CUTLER-HAMMER 24kV Type W-VAC Circuit Breaker

SECTION 3: RECEIVING, HANDLING AND STORAGE

3-1 GENERAL

Type W-VAC Vacuum Circuit Breakers are

subjected to complete factory production tests in

accordance with IEC 56 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 and accessories, such as maintenance tool,

are shipped separately.

3-2 RECEIVING

If the circuit breaker 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 contents. 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 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 office.

Effective 12/98

3-3 HANDLING

DO NOT USE ANY LIFTING DEVICE AS A

PLATFORM FOR PERFORMING

MAINTENANCE, REPAIR OR ADJUSTMENT

OF THE CIRCUIT BREAKER OR FOR

OPENING, CLOSING THE CONTACTS OR

CHARGING THE SPRINGS. THE CIRCUIT

BREAKER MAY SLIP OR FALL CAUSING

SEVERE PERSONAL INJURY. ALWAYS

PERFORM MAINTENANCE, REPAIR AND

ADJUSTMENTS ON A SOLID WORK

SURFACE CAPABLE OF SUPPORTING THE

CIRCUIT BREAKER.

When the circuit breaker is ready for installation,

a lifting yoke in conjunction with an overhead lifter

or portable floor lifter can be used to move a

circuit breaker. When a circuit breaker is to be

lifted, position the lifting yoke over the circuit

breaker and insert the lifters into the circuit

breaker side openings with the lifting hole toward

the interrupters. Once the lifting yoke is securely

seated in the holes, the circuit breaker can be

carefully lifted and moved.
