Storage
The breaker should be placed in service immediately in its
permanent location. However, if it must be stored for an
indefinite period, it should be carefully protected against
condensation, preferably by storage in a warm dry room.
The breaker should be stored in a clean location, free
from corrosive gases or fumes. In particular, protect the
breaker from moisture and cement dust, as that combina-
tion may be corrosive.
If the breaker is stored for any length of time, it should be
inspected periodically to ensure good mechanical condi-
tion.
1.3 Preparation for Installation
Check that the primary disconnect fingers are smooth and
free of nicks and burrs. If they are dry, apply a thin coat of
GE Lubricant D6A15A1 (MobilGrease 28, catalog number
193A1751P1) to the contact surfaces.
