Receiving
Equipment Packaging
Every package leaving the factory is plainly marked with the
case number, requisition number, and customer's order
number. If the equipment has been split for shipment, the
section numbers of the equipment enclosed in each shipping
package are identified.
NOTICE: To avoid the loss of any parts when unpacking,
the contents of each container should be carefully checked
against the packing list before discarding the packing
material.
The contents of each shipping package are listed on the
Master Packing List. In addition, this list includes the number
of the shipping crate in which miscellaneous parts needed to
install and operate the equipment (such as hardware, contact
lubricant, touch-up paint, breaker closing devices, etc.) are
located. Normally, such devices are packed in a cardboard
carton and the carton secured in an empty switchgear
compartment (Figure 2.1). If such items are packed in a
switchgear section instead of a separate crate, the list will
indicate the appropriate section number in which they are
stored. Large items (such as breaker lifting devices and
dollies used with indoor equipment) will always be shipped in
separate crates or cartons (Figure 2.2 and Figure 2.3).
Inspecting for Damage
All equipment leaving the factory is carefully inspected and
packed by personnel experienced in the proper handling and
packing of electrical equipment. Upon receipt of any
equipment, immediately perform a visual inspection to
ascertain if any damage has been sustained in shipping or if
there are any loose parts.
Circuit breakers may be shipped separately in individual
containers with the breaker in the open position. Circuit
breakers should be unpacked and visually inspected for
damage or loose parts as soon as possible after they have
been received.
Be sure to inspect all devices mounted or packed inside
compartments of each section to see if any have been
dislodged or damaged.
Filing a Claim
If any damage is evident, or indication of rough handling is
visible, file a claim for damage at once with the transportation
company and notify the nearest General Electric Company
Sales Office immediately. Information on damaged parts,
part number, case number, requisition number, etc., should
accompany the claim.

Handling
NOTICE: It is preferable to leave the shipping skids in place
under the switchgear until it reaches its final location. The
equipment should be installed in its final location prior to
installing the circuit breakers.
Indoor Enclosure Lifting
The indoor switchgear sections are best handled by lifting
with a crane (Figure 2.4). Removable lifting plates are
provided, as standard equipment, on the top of each
switchgear section. To preserve the external appearance of
the equipment, it is suggested that the lifting plates be left in
place except where adjacent equipment must be bolted
together, i.e. shipping splits, etc.
Utilize four equal length cables and an overhead crane, each
with a minimum load rating of twice the weight of the
switchgear.
Estimated weights for shipping splits appear on the Front
View drawings.
Example: Switchgear Section Weight = 5,000 pounds. The
crane and the four lift cables must have a minimum load
lifting capacity of 10,000 pounds.
WARNING: The angle between the cables and the top
of the equipment must be at least 45 degrees. If this is not
possible because of lack of headspace, spreader bars must
be used. Also, lift cables with greater load capability may
be necessary, depending upon the angle between the
cables and the crane hook.
Connect a cable from the crane to the four lifting plates
located on the top-front and rear of the switchgear (Figure
2.4).
Take up the slack in the lifting device very carefully and
manually stabilize the switchgear to prevent it from rotating.
DANGER: Do not stand under switchgear while it is
being moved. Serious injury may occur if the cables or
lifting device fail.
CAUTION: Gently lower the switchgear section onto the
level site location. If the switchgear is roughly handled or
jarred, it is possible to damage or misalign internal
components.
WARNING: Be sure to remove all circuit breakers from
their compartments prior to lifting. Failure to remove the
circuit breakers prior to lifting will result in a center of
gravity toward the front of the switchgear assembly and
may require additional rigging and stabilization.

Rollers
If crane facilities are not available, the equipment may be
moved into position by means of construction rollers placed
under the shipping skids. The switchgear may be raised
enough for the placement of rollers by means of a forklift.
There should never be less than four rollers under the
equipment unless the lineup is less than five feet long. Use
one roller for each 18 inches of equipment length.
Forklifts
When using a forklift to raise the lineup to position rollers
underneath, proceed as follows:
1. Expand forklift tines to their maximum (widest)
extension.
2. Carefully insert tines of forklift below one side of the
switchgear lineup at the approximate center of the
panel. Raise equipment and position one roller under
the skids close to the raised end of the lineup (Figure
2.5).
3. Carefully lower the gear until it rests on the roller
(Figure 2.6).
4. Repeat the lifting process at the other end and place
the appropriate number of rollers under the skids
spacing them evenly across the width of the lineup
(Figure 2.7).
5. Carefully lower the gear until it rests on the roller
(Figure 2.6).
6. While carefully pushing the switchgear to its final site
position, the rollers that are freed from the rear of the
switchgear are then repositioned at the forward end.
This procedure should be continued until the
switchgear is in its final location (Figure 2.7).
7. When the switchgear is in its final position, remove all
lug bolts holding the shipping skids to the switchgear
lineup.
8. Insert the tines of the forklift at one end of the lineup,
raise slightly, and remove the loose rollers.
9. Lower the end of the gear carefully to the floor.
10. Raise the other end of the lineup slightly and remove
the remaining roller at that end.
CAUTION: Do not attempt to lift or move the equipment
with a forklift positioned in the front or rear of the
equipment. It is possible to damage internal components
and/or the shipping skid.
NOTICE: If the shipping skids are removed prior to final
placement of the equipment, rollers may only be used to
move the equipment in a direction parallel to the front.
