Section 1 - Receiving, Handling and Storing
1.0 RECEIVING AND HANDLING
The circuit breakers may be shipped completely assem-
bled and inside their respective compartments.
Receiving and handling
of
this equipment is covered
in
Cutler-Hammer Instruction Book 32-690 for Low-Voltage
Metal-Enclosed Switchgear, Types DS and DSO.
If
the circuit breakers are not shipped
in
the switchgear
assembly, they will be packed separately
in
individual
cartons
or
crates. These packages must be handled with
care to avoid hidden damage to the circuit breakers.
If
the circuit breakers have been shipped
in
the switch-
gear assembly, proceed as described
in
Section
2.
If
the
breakers have been shipped
in
separate packages, re-
move them from the crate
or
carton carefully so as not to
cause damage. Place the breakers
on
the switchgear
extension rails. (See Section 2.3 before attempting to lift
breakers.) Remove the insulating barriers and arc chutes.
Inspect the contact structures to be sure no damage has
occurred during shipment. Replace the arc chutes and
insulating barriers and proceed as described
in
Section
3.
1.1
STORING
If
it is necessary to store the equipment before installa-
tion, keep it
in
a clean dry place, protected from dirt and
water and with ample air circulation and heat,
if
neces-
sary, to prevent condensation. Like all electrical appara-
tus, these units contain insulation. Although it is
of
highest quality,
it,
like all other insulation, must be pro-
tected against dirt and moisture. Refer to Instruction
Book 32-690-C for details.
Note: Breakers that have been stored or have infre-
quent operations shall be operated a minimum
of
five
times before being placed
in
service.
1.2 WEIGHTS: CIRCUIT BREAKERS AND FUSE
TRUCKS
Table 3 gives the approximate weights
of
DS and DSL
circuit breakers. They will vary slightly due to the differ-
ences
in
functional components
of
the individual DS
Breaker, and the size
of
the current limiters supplied
on
DSL Breakers. Fuse truck weights will vary due to differ-
ences
of
fuse sizes.
