While this book should answer most questions, you may contact Cody’s Electrical Division for further assistance. The appropriate phone numbers and contacts are: City of Cody Electrical Engineer – 527-7511 City of Cody Electrical Superintendent – 587-6803 City of Cody Building & Electrical Inspector – 527-7511 The word “Utility” as used in this booklet shall mean the City of Cody Electrical Division. The word “Customer” shall mean the resident, building owner, contractor or developer requiring electrical service. 1.02 Codes and Ordinances The construction of new or remodeled electrical installations must conform to applicable provisions of the National Electrical Code, the National Electrical Safety Code, the State of Wyoming Electrical Safety Division regulations and the City of Cody ordinances and codes. 1.03 Changes or Conflicts in Requirements and Guidelines The governmental codes and ordinances in Section 1.02 are the basis for some information in this booklet. It is the intent of these guidelines and requirements to follow all applicable codes, ordinances and regulations. If a conflict arises, the appropriate code, ordinance or regulation will supersede the interpretation offered in this booklet. These requirements are subject to change if the governing codes, ordinances or regulations change. The Utility does not assume the responsibility for keeping this booklet current. In case of doubt on the applicability of any item, one should consult the Utility. When this booklet uses the phrase “consult utility,” it shall mean for every installation, not a single contact. 1.04 Application for Service The Customer must provide the Utility with accurate load information and the requested service date as early as possible. Requests for service to commercial and industrial customers normally require 60 days planning by the Utility to serve the load. Installations requiring transformers or other equipment not in stock may require six months lead time or more. Consult the Utility for service dates for your installation. ---PAGE BREAK--- 4 Electric Distribution Standards City of Cody January 2012 For commercial, industrial or residential subdivisions, mobile home parks, and apartment complexes, the requests for service shall include a City Council approved plat. Such plans should show preferred service and meter locations and a single line diagram of the electrical layout. The request must show all load information, including lighting, receptacle, water heating, cooking, electric heat, air conditioning, and motor load. The Customer must provide sufficient information on equipment operations to establish the kilowatt demand of the load. The Utility has a staff available for advice on Distribution Standards and problems related to electric energy use for new, existing and reconstructed installations. The Customer and the Contractor are liable for any damage to Utility equipment or personal injury unless they give adequate notice to the Utility and receive approval from the Utility for the change or addition. When conditions arise during construction that requires changes in service arrangements, the Customer must consult with the Utility to negotiate satisfactory alternative arrangements. Communication with the Utility will afford you this service. 1.05 Types of Service Furnished Electric service available is 60-hertz, alternating current, single or three phase. Nominal secondary voltages available by overhead or underground distribution lines in the service area are as follows: • Single-phase, 120/240-volt, 3-wire, grounded • Three-phase, 208Y/120-volt, 4-wire, grounded wye • Three-phase, 480Y/277-volt, 4-wire, grounded wye Under certain conditions, the Utility will provide single phase, 120/208-volt, 3-wire grounded service, single-phase, 240/480-volt, 3-wire, grounded service, or three-phase, 240/120-volt, 4- wire, grounded delta service. Again under certain conditions, the Utility will supply primary delivery at the distribution voltage standard for the requested service location. All service provided by the Utility is subject to the terms and conditions specified in later sections of this manual. 1.06 Approval for Service City of Cody ordinances require a Customer to obtain a permit before the Utility provides service. In addition, State of Wyoming Statutes require that the electrical inspection authority (in this case the City of Cody Building Inspector) approve the installation before it is energized. ---PAGE BREAK--- 5 Electric Distribution Standards City of Cody January 2012 1.07 Permanent Service Connection Only authorized Utility employees shall make the permanent connection or disconnection of the Utility’s electric service to a building or structure. 10.03 Seals The purpose of seals placed by the Utility on meters and associated service equipment is to prevent injury or tampering. Under normal circumstances, only the Utility can remove seals. If an emergency requires seal removal before notification, the person responsible must notify the Utility as soon as possible. The Utility can then inspect the installation and replace the seal. Section II Services 2.01 General The location of the service entrance on the Customer’s premises is an important consideration to both the Customer and the Utility. The installer shall locate the service entrance to make the meter and service easily accessible from the Utility distribution lines (refer to the figures on pages 8 & 12). The service entrance shall be convenient for the installation, operation and maintenance of Utility meters and equipment. The Customer shall consult the Utility for designation of the point of attachment for overhead service drops, underground service laterals, preferred meter and service locations, required current transformers, and terminal cabinet enclosures. The Customer shall contact the Utility if variations from these designated locations are desired. For secondary voltage service at 200 amps or less, the Utility will provide, install and maintain meters and conductors defined in Article 100 of the National Electrical Code as service drop or service lateral. For new services, the utility will provide up to 125 feet of secondary conductor for either overhead service drops or underground service laterals. For services sized at greater than 200 amps, the Customer will provide, install and maintain all service equipment, including service laterals (conduits & conductors), switches, service entrance conductors, raceways, enclosures, and meter sockets, and will further provide right-of-way and space for the installation and maintenance of the Utility facilities. The point of attachment for service laterals will normally be the point at which Utility maintenance responsibilities end. For services of 200 amps or less, the point of attachment will be the line side of the