Electrical Operation of Closing
Solenoid Test

Refer to Figure 13 to assemble and connect the equip-
ment. The recloser head casting and the control must be
solidly grounded and in a test cage.

1.

With the yellow manual operating handle down to
LOCKOUT position, energize the high-voltage trans-
former.

2.

Using a hotstick, raise the yellow operating handle to
the CLOSED position. The recloser should close
immediately, indicating correct operation of the clos-
ing solenoid.
