1.0 INTRODUCTION These Customer Requirements for Electric Service are published as a reference for Customers, Contractors, Architects, Engineers and other interested parties who may be concerned with installation considerations that the Company s experience has shown to be necessary in order to provide safe and satisfactory electric service. It is the intention of the Company that the Customer s service facilities requirements in this booklet shall be consistent with all applicable federal, state, county and municipal regulations, laws, codes, and ordinances as may be in effect now or hereafter in the areas served by this Company. To the extent such governmental regulations are more stringent than the requirements herein, the governmental regulations shall control. To the extent such governmental regulations are less stringent, the requirements herein shall control. Requirements herein are not necessarily complete facility or safety specifications. Rather, they cover matters of mutual concern to the Customer and the Company, which facilitate the supplying of electric service. The requirements are subject to revision from time to time without notification so that they keep pace with developments and progress in the electric industry. Compliance with these requirements does not absolve the Customer from obligation to install and maintain wiring and equipment in a safe condition; also, the Company does not accept any responsibility for the quality or condition of the Customer s wiring and equipment. The Customer shall comply with the latest edition of the National Electrical Code (NEC) and all applicable safety codes and practices. Unless otherwise noted, statements and drawings in this booklet refer to services of 600 volts or less. Contact the Company with questions regarding services at higher voltages and special residential, commercial and industrial requirements. The Company s Rate Schedules and associated Rules and Regulations for all classes of service will be furnished to any Customer upon request. These Customer Requirements for Electric Service are supplementary to those contained in the formal Tariffs currently on file with regulatory agencies having jurisdiction over the Company s operations. Unresolved disputes that a Customer has with the Company regarding the requirements of this booklet may be resolved by the appropriate State Commission. Mandatory rules of this document are those that identify actions that are specifically required or prohibited and are characterized by the use of terms shall or shall not. 1

However, the Company shall not be liable for any loss, cost, damage or expense to any Customer occasioned by any failure to supply electricity according to the terms of the contract, or by an interruption or reversal of the supply of electricity, if such failure, interruption or reversal shall be due to the elements, public enemies, strikes or order of Court, which are beyond the control of the Company, or any cause except willful default or neglect on its part. Unless caused by an unreasonable practice of the Company, the Company may, without liability, interrupt or limit service to any or all Customers whenever, in the sole judgment of the Company, such action is necessary in order to prevent or limit any actual or threatened instability or disturbance on the electric system of the Company or any electric system interconnected with the Company. Customers should be aware that they could occasionally experience intermittent power interruptions. Since most interruptions are temporary, the Company designs its electrical system to clear these intermittent interruptions without permanently interrupting electric service. 4.14 RIGHT TO REFUSE OR DISCONTINUE SERVICE Since it is the Company s obligation to provide safe and satisfactory service to all Customers, the Company reserves the right to refuse or discontinue service without notice if, in the opinion of the Company, the Customer s wiring, equipment or appliances are unsafe for receiving electric service or are harmful to the service of other Customers. The Company will make a reasonable effort to notify the Customer prior to disconnection and shall inform the Customer of the steps that shall be taken to have service restored. The Company reserves the right to refuse or discontinue service with or without notice, and without liability, under various circumstances other than those mentioned above. These circumstances are set forth in the Company s Tariff as filed with the applicable regulatory agencies and the rules and regulations of the commissions.

