SECTION 2: SAFE PRACTICES
The circuit breakers are equipped with linear actuator
operating mechanisms. They are designed with built-in
safety interlocks to provide for safe operation. In
addition, other optional interlocks are available
depending upon the application. Refer to Section 5 for
additional interlock information. It is the customers'
responsibility to insure that appropriate interfaces with
the breakers are provided and tests conducted to
adequately prove proper installation and functioning.
WARNING
TO PROTECT THE PERSONNEL ASSOCIATED WITH
INSTALLATION, OPERATION, AND MAINTENANCE
OF THESE BREAKERS, THE FOLLOWING
PRACTICES MUST BE FOLLOWED:
Only qualified persons, as defined in the Local
Electrical Codes, who are familiar with the
installation and maintenance of medium voltage
circuits and equipment, should be permitted to work
on these breakers.
Read these instructions carefully before attempting
any installation, operation or maintenance of these
breakers.
Always remove drawout type breakers from their
enclosure before performing any maintenance.
Failure to do so could result in electrical shock
leading to death, severe personal injury and/or
property damage.
Always make sure that primary and secondary
power is disconnected from a fixed breaker before
performing any maintenance. Failure to do so could
result in electrical shock leading to death, severe
personal injury and/or property damage.
Do not work on a closed breaker or a breaker with
closing springs charged. The closing springs should
be discharged and the main contacts open before
working on the breaker. Failure to do so could
result in cutting or crushing injuries.
Do not use a circuit breaker by itself as the sole
means of isolating a high voltage circuit. As
appropriate, use an isolation means and follow all
lock-out and tagging rules of the Local Electrical
Codes and any and all applicable codes,
regulations and work rules.
Always ensure that drawout circuit breakers are in
one of their designed cell positions, such as
Connect, Test/Disconnect or Remove. A circuit
breaker permitted to remain in an intermediate
position could result in control circuits being
improperly connected resulting in electrical failures.
Breakers are equipped with safety interlocks. Do
not defeat them. This may result in death, bodily
injury and/or equipment damage.
Do not work on a circuit breaker while suspended
from a lifting means. Maintenance work should be
performed on a properly supported cart or table.

SECTION 3: RECEIVING, HANDLING AND
STORAGE
VCP-TL and VCP-TRL 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.
3-1 RECEIVING
Until the breaker is ready for use, it is best NOT to
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 from rough handling and/or
external damage incurred during the transportation
phase. Record any observed damage for reporting to
the transportation carrier and EATON. All reports should
be as specific as possible and include the order number
and other applicable nameplate information.
Every effort is made to ensure that circuit breakers
arrive at their destination undamaged and ready for
installation. Care should be exercised, however, to
protect the breakers from impact at all times. Do not
remove protective packaging until the circuit breakers
are ready for inspection, testing and/or installation.
3-2 HANDLING
WARNING
DO NOT USE ANY LIFTING DEVICE AS A PLAT-
FORM FOR PERFORMING MAINTENANCE, REPAIR
OR ADJUSTMENT OF THE BREAKER, FOR
OPENING OR 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 SUP-PORTING THE BREAKER.
Shipping containers are designed to be handled either
by use of a sufficiently strong 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.
3-2.1 UNPACKING
Before beginning to unpack new circuit breakers, read
and understand the directions. Unpacking a fixed circuit
breaker is described in the next paragraph in detail.
Unpacking a drawout circuit breaker is also simple to
accomplish and is not described here in detail. Just
proceed by carefully removing all packing material used
for protection during shipment and the fasteners used to
secure the drawout circuit breaker to its shipping pallet.
When ready to inspect and install the circuit breaker,
carefully remove any banding straps and lift off the card-
board box. Remove any additional packing material and
internally packed documentation. The circuit breaker is
mounted to a wooden shipping pallet. A keyed metal
clamp is used on each side of the circuit breaker to hold it
to the wooden pallet (Figure 3-1). Remove the screws
from the wooden pallet on each side and lift up and out
on the keyed metal clamps for removal (Figure 3-2). The
circuit breaker is now ready to be removed from its ship-
ping pallet. Save all shipping hardware and packaging
material for any future shipments of the circuit breaker.
3-2.2 LIFTING
To closely examine, install or just become familiar with
the circuit breaker, carefully lift and place the circuit
breaker on a solid work surface capable of handling the
circuit breaker's weight (Table 3.1). The circuit breaker
is provided with two integrally mounted lifting hooks for
use with a standard sling (Figure 3-1). Once the sling is
properly placed, the breaker can be carefully lifted and
moved using an overhead lifter or portable floor lifter.
Every effort should be made to minimize circuit breaker
swing or tilt.

WARNING
THE CUSTOMER SHOULD READ AND UNDER-
STAND THE MATERIAL PRESENTED AND ANY
WARNINGS OR CAUTIONS OFFERED IN THE
INSTRUCTION BOOK BEFORE ANY ATTEMPT IS
MADE TO INTERFACE WITH THIS CIRCUIT BREAK-
ER.
IT IS IMPERATIVE THAT ALL APPLICABLE ANSI
STANDARDS BE COMPLIED WITH IN EVERY
RESPECT AND THAT NO COMPROMISES ARE MADE
WITH RESPECT TO THE ANSI GUIDELINES OR
INTENT.
UNDER NO CIRCUMSTANCES SHOULD
ALTERATIONS BE MADE TO EATON SUPPLIED VCP-
T VCP-TR CIRCUIT BREAKERS UNLESS THE
ALTERATION IS SPECIFICALLY ADDRESSED IN AND
PERMITTED BY THIS INSTRUCTION BOOK.
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.
Outdoor storage is NOT recommended. If unavoidable,
the outdoor location must be well drained and a tempo-
rary 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.