meter socket. For services larger than 200 amps, the point of attachment is where the service lateral conductors connect to the Utility transformer or pedestal. The customer- ---PAGE BREAK--- 6 Electric Distribution Standards City of Cody January 2012 provided conductors that run into the transformer shall be cut three feet above the transformer secondary bushings to provide sufficient length for replacing transformers. Normally, service to a building will be through one set of main service conductors of the same voltage classification. The Utility may tap these main service conductors where more than one meter installation is necessary in a building of multiple occupancies. For either residential or commercial services, an outside disconnect must be provided for emergency situations. Where two or more meters are grouped, each meter position must be clearly and permanently marked by means of a metal or hard plastic engraved type label. Such marking will indicate the particular location or address that it supplies. Service will not be established until the marking is completed. Un-metered service wires and metered load wires will not be run in the same conduit, raceway or wire gutter. For overhead service masts, the minimum conduit size shall be 2” GRC conduit with an appropriate weather head. 2.02 Point of Delivery The point of delivery shall normally be the point of attachment as defined in section 2.01 above. The exact location of said point of delivery shall be at the Utility’s discretion. The Utility shall separately meter and bill any additional service to the same Customer at other points of delivery at a different voltage or phase classification. 2.03 Sealing of Cabinets and Gutters All cabinets and gutters containing unmetered conductors, other than mainline switches required by applicable electrical codes, must be arranged for sealing with the Utility’s seal. Removable conduit fittings may be installed between the service outlet and the meter when approved by the Utility. These fittings must be visible from the meter location or from an exterior ground position and must be arranged for sealing. 2.04 Power Quality Interference If it is determined that a customer’s equipment is causing interference, excessive harmonics or other power quality issues with the Utility’s system, it is the customer’s responsibility to diagnose and correct the problem. If the problem is not corrected in a timely manner, the Utility reserves the right to disconnect service to the customer until the power quality issue is corrected by the customer. ---PAGE BREAK--- 7 Electric Distribution Standards City of Cody January 2012 Section III Temporary Construction Distribution Standards 3.01 General Upon request, and with application, the City of Cody will supply temporary service at a location adjacent to the City’s facilities. Application for service and appropriate fees shall be paid at City Hall before said service will be given. An electrical permit is also required before hook up will be done. Always locate temporary services for construction work to protect the meter from accidental damage, and, when practical, in a location usable throughout the entire construction period. If several homes will be built from one temporary service that temporary service should be given the address of the last home to be built. If a temporary service must be moved, a new application is needed. 3.02 Requirements – Overhead: • To ensure strength, the pole or post must be at least butt treated and free from any visible defects. • The pole or timber shall be no less than 20 feet long planted 5 feet in the ground. More ground clearance may be required if service will cross traffic areas. • The ground rod shall be visible when inspection is made. • Guying may be required – consult City Engineer • Meter to be no more than 6’ from ground line with a main disconnect. 3.03 Requirements – Underground • Post must be long enough to be firmly planted in the ground. • Locate close to an existing pad mounted transformer or secondary pedestal with enough cable tails to extend inside said facilities. • Ground rod shall be visible when inspection is made. • Meter to be no more than 6’ from ground line with a main disconnect. 3.04 Meter Socket Requirements for Temporary Construction Services Temporary Construction Service Meter Socket Type Single phase, 120/240 V 200amps or less 4-Jaw Single phase, 120/208 V 200 amps or less 5-Jaw All other temporary services Consult the City of Cody ---PAGE BREAK--- 8 Electric Distribution Standards City of Cody January 2012 Section IV Residential Meter Installations 4.01 Residential Meter Socket location – overhead installation The City of Cody will determine the exact location of meters that do not meet the criteria established in this manual. If the customer is unsure whether the meter location is acceptable, the City of Cody should be contacted. It is highly recommended that the City be consulted prior to establishing the final meter socket location. If a location is chosen that does not meet City requirements without notifying the City, the customer will be responsible for the underground service lateral installation. The location of the service entrance on the customer’s premises is an important consideration. Distance and accessibility to the City’s existing facilities is an important factor to consider. Consult the City to determine the point of attachment for overhead service drops. In all cases, the minimum service mast riser conduit size shall be 2” GRC conduit. Install residential meter outdoors at a location acceptable to the City of Cody. Avoid installations near windows or exterior walls that are likely to be fenced in. Never install the meter over window wells, steps in stairways, or in other unsafe or inconvenient locations. Keep shrubs and landscaping form obstructing access to the meter. The figure on the next page shows where a residential meter socket should be located. Clearances shall meet appropriate codes. In general, overhead residential services shall meet the following requirements: • Service mast must be a minimum of 2” GRC conduit with an appropriate weather head. • An outside disconnect means must be provided. • The City must be consulted before determining the final meter socket location to insure that it is accessible from the nearest point of attachment to the City’s electrical system. • The meter socket must be located between 4’ and 6’ of finished grade. • The meter socket must be located a minimum of 3’ from a window (including egress windows) unless prior authorization is received from the City Electrical Engineer. ---PAGE BREAK--- 9 Electric Distribution Standards City of Cody January 2012 ---PAGE BREAK--- 10 Electric Distribution Standards City of Cody January 2012 Single Family Overhead Service Detail NOTE: 1.
