403. SINGLE SERVICE DROP
Only one service drop connected to the same overhead
mains will be attached to any one building, and only one set of
service
entrance conductors shall be connected to each service
drop except in cases specifically permitted by the NEC, Section
230.2, or where special permission has been obtained from the
“authority ha ving jurisdiction.” The drop may consist of parallel
service cables for capacity. Overhead services may be provided
up to a nd including 1000 Ampere total switch frame capacity
unless limited by construction problems. Overhead secondaries
shall be limited to two - four conductor (three phase and one
neutral / messenger) cables 336.4 kcm (or smaller). Where greater
capacity
is required, other types of construction such as
underground
service must be used. Refer to Section IX.
404. SERVICE/METER POLE
In lieu of running a regular service drop to a building, the
Company
may terminate its electric service conductors on a
customer
owned pole or structure suitably located on the
customer's
property. In such event, the customer shall furnish,
install,
own and maintain all facilities beyond this pole.
The Company requires the meter enclosure (and
recommends
the service disconnect) to be mounted on the
service/meter
pole. Although a disconnect and overcurrent device
(on the
pole) may not be required (by the NEC) for all
applications, it is highly recommended since it provides protection
for the customer’s cable and allows the customer
to disconnect
and m aintain
their conductors without the cost of a Company line
crew visit.
Note: Metered and unmetered wires are not allowed in
the same
conduit, raceway or gutter. A riser (only) pole is not
considered
to be a service/meter pole. Refer to Illustration No. 4
(single meter) or No. 5 (multiple meter) in Section
XII for
construction
details.
