Heavy weight with a high center of gravity.
Can cause death, serious injury or property
damage.
Observe all handling instructions in this
instruction manual to prevent tipping or
dropping of equipment.
Lifting and Moving
There are a number of methods that can be used in han-
dling the breaker, which when properly employed, will not
damage the breaker. The handling method used will be
determined by conditions and available equipment at the
installation site. Refer to the breaker nameplate for the
weight. Lifting with a crane by the use of sling and lifting
lugs is the preferred method of handling; however, over-
head obstructions often dictate the method to be used. Fork
lift trucks may be used prior to removal of wooden skids.
Be sure that the forklift blades pass completely under the
breaker.
Refer to Figure 2 for lifting of the breaker using a sling.
Each power circuit breaker has provisions for attaching lift-
ing cables. Lifting lugs are provided on each side of the
breaker, which are designed for use with a sling or hooks
of the proper size and a crane of adequate height and ca-
pacity. Refer to the breaker nameplate for the weight.
Lifting Power Circuit Breaker with Crane
Recommended lifting of power circuit breakers
is by means
of cables connected to an overhead crane. The cables are
connected to the lifting lugs on the top of the breaker as
illustrated in Figure 2. A crane with sufficient height should
be used so the load angle (from horizontal) on the lifting
cable will be at least 63 degrees, when viewed from the
front or the rear. The minimum recommended cable length
to achieve proper load angle is 134 inches hook end to hook
end. A lesser angle (shorter cable) could cause damage to
the equipment.
Receiving, Handling & Storage
Storage
When it is necessary to store a power circuit breaker in an
area exposed to the weather or under humid conditions,
energize the space heaters provided and make certain that
any vents are uncovered to allow air to circulate. If at all
possible, install the breaker at the permanent location even
though it may be some time before the equipment is used.
It is also recommended that the breaker receive periodic
inspection during storage.
Access to the heater circuit is gained by opening the door
to the instrument panel compartment. Refer to wiring dia-
gram drawing for space heater circuit connections. Lubri-
cate hinges and other moving parts.
