When a breaker is ready for installation, a lifting harness in
conjunction with an overhead lift or portable floor lift can be used to
move a breaker, if this is preferable to rolling the breaker on the
floor using self contained wheels. If the breaker is to be lifted,
position the lifting device (lifting straps should have at least a 1600
pound capacity) over the breaker and insert the lifting harness
hooks into the breaker side openings and secure. Be sure the
hooks are firmly attached before lifting the breaker. Stand a safe
distance away from the breaker while lifting and moving.
3.3 STORAGE
If the circuit breaker is to be placed in storage, maximum protection
can be obtained by keeping it in the original shipping container.
Before placing it in storage, checks should be made to make sure
that the breaker is free from shipping damage and is in satisfactory
operating condition.
The breaker is shipped with its contacts open and closing springs
discharged. The indicators on the front panel should confirm this.
Insert the maintenance tool in the manual charge socket opening
(Figure 3-2). Charge the closing springs by pumping the handle up
and down about 36 times until a crisp metallic “click” is heard. This
indicates that the closing springs are charged and is shown by the
closing spring “charged” (yellow) indicator. Remove the mainte-
nance tool. Push the “manual close” button. The breaker will close
as shown by the breaker contacts “closed” (red) indicator. Push the
“manual trip” button. The breaker will trip as shown by the breaker
contacts “open” (green) indicator. After completing this initial check,
leave the closing springs “discharged” and breaker contacts
“open”.
Outdoor storage is NOT recommended. If unavoidable, the outdoor
location must be well drained and a temporary shelter from sun,
rain, snow, corrosive fumes, dust, dirt, falling objects, excessive
moisture, etc. must be provided. Containers should be arranged to
permit free circulation of air on all sides and temporary heaters
should be used to minimize condensation. Moisture can cause
rusting of metal parts and deterioration of high voltage insulation. A
heat level of approximately 400 watts for each 100 cubic feet of
volume is recommended with the heaters distributed uniformly
throughout the structure near the floor.
Indoor storage should be in a building with sufficient heat and
circulation to prevent condensation. If the building is not heated, the
same general rule for heat as for outdoor storage should be
applied.
