Bid Package 08 North Well Field - Garney Construction

electric service conductors from a Company designated point of delivery outside of
the building (either secondary transformer terminals or service enclosure) to the
metering equipment location. See Figure 5-A for typical point of delivery (P.O.D.)
locations. Metering equipment locations other than outside the building are nonstandard
and require Company approval prior to installation of the meter.
Meterbases and transockets are not to be installed on Company poles. This
applies to both overhead and underground services.
500.05 Meter Work Space
Sufficient space in front of, above, below and on each side of meter sockets,
service enclosures, meterpacks and transockets is necessary for work space for
connecting and the reading of meters. No obstruction shall be within four feet in
front of the meter. See NEC Article 110.26 for working spaces.
500.06 Meter Sockets
The Customer will provide, install, and maintain self contained meter sockets.
Transockets, when required, will be provided by Company and installed and
maintained by Customer. These sockets are to be used exclusively for metering.
The Company reserves the right to refuse service if the incorrect socket is installed
or if the socket is not wired correctly. Each connector provided in the meter
socket is rated for a single aluminum or copper conductor. The number of
Customer conductors shall not exceed the number of connectors (shall not
double lug). See Figure 5-B, pages 46-50. Aluminum conductors require wire
brushing to remove oxide film and an application of oxide inhibitor immediately
before installation.
500.06.01 Meter Socket Ratings
Meter sockets are specified by their continuous current rating and are designed
for short term (three hours or less) overloads of 125%. Electrical panels are
specified by their maximum rating and any continuous loads (three hours or
more) are limited to 80% of this maximum. A 320 ampere meter socket has a
continuous rating of 320 amperes and a maximum rating of 400 amperes. A
400 ampere panel has a maximum rating of 400 amperes and a continuous
rating of 320 amperes. Even though these two items are referred to by different
numbers, their capabilities are identical and a 320 ampere socket is adequate
to serve a 400 ampere panel.
500.06.02 Ganged Meter Socket Assemblies
Ganged meter socket assemblies are for multi-family residential installations
and are 120/240 volt, three wire, single phase. Each of the ganged meter
socket assemblies must be clearly and permanently marked to indicate each
location to be served prior to the connection of service. See Figures 5-B,
pages 46-50 and 5-E, page 56 for typical dimensions, examples of layouts, and
terminal configurations.
