406 POINT OF ATTACHMENT
406.1 Provisions: A solid Point of Attachment for supporting the Service Drop on the
building shall be provided by the Customer at a point which will comply with the
provisions of ARTICLE 402. The Point of Attachment shall not be more than
25 feet above ground, unless a greater height is required for proper clearance
(See Illustration 1 - Arrangement of Overhead Service Equipment, page 20).
Company personnel will specify on the Service Outlet Location, the height of the
Point of Attachment if it must be less than the minimum or greater than 25 ft.
above grade.
406.2 Clearances: Where the required heights and clearances specified above cannot be
maintained, the Customer shall provide an extension support, which is of a
permanent nature and of sufficient strength to support the Service Drop at the
required minimum clearance. In such cases, the Customer's Service Outlet is to be
located above the service support at a height which will permit the required
clearances. A typical service mast installation is shown in Illustration 2 - Typical
Residential Service Mast, on page 19. In such an installation, 2" or larger
galvanized iron conduit, 2" or larger intermediate metal conduit, or 3" or larger
rigid aluminum conduit shall be used. If a Service Mast will not have sufficient
strength to properly support the Service Drop, installation of a service bracket will
be required.
