04.10 SERVICE ENTRANCE - OVERHEAD
In general, only one (1) service drop will be installed by the Company to serve a building. The Company must always be consulted regarding the location of the service entrance and meter. The customer's service entrance may consist of an approved service cable, wires enclosed in approved conduit, or bus duct. All fittings used in the service entrance must provide a watertight connection. Duxseal or similar compound shall be used to seal service cables at outside meter boxes. Conduit joints shall be sealed by approved means. An approved service head is required for the service entrance. At least two (2) feet of wire must be left for the connection to the service drop of all services. (See figures in Requirements 12.04, 12.06 and 12.08).
If the second service is permitted based on the exceptions listed below from Article 230-2 of the National Electrical Code, a "permanent plaque or directory shall be installed at each service drop or lateral, or at each service equipment location, denoting all other services on or in the building or structure, and the area served by each".
|
For Fire Pumps where a separate service is required. |
|
For Emergency, legally required standby, optional standby, or parallel power production systems where a separate service is required. |
|
Multiple-Occupancy Buildings. By special permission, in multiple-occupancy buildings where there is no available space for service equipment accessible to all the occupants. |
|
Capacity Requirements. Two or more services shall be permitted: |
|
|
|
|
|
|
|
Buildings of Large Area. By special permission, for a single building or other structure sufficiently large to make two or more services necessary. |
|
For different characteristics, such as for different voltages or phases, or for different uses, such as for different rate schedules. |
|
For the purpose of Section 230-40, Exception #2, only, underground sets of conductors, size 1/0 and larger, running to the same location and connected together at their supply end but not connected together at their load end shall be considered to be one service lateral. |
The point of attachment of the service drop to the building must be such that the "drip loop" shall not be less than 10.5 feet above ground. Also, the point of attachment must be located to allow the Company to comply with the following National Electrical Safety Code clearance requirements. The attachment should not be more than 24 feet above ground unless a greater height is necessary for proper clearances.
A. 12 feet above sidewalks and spaces or ways accessible to pedestrians only.
B. 16 feet above roads, streets, alleys, residential and nonresidential driveways, parking lots, and other areas subject to truck traffic. (18 feet over PennDot roads).
C 2 feet above communication lines at any point of crossing, and 1 foot at the point of attachment to the building.
D. 3 feet between multiplexed service drop conductors (attached to buildings) and windows, doors, porches, and fire escapes.
E. 5 feet between multiplexed service drop conductors adjacent to windows, awnings, fire escapes, and other building projections (i.e. not attached to building).
F. 3.5 feet between multiplexed service drop conductors and roof or projections not accessible to pedestrians.
G. 27 feet over railroad tracks (permission/right-of-way required by railroad).
H. 4 feet over street railway wire facilities
The following parts of swimming pools shall not be placed under existing service conductors or any other open overhead wiring; nor shall such wiring be installed above the following:
(Minimum clearance from edge of pool or surface of water shall be 25 feet in any direction (up to 15,000 Volts)).A. Swimming pool and the area extending 10 feet horizontally from inside of the walls of the pool.
B. Diving structure, observation stands, towers or platforms. (Minimum clearance from these structures shall be 17 feet in any direction (up to 15,000 Volts)).
Refer to National Electrical Code 680-8.
When necessary to have the service cross a highway or street, and the height of service attachment does not permit proper clearance, the Customer shall install a riser or extension above the roof in accordance with specifications show in figures in Requirements 12.10 and 12.12.
Where service wires are to be attached directly on a building (i.e., not to a service mast protruding above the roof), the Customer will furnish a suitable device to be installed by the Customer/Contractor, for securing the service. It should be noted that "service knobs" are not acceptable. For service attachments the Customer will furnish a 5/8 inch bolt, which is to be installed by the Customer/Contractor. If installation of a bolt is not practical, as in the case of a modular home, the Customer/Contractor can furnish an equivalent device, such as an eye lag bolt, of equal strength.
All overhead service locations (both new and upgraded/relocated) must be approved by the appropriate Customer Operations Center prior to service equipment installation. Service equipment installed without approval and incorrectly located, will be subject to change or relocation. The point of attachment will normally be at the corner of the building nearest to the pole designated by the Company for the service connection. Services shall not cross over adjacent private property. (See figure in Requirement 12.02).
Overhead secondary service will not be furnished to serve new boat launch ramp areas designated for rigging and launching sailboats, including lighting for adjacent parking facilities or any associated staging areas into which sailboats may be towed. Service for such areas shall be furnished underground.
