SECTION 3: RECEIVING, HANDLING AND
STORAGE
Type VCP-WR circuit breakers are subjected to
complete factory production tests and inspection
before being packed. They are shipped in packages
designed to provide maximum protection to the
equipment during shipment and storage and at the
same time to provide convenient handling. The
optional maintenance tool is shipped separately.
3-1 RECEIVING
Until the breaker is ready to be used, DO NOT remove it
from its container. If the breaker is to be placed in
storage, maximum protection can be obtained by
keeping it packed as shipped.
Upon receipt of the equipment, inspect the containers
for any signs of damage or rough handling. Open the
containers carefully to avoid any damage to the con-
tents. Use a nail puller rather than a crow bar when
required. When opening the containers, be careful that
any loose items or hardware are not discarded with the
packing material. Check the contents of each package
against the packing list.
Examine the breaker for any signs of shipping damage
such as broken, missing or loose hardware, damaged or
deformed insulation and other components. File claims
immediately with the carrier if damage or loss is
detected and notify the nearest Cutler-Hammer Sales
Office.

3-2 HANDLING
WARNING
DO NOT USE ANY LIFTING DEVICE AS A PLAT-
FORM FOR PERFORMING MAINTENANCE, REPAIR
OR ADJUSTMENT OF THE BREAKER OR FOR
OPENING, CLOSING THE CONTACTS OR
CHARGING THE SPRINGS. THE BREAKER MAY
SLIP OR
FALL CAUSING SEVERE PERSONAL INJURY.
ALWAYS PERFORM MAINTENANCE, REPAIR AND
ADJUSTMENTS ON A WORKBENCH CAPABLE OF
SUPPORTING THE BREAKER.
Type VCP-WR breaker shipping containers are designed
to be handled either by use of a rope sling and overhead
lifting device or by a fork lift truck. If containers must be
skidded for any distance, it is preferable to use roller
conveyors or individual pipe rollers.
Once a breaker has been inspected for shipping dam-
age, it is best to return it to its original shipping container
until it is ready to be used.
When a breaker is ready for use, a lifting yoke in con-
junction with an overhead lifter or portable floor lifter can
be used to move a breaker. If the breaker is to be lifted,
position the lifting yoke over the breaker and insert
lifters into the breaker side openings with the lifting hole
toward the interrupters. Once the lifting yoke is securely
seated in the holes, the breaker can be carefully lifted
and moved.
3-3 STORAGE
If the circuit breaker is to be placed in storage, maxi-
mum protection can be obtained by keeping it packed as
shipped. Before placing it in storage, checks should be
made to make sure that the breaker is free from ship-
ping 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
3-7
)
.
Charge
the closing springs by pumping the handle up and down
approximately 38 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 maintenance 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