7.0 CUSTOMER EQUIPMENT 7.01 GENERAL The Customer shall notify the Company prior to adding electrical equipment so that facilities of proper capacity may be provided to assure satisfactory operation of the Customer s equipment and to protect both the Customer s and the Company s equipment against damage. The Customer is required to provide protection that will prevent damage to equipment from normal operations of the Company s supply system. This equipment includes motors, welders, heating equipment, voltage sensitive devices, harmonic producing equipment, x-ray equipment, and other equipment that may require special starting and protection. 7.02 MOTOR INSTALLATIONS It is characteristic for most motors to draw a heavy momentary current on starting. The starting current for A- C motors can be on the order of three to ten times the normal running current. If sufficient capacity is not present in the Customer s circuits and in the Company s facilities serving them, the motor may not start properly, resulting in overheating, blown fuses or damage to the motor and other equipment. In addition, it may result in excessive voltage fluctuations and light flicker that may be objectionable to the Customers using the motor, as well as to other Customers supplied from the same lines. It is, therefore, necessary for the Company to place restrictions on the starting current of a motor either by limiting the size of the motor or by requiring the Customer to install suitable starting devices. Motors installed should be suitable for operation at the service voltage available. The Customer shall consult the Company (1-800-255-3443) prior to purchasing or installing any motor to verify the voltage, frequency and phase characteristics of the services to be supplied, the capacity available, and the suitability of the proposed equipment for operation at the intended location. *Upon proper application, the Company will investigate the possibility of serving single-phase capacitor start, capacitor run motors larger than 6.5 hp where such service does not adversely affect our Customers. **Three-phase supply is not available for residential rate schedule service. For poly-phase motors and equipment to be operated at voltages other than 240 volts, the locked rotor currents specified for 240 volts shall be multiplied by the inverse ratio of the voltages. Where equipment, ratings or starting characteristics other than those covered in the preceding table are being considered, the Company will furnish information regarding higher starting currents for single-phase motors and 3-phase motors which will be permitted under specific conditions. Permissible starting currents will depend upon the size of the motor, the frequency of the starting, the character of the Customer s load, and the design and capacity of the Company s supply system in the area. Generally, this will be equivalent to the maximum starting current that, in the Company s opinion, can be supplied without causing undue interference with service to other Customers. Whenever a starting current that is not covered in the preceding table causes undue interference with service to other Customers, the Customer shall provide a starting device of a type that will reduce the starting current to the value required to eliminate such interference. The Customer shall contact the Company prior to the installation of any D-C motor or adjustable speed drive. The following maximum permissible motor starting currents shall apply to the installation of motors: Equipment for Operation at: Total Locked Rotor Current Not to Exceed: Single-Phase 120 volts 50 amp 240 volts 2 hp or less 60 amp 2 hp to 6.5 hp 60 amp plus 20 amp per hp in excess of 2 hp Over 6.5 hp Consult Company* Three-Phase 240 volts** 2 hp or less 50 amp 2 hp to 19.9 hp 50 amp plus 14 amp per hp in excess of 2 hp Over 19.9 hp Consult Company 13

7.03 REQUIRED EQUIPMENT PROTECTION It is the Customer s responsibility to provide protection in accordance with the Customer s requirements and any applicable codes. Specifically, the use of phase-failure and phase-reversal relays, are required on all new poly-phase motor installations. It is also highly recommended that existing poly-phase motor installations be retrofitted with phasefailure and phase-reversal relays to protect the motors from damage. Single-phasing conditions in the electrical supply system may damage motors. The Customer has several options to provide phase-failure and phasereversal protection. Some of the options are as follows: (a) One phase-failure and phase-reversal device may protect single motor or a group of motors. (b) The phase-failure and phase-reversal device can be installed on each motor and open all motor contacts and/or the device can activate an alarm to alert the Customer that a phase-failure or reversal condition exists. The Company will not be responsible in any way for damage to the Customer s equipment that is due to failure of the Customer to provide adequate protection. 7.04 AIR CONDITIONERS, CENTRAL SPACE HEATING, HEAT PUMPS, INCLUDING SUPPLEMENTAL HEATING ELEMENTS IN HEAT PUMPS Thermostatically controlled electric furnaces, boilers, and supplemental resistance heating elements in heat pumps with an installed capacity greater than 12kW shall be switched in 6kW (max.) increments at minimum intervals of 10 seconds, whether incrementally increasing or decreasing the load. For installations greater than 24kW, the Company shall be consulted to determine staging parameters, unless switching can be accomplished in stages of 6kW as indicated in the preceding paragraph. A Customer, installing a heat pump or air conditioner, in excess of 5 ton (single-phase) or 20 ton (three-phase), shall contact the Company prior to installation of the equipment. 7.05 ELECTRIC WATER HEATERS The heating elements of residential electric water heaters and tank-less water heaters shall be limited to a maximum of 5,500 watts each, shall be 208 or 240 volts, thermostatically controlled and connected to prevent simultaneous operation. All water heaters shall be equipped with an American Standards Association approved pressure-temperature relief valve located in the top of the tank, a two-pole, manual reset over-temperature cutoff switch with 190 o F maximum cutoff of electric supply and UL listed. Water heater elements exceeding these parameters may cause excessive flicker to Customer. The Company shall be consulted before installing electric water heating equipment with heating elements in excess of 5,500 watts. The Company is not responsible for unsatisfactory service resulting from the operation of such water heaters installed by Customer without consulting Company. When the installation of residential electric water heating equipment with heating elements in excess of 5,500 watts requires additional facilities, Customer shall pay the costs of additional facilities beyond those facilities normally furnished by the Company. All bathtubs, showers, sinks, and washtubs shall have all their metallic parts, metallic water pipes, and metallic drainpipes bonded and grounded. 