“connected to the grounded service conductor (neutral)” per
NEC Section 250.24(A). The enclosure itself shall not be part of
the grounding electrode conductor per NEC Sections 250.62 and
250.64.
For underground residential service installations, meter
sockets for use with # 4/0 or larger service cable shall
be of the
"side-wired" (or otherwise wired out away from the meter line
side terminals) underground type. For non-residential
underground
application and for “continuous conduit systems,”
the "side-wired" socket is not required; however, it is highly
recommended since the meter socket base is less likely to be
damaged by frost action. Refer to the "Supplement" for meter
socket requirements and options (see inside back cover of this
handbook).
B. METER BY-PASS REQUIREMENTS
A Residential* 100, 125, 150 or 200 amp socket does not
require a bypass; however, a single handle lever operated by- pass
is permitted. Since it allows for testing and changing-out
of the
meter without interrupting service, a lever operated by-pass is
recommended wherever minimization of possible interruption
of
service, during normal business hours is important, such as
in the
case o f a home office or certain community/house loads.
A single hand lever operated by-pass is highly
recommended for residential
locations with pump operated
septic/ s ewer systems.
