(a) Character of Service. The phase, voltage, size and types of all motors installed by customers shall be subject to the approval of the Borough. Customers shall, as provided for and regulated by this chapter, install motor starting devices, automatic circuit breakers, switches, fuses or overload devices of a type approved by the Borough, and shall adjust, renew or replace the same from time to time or on request of the Borough. The Borough Manager may issue regulations concerning the method of starting motors in order to keep excess current required for such starting as low as practicable, without in any way rendering the Borough responsible for control or operation of any such equipment. The voltages and phases of motors which may be part of the customer's installation to which the Borough supplies service shall conform, as applicable, to the following requirements:
(1) A motor rated one-half horsepower or less shall be a single-phase motor and shall be rated for connection to 120-volt or 240-volt single-phase circuits.
(2) A motor rated larger than one-half horsepower, but not exceeding five horsepower, shall be single-phase and shall be a motor rated for connection to 240-volt single- phase circuits. A motor rated larger than one-half horsepower, but not exceeding five horsepower, shall not be rated for connection to 120-volt single-phase circuits.
(3) A motor rated in excess of five horsepower or a group of motors having combined horsepower rating in excess of five horsepower shall be connected only for three-phase operation and only where the Borough supplies polyphase service to the customer's installation.
(4) Motors frequently started or motors arranged for automatic control shall be of the type to give maximum starting torque with maximum current, and shall be equipped with controlling devices approved by the Borough. At the customer's expense, the customer shall, as provided for and regulated by this chapter, install a reverse-phase relay of approved type on every alternating current motor used for passenger or freight elevators, hoists, pumps or cranes.
(5) Notwithstanding the requirements set forth in paragraphs (a)(1), (2) and (3) hereof, the Borough Manager may authorize a connection of a motor or a group of motors to a voltage or a phase other than in accordance with the aforesaid requirements where, in the opinion of the Borough Manager, the required type of connection would impose a hardship upon the customer and the proposed connection would not interfere with the Borough's electric distribution system or with the rendering of electric service to any other customer of the Borough.
(b) Fluorescent and Neon Lights. As provided for and regulated by this chapter, customers shall install, in connection with any fluorescent or neon lighting or other lighting or display facilities having similar load characteristics, auxiliary equipment designed to correct the power factor of such installations to not less than eighty-five percent.
(c) Low Power Factor Equipment. The Borough shall not be obligated to furnish service for gaseous tube lighting, air conditioning equipment or other types of electrical equipment having a power factor lower than that of available good quality, high-power factor equipment. If power factor corrective equipment is necessary, it, together with required switching equipment, shall be provided and maintained by the customer at his or her expense. Static power factor correction shall at no time exceed one-third of the amount of the demand.
(d) Capacity Limitation. The Borough will not supply single-phase service to any customer's installation where the connected load exceeds fifty KVA. In instances where the connected load exceeds fifty KVA, the customer shall, as provided for and regulated by this chapter, arrange or rearrange the customer's installation to accept polyphase service which will be supplied by the Borough. The Borough will not supply polyphase service at a secondary voltage where the customer's demand exceeds 300 KVA unless otherwise authorized by the Borough Manager.
Single-Phase Source Derived From Polyphase Service. Only transformers with separate primary and secondary windings shall be utilized where the customer's installation is arranged to derive single-phase power from the polyphase service supplied by the Borough. Auto transformers, balance coils or means other than a transformer with separate primary and secondary windings shall not be utilized for such purpose.
Safety Disconnect Switch. A safety disconnect switch shall be provided at the entry to all spaces housing a solid or liquid fuel furnace or boiler. In the case of furnace or boiler rooms, the switch shall be located on the exterior wall of said room. In dwelling units, the switch shall be located inside the entry to the area containing the furnace or boiler.
Marking. In all panelboards, each and every means of disconnect and overload protection shall be clearly marked, indicating the circuit controlled and protected by such device. The required marking shall indicate room(s) and whether receptacles and/or lighting circuits are controlled and protected, plus any designated circuits.
Overcurrent Protection. Overcurrent protection shall consist of either “S”-type fuses, circuit breakers or noninterchangeable cartridge fuses.
Protection of Equipment. Protection of equipment against loss of voltage, undervoltage, transient or sustained overvoltage, voltage unbalance, overcurrent, phase failure, phase reversal, loss of synchronism and short circuit shall be the responsibility of the customer. (Ord. 2211. Passed 4-29-97.)
Customer-Owned Emergency Generation Systems. No person shall operate a customer- owned generation system except as provided herein and only as a customer-owned emergency generation system.
Emergency systems. Emergency systems shall be those systems legally required and classed as emergency by Municipal, State, Federal or other codes, or by any governmental agency having jurisdiction. These systems shall be intended to automatically supply illumination or power, or both, to designated areas and equipment in the event of failure of the normal supply or in the event of accident of elements or a system intended to supply, distribute and control power and illumination essential for safety to human life. The installation, operation and maintenance of emergency systems, including emergency generators, shall comply with the requirements of the National Electrical Code.
Generation systems. Customer-owned generation systems intended to provide power during the interruption of the normal electrical service supplied by the Borough shall be permitted subject to the following requirements:
Equipment. The installation, operation and maintenance of generation equipment shall be required to be approved by the Borough and shall comply with the National Electrical Code.
Electrical interconnection. No electrical interconnection between the Borough's system and the customer generation equipment shall be permitted at any time.
Double-throw switch. The customer shall install, in a manner approved by the Borough, a double-throw switch so that there can be no electrical interconnection between the Borough service and the customer generation system.
The double pole switch may be manual or automatic and shall be of adequate rating with respect to voltage and current. The double throw switch shall be of break before make type to maintain complete electrical isolation of customer generation from the Borough system.
Where the National Electrical Code permits, and the customer elects to install, the double pole switch on the supply side of the customer's main service disconnect and overcurrent protective device, the double-pole switch shall be listed for use as service entrance equipment.
Noncompliance; liability of customers. The customer's failure to follow these regulations shall create liability for the customer for any and all damage to Borough-owned electric equipment facilities and equipment and to persons, as well as any damage to other property of customers of the Borough.
