Installation
e. Slowly open the switch. As the blade moves
in the opening direction, the blade shunt
contact must firmly engage the interrupter
housing contact before the blade disengages
from the jaw contact. Bend and reform the
shunt contact if necessary to attain the
proper contact.
f. Slowly close the switch. At the start of
the closing stroke, the interrupter housing
should be at the distance checked in Step
24 c) and should continue to make contact
with the shunt contact during the duration
of the closing stroke. This will ensure that
the shunt contact and interrupter housing
contact stay in the circuit long enough for
the interrupter to break the circuit during
the opening stroke.
g. If adjustment is required, loosen the bolts
that fasten the jaw-contact casting to its insu-
lator and slightly rotate the casting in order to
achieve the necessary clearances. Retighten
the bolts, making sure that the blade engages
the stationary contact on-center.