7.06 ELECTRIC WELDING, X-RAY, RADIO, ELECTRONIC EQUIPMENT, ETC. Electric welding equipment shall not be connected to the Company s lines without first consulting the Company. Electric welding equipment may cause serious flicker in the Customer s lighting as well as that of other neighboring Customers. On rural lines and urban residential distribution systems, welding equipment shall be limited to a maximum of 50 amperes when supplied at 240 volts. A transformer-type welder is recommended for use on the Company s lines. Straight resistance line voltage welders are not acceptable. Electric apparatus (such as X-ray equipment, radio, television and electronic transmitting equipment, and other electronic applications), which have an adverse effect on the Company s ability to supply adequate service to all its Customers, shall not be installed on and operated from the Company s lines until the Customer has secured specifications and available capacity from the Company. 7.07 LIGHTNING AND SURGE PROTECTION The Company provides protection on its lines to minimize damage from lightning. The Company will not be responsible for damage to Customer s equipment because the Customer did not provide adequate lightning or surge protection or due to the failure of any such devices. 7.08 THREE-PHASE CONVERTER Phase converters may be used to supply energy to 3-phase motors from a single-phase service. 3-phase motors served from phase converters may cause serious flicker in the Customer s lighting or adversely affect the operation of other equipment in the Customer s premises. The phase converter shall be sized properly for the load to be 14

served in order to minimize the magnitude of voltage fluctuations caused by motor starting. The Company shall be consulted before a phase converter is installed to insure that its operation will not affect other neighboring Customers. The Company reserves the right to refuse service to a phase converter installation if it is determined that it would adversely affect the Company s ability to supply adequate service to all its Customers. 8.0 METER INSTALLATIONS 8.01 GENERAL Meters and meter testing devices are furnished, installed and maintained by the Company. They remain the property of the Company and shall not be moved or the connections changed by any person other than authorized employees of the Company. All metering shall be installed on the line side of the Customer s main disconnecting means except for a 480Y/277 volt metering installation where the Company requires a meter disconnect ahead of the meter or where the NEC requires a main disconnect ahead of a group of more than six (6) meters. See Figures 42, 43 and 45 for self-contained, 480Y/277 volt, 4-wire metering installations. Consult Company prior to purchasing or installing equipment. Meter sockets, metering transformer cabinets and all other enclosures and switchboxes installed on the line side of the meter shall be equipped with provisions to accept a Company meter seal before connection will be made by the Company. Meter sockets, transformer cabinets, and other meter service enclosures are not to be used by the Customer as junction boxes only service entrance conductors are permitted. Metered and unmetered conductors shall not be installed in the same conduit, enclosure or raceway. Any energized meter socket must be properly covered at all times when the meter is not in place. Meter sockets and service conduits shall not be recessed into the wall. Unmetered service entrance cables or service entrance conduits on buildings, poles or structures shall not be concealed or recessed. Meter installations that have the meter socket as part of a pedestal, multi-metered equipment, or attached to or an integral part of customer-owned service equipment shall be approved by the Company prior to purchase and installation by the Customer. The Company, in accordance with the rate schedule selected and the type of service supplied, determines the capacity and type of meter installation to accommodate the Customer s load. 8.02 METER LOCATIONS The Customer shall provide space for the installation of the Company s meters and equipment at an outside 15 location designated by the Company. Outdoor meter locations are required for all meters except where the Company gives approval otherwise. For residential single-family, duplex and townhouse dwellings, the meter socket shall be located outside within 15 feet of the nearest corner of the dwelling to the Company facilities. If this location is not feasible due to physical obstructions, such as garage doors or windows, the Company will choose an alternate location closest to its service facilities (see Figure 40). The meter socket shall be installed so that the top of the socket is not more than 5-6 or less than 4-0 above the finished grade. Meter socket height for pedestals, multimetered equipment, or meter sockets attached to or an integral part of customer-owned service equipment shall be approved by the Company. The Customer shall provide at least 15 of clear space on all sides of the meter as well as 30 in front of the meter. The above clearances shall be maintained regardless of structural changes of the building. The Company will not accept a meter to be located in an area which could be dangerous to meter readers or testers, or where conditions would prevent the meter person from standing in front of the meter to test or read. Meters, meter sockets and metering transformers shall not be located in a manhole or any similarly classified location. A meter may be located on a Customer-owned pole with prior Company approval. This pole shall be yellow pine, cedar or equivalent, pressure-treated and provide proper clearances (see Figure 1). Before installing pole, consult the Company (1-800-255-3443) for proper size and setting depth (see Figures 5, 6, and 7). Any metering installation on a Company-owned pole shall have the specific written approval of the Company. 8.03 METER RELOCATIONS When alterations or additions to a building or its wiring require a change in meter location, the Customer shall notify the Company before proceeding with any work. The Customer may be responsible for the Company s costs for facility modifications. The Customer shall be responsible for all costs incurred in moving the socket and wiring. 8.04 EMERGENCY METER REMOVAL Firefighters and other emergency personnel SHALL NOT remove electric meters during fires or other emergencies. Removing a meter MAY NOT de-energize the building or contribute to the safety of firefighters or emergency personnel. 8.05 GROUP METER INSTALLATION In serving groups of residential or commercial installations, provisions may be made to group meters at a single location that will be accessible to the tenant and

