SECTION 3-Storage
It is recommended that the breaker be put into service
immediately in its permanent location. If this is not possi
ble, the following precautions must be taken to insure the
proper storage of the breaker:
1.
The breaker should be carefully protected against
condensation, preferably by storing it in a warm dry room,
since water absorption has an adverse effect on the insula
tion parts. Circuit breakers for outdoor switchgear should
be
stored in the equipment only when power is available
and the heaters are in operation to prevent condensation.
2.
The breaker should
be
stored in a clean location free
from corrosive gases or fumes. Particular care should
be
taken to protect the equipment from moisture and cement
dust, as this combination has a very corrosive effect on
many parts.
CAUTION:
IF THE BREAKER IS STORED FOR
ANY LENGTH OF TIME, IT SHOULD BE INSPECTED
PERIOD/CALLY TO SEE THA T RUSTING HAS NOT
STARTED AND TO ASSURE GOOD MECHANICAL
CONDITION. SHOULD THE BREAKER BE STORED
UNDER UNFAVORABLE ATMOSPHERIC CONDI
TIONS, IT SHOULD BE CLEANED AND DRIED OUT
BEFORE BEING PLACED IN SERVICE.

are interchangeable in their equipment
compartments:
drawout breakers of different frame sazes are not anter
changeable. To prevent inserting the wrong type breaker
into a drawout compartment. suitable "reJectaon hardware"
is affixed to each breaker and ats compartment. Fagure
