Assembly and installation of switchgear
equipment
General requirements
Before assembling or installing the switchgear
equipment, all components should be available
at the site location. This will facilitate switchgear
component identification as well as installation.
The foundation should be prepared in accordance
with the instructions in the previous sub-sections,
and all embedded conduits installed and capped.
Notice:
If rollers are to be used for movement of
the equipment to its permanent installation, it is
recommended that the shipping skid not be
removed until the equipment is placed in position
over the anchor bolts.
If a transformer is not part of the installation,
and/or the equipment has been split for shipment,
place the center section on the foundation first.
Assemble the remaining sections outward from
the center section, in each direction. If the
switchgear equipment is part of a load center unit
substation, the transformer section should
be set on its pad first in accordance with the
instructions furnished with the transformer. All
remaining sections of the switchgear should then
be installed.
Notice:
Before assembling and installing
the switchgear equipment, the foundation must
be absolutely level and clear of debris to prevent
damage and possible misoperation of the
switchgear equipment.
Detailed assembly and installation
instructions indoor equipment
The recommended procedure for installation
of an indoor switchgear or load center unit
substation is as follows:
1. Position the equipment - Position the equipment
or sections of the complete equipment in their
final location.
1. Indoor Lifting Plates

Lifitng plate location
Notice:
If the equipment line-up was
split into shipping sections, the
lifting plates on corners of adjacent
sections shown in Figure 48 must be
removed. Failure to remove these
plates will interfere with mating
adjacent sections and prevent
installation of bus splice plates,
structure tie plates, etc.
Once the lifting plates have been removed, they
may be discarded.
Notice:
In the event the lifting plates
must be reassembled on the
equipment for lifting purposes, they
must be moved to locations where
unused screw holes are available,
generally achieved by shifting the
plate horizontally on the mounting
surface one bolthole from its
previous location. When remounting
the lifting plates, torque the
mounting bolts to 7-9 ft-lbs.
Notice:
All mating sections of the
equipment line-up (including
transformer, if applicable) must be
securely fastened together prior to
tightening anchor bolts fastening
the equipment to the mounting
surface.
