3-1 GENERAL
Type VCP-WL 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.
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
CAUTION
DO NOT USE ANY LIFTING DEVICE AS A PLATFORM
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.
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 the lifter tabs 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 capacitor bank discharged. The indicators on the
front panel should confirm this.
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.
3-5 TOOLS AND ACCESSORIES
Tools and accessories, both standard and optional are
available for use with the circuit breaker element