to the Company (see Figures 43, 44 & 45). The Customer is responsible for permanently labeling each meter socket with its corresponding apartment, office, etc. being served. Labeling shall be by stenciled paint, engraving, stamping or riveted metal tag. In large buildings, special conditions may make it desirable to group, on each floor or area, the meters for individual Customers located on that floor or area. Detailed plans of such installations shall be submitted to the Company for approval before construction is started or equipment purchased. When it is necessary that the Customer install a main/service disconnecting means because of the number of meters, this disconnecting means shall be sealed and the Customer will be permitted to break the switch seals only for the purpose of replacing fuses or for maintenance. In such instances, the Customer shall promptly notify the Company that the seals have been broken. 8.06 TRANSFORMER-RATED METER INSTALLATIONS All transformer-rated metering enclosures (including metering current and voltage transformers) shall be prewired and furnished by the Company and installed by the Customer. Consult the Company for details (see Figures 47, 48 & 49). Provisions shall be made for the installation of metering transformers for single-phase or 3-phase services in excess of 320 amperes. Metering transformers are normally installed on the line side of all service protective equipment, except where the NEC requires a main disconnect ahead of the metering. When overhead service is provided, the metering transformer(s) will normally be of the outdoor-type and mounted sufficiently high, on the outside of the building, so that a transformer enclosure is not required (see Figures 11 & 50). When a busway is used for the service entrance conductors, the Customer shall mount metering transformers, furnished by the Company, in the busway. Metering transformers may be installed in Customerowned transformer vaults, cubicles, switchgear or on switchboards, when prior arrangements are made with the Company. Meters, meter sockets and metering transformers shall not be located in a manhole or any similarly classified location. Sufficient access and working space shall be provided and maintained about all metering equipment. The meter socket shall be located outside and be mounted so that the top of the socket is between 5-6 maximum and 4-0 minimum above finished grade and within 30 (cable length) of the current transformers. If changes are made on the premises, thereby making the existing meter location unsafe or inaccessible for reading or testing, the Customer shall be required to make the 16 necessary changes to correct the situation. Customer-owned equipment shall not be connected in the secondary metering circuit. 8.07 TRANSFORMER-RATED METERING AT PAD- MOUNTED TRANSFORMER The preferred location for transformer-rated metering will be at the Company-owned, pad-mounted transformer. The Customer shall be required to provide all facilities on the load side of the metering. For remote metering communication requirements see Section 8.08. The Company shall be consulted regarding necessary space requirements and equipment to be furnished and installed by the Customer. 8.08 METERING COMMUNICATIONS The Company may require remote interrogation of metering when the assigned rate schedule deems interval metering is required. When the Company deems remote interrogation is required, the following shall apply: (a) Transformer Rated Metering At Pad- Mounted Transformer Customer shall furnish and install a 1-1/4 conduit and 1/4 nylon or polypropylene pulling rope from the secondary compartment of the pad-mounted transformer to a location at the Customer s building where telephone line service can be made available at the telephone company s demarcation point. Once the conduit from the pad-mounted transformer enters the building, cable may be used to the demarcation point or the conduit may be continued to the demarcation point (See Figures 24, 28, and 29). Consult Company for details prior to installation. (b) Transformer Rated Metering Cabinet or Channel Package Customer shall provide access (cable or conduit) to the telephone company facilities (demarcation point) within 5 feet of the meter socket on the same wall surface exclusively for Company remote metering purposes. Conduit shall be a minimum 1-1/4 diameter, with a 1/4 nylon or polypropylene pulling rope from the meter point to the telephone company facilities (See Figures 23, 48, 49 and 50). Consult Company for details prior to installation. 8.09 SEALS The Company will seal all meters and points of access to the wiring, ahead of the meter. All cabinets, switchboxes, terminal boxes, etc., either inside or outside the building, which contain unmetered wires, shall be made sealable by the Customer before service will be supplied. Where

equipment is not arranged for sealing, 1/8 diameter holes shall be provided by the Customer for sealing purposes. All service entrance conduit fittings used outside the building ahead of the meter shall have nonremovable covers. All such fittings used inside the building ahead of the meter, if not of the non-removable cover-type, shall be drilled for sealing. The Company prohibits the breaking of Company seals by unauthorized persons, or tampering with meters or with any wiring equipment located ahead of the meter. 9.0 METER SOCKETS 9.01 GENERAL A self-contained meter socket will be used for singlephase and 3-phase electric service not exceeding 320 amperes at service voltages less than 600 volts.
