the consumer to take service at primary voltage and to require the consumer to furnish the necessary complete substation equipment. In such an event, the substation ownership discount shall apply. See § 50.070.
(E) Temporary service. For provisions regarding temporary service, see § 50.025.
(F) Unusual extensions. Where an unusual extension of primary, secondary or transformer facilities are required (such as for three-phase service), the furnishing of service will be covered by a special written agreement, in conformance to the provisions set forth in § 50.026.
