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