Where danger of plow or traffic damage exists, barriers
consisting of concrete filled 6 inch IPS steel posts set 4 feet deep
must be provided for protection (Pressure treated 6 x 6 inch
(minimum) timber posts
may be substituted in residential areas).
The protective posts shall be located so as not to interfere with
opening the doors or restrict access to the transformer cabinet.
Generally
the posts will be located near the corners of the
padmount transformer.
Minimum clearances to buildings and other obstructions
(including trees, shrubs and fences) shall be 3 feet from the rear, 5
feet
from the sides, and 10 feet from the front of the transformer
pad. There shall be no openings in the building wall in back of,
beside, or over the transformer, unless the transformer is a
minimum of 10 feet from the building. Side clearances from
doors or windows shall not be less than 10 feet. There shall
be a
minimum of 10 feet between the transformer and any gas
meter/regulator, gas relief valve, gas vent discharge, gas filling
connection,
or propane tank. Some insurance companies may
require increased clearances.
Transformers are to be located far enough away from
building overhang so that they will not be subject to damage by
falling ice and snow.
When padmount transformers are not installed immediately
upon the installation of the cable in the transformer pad, the
customer/developer
shall provide and install a Company approved
concrete,
steel or fiberglass cover over the pad opening to
eliminate exposure of the cable.
