Section 2 Installation
allows the utility to remove the meter without
having to detach any cables. The meter socket
is contained inside the meter enclosure, which
is the box that attaches to the service conduit.
The meter socket and enclosure are usually sold
together and referred to as a meter socket. See
Figure 10-15.
Service conductors enter the enclosure and
are secured to the line-side lugs of the socket.
Note that the neutral conductor is always
connected to the center contact and continues
essentially uninterrupted through the meter
socket on its journey to the service main discon-
nect or panel. The meter itself will be installed
by the utility when the service drop or lateral
is completed.
