SECTION 3: RECEIVING, HANDLING
AND STORAGE
3-1 GENERAL
Type VCP-W Vacuum Circuit Breaker Elements 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. Tools, such
as the maintenance tool, are shipped separately
3-2 RECEIVING
If the circuit breaker element is not to be used
immediately but 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 to
save any loose items or hardware that may be
otherwise discarded with the packing material. Check
the contents of each package against the packing list.
Examine the circuit breaker element 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
Eaton Office.
3-3
HANDLING
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 CIRCUIT
BREAKER ELEMENT MAY SLIP OR FALL CAUSING
SEVERE PERSONAL INJURY. ALWAYS PERFORM
MAINTENANCE, REPAIR AND ADJUSTMENTS ON
A SOLID WORK SURFACE CAPABLE OF
SUPPORTING THE BREAKER ELEMENT.

CAUTION
When a breaker element is ready for installation, a lifting
yoke in conjunction with an overhead lifter or portable
floor lifter can be used to move a breaker element.
When a breaker element is to be lifted, position the
lifting yoke over the breaker element and insert lifters
into the breaker element side openings with the lifting
hole toward the interrupters. Once the lifting yoke is
securely seated in the holes, the breaker element can
be carefully lifted and moved.
3-4 STORAGE
If the circuit breaker element is to be placed in storage,
maximum 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 element
is free from shipping damage and is in satisfactory
operating condition.
The circuit breaker element 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 3-3). 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. Operate the push-to-close button. The breaker
element will close as shown by the breaker contacts
"closed" (red) indicator. Operate the push-to-open but-
ton. The breaker element 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 of the breaker element is NOT
recommended. If unavoidable, the outdoor location must
be well drained and a temporary shelter from sun, rain,
snow, corrosive fumes, dirt, falling objects and
excessive moisture 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 air circulation to prevent condensation. If the
building is not heated, the same general rule for heat as
for outdoor storage should be applied.
