Type DHP-VR 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. Accessories
such as the maintenance tool, levering crank, etc. are
shipped separately (Figure 3-1).

3-1 RECEIVING

Until the breaker is ready to be delivered to the
switchgear site for installation, DO NOT remove it from
the wooden crate. If the breaker is to be placed in
storage, maximum protection can be obtained by
keeping it in its crate.
Upon receipt of the equipment, inspect the crates for
any signs of damage or rough handling. Open the crates
carefully to avoid any damage to the contents. Use a
nail puller rather than a crow bar when required.
When opening the crates, 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

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 DHP-VR breaker shipping containers are designed
to be handled either by use of a rope sling and over-
head 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 crate
until it is ready to be installed in the Metal-Clad
Switchgear.
When a breaker is ready for installation, a lifting yoke, in
conjunction with an overhead lifter or portable floor lifter,
can be used to move a breaker. if this is preferable to
rolling the breaker on the floor using self contained
wheels. 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.
