2011 Electric Service Requirements, 2 nd Edition
Section 7
7.8 Overhead Service
7.8.1 General
Overhead service can be provided to the customer from an overhead distribution system.
For a customer near an overhead line, the Power Company will install a service drop from
the Power Company’s line to the attachment point on the customer’s building. The Power
Company will install the appropriate size service conductor from its distribution line to the
service point. The customer shall obtain an easement for Power Company-installed
services that cross adjacent property. (The Power Company will provide the customer with
the easement form, and will record the executed easement.)
The Power Company owns and maintains the overhead service lateral from its distribution
line to the connection point at the weatherhead. The Power Company also owns and
maintains the meter. The customer owns the meter socket, the meter base, all wiring from
the meter socket to the service point, and all wiring beyond the meter socket.
Consult a Power Company representative for meter location not within the specifications
of this manual. The following is a partial list of exceptions in which the installations shall
be coordinated with the Power Company prior to installation:
1. The service runs over a road or street.
2. The service runs over or along an alley, a parking lot, or a non-residential driveway.
3. The service runs over an area traveled by agricultural equipment.
4. The service runs over exceptionally uneven ground.
5. A service of 480Y/277V.
Installation requirements for overhead service are listed below. These requirements are in
addition to the general requirements given in Section 7.6. For requirements relating to
specific overhead installation configurations, see Sections 7.8.2, Overhead Service to
Wall-Mounted Meters, and 7.8.3, Overhead Service to Meters Mounted on Poles.
Requirements:
1. A 24-inch conductor lead shall be provided for attachment to the service conductor.
2. The unmetered service conductor and the metered service conductor shall not be run
in the same conduit, raceway, or gutter.
3. Some installations require guying. Sections 7.8.2 and 7.8.3 detail guying criteria for
specific meter locations. Guying requirements are given in Section 7.8.4, Mast
Guying and Anchoring for Overhead Services.
4. If the service length is greater than the values in Table 7.8.2 (for wall-mounted
meters) or Table 7.8.3 (for meters mounted on poles), the Power Company shall be
consulted before the mast is installed.
5. The service entrance mast shall meet the requirements of NEC, state, and/or local
codes. Additionally, if the mast has service cable attached to it, the mast shall be
RMC or IMC. (Use of IMC as a mast requires prior approval by the local inspecting
agency, and shall not be used in coastal or contaminated areas).
6. The conduit and weatherhead shall be directly above the meter base, and conduit
material shall be uniform from the weatherhead to the meter base.
7. For service minimum heights, see the NESC clearances listed in Table 5.2.1.
This manual shall be distributed and interpreted in its entirety. Individual pages will not represent all the requirements necessary for an installation.
