duty cycle into an equivalent duty cycle based on the
actual operating duty of the recloser.
If the recloser has not completed an equivalent duty
cycle within ten years, an inspection must be made and
any needed maintenance performed. Refer to

on the recloser data plate are correct for the planned
testing.
2. Test electrical open and close operation. Close and
open the recloser contacts using the microprocessor
control. Confirm that the contacts have closed and
opened by:
A. The OPEN/CLOSE contact position indicator, or
B. By a continuity check between the recloser
terminals.
3. Test manual open, see Figures 14 and 15. Confirm that
the contacts have opened by:
A. The OPEN/CLOSE contact position indicator, or
B. By a continuity check between the recloser
terminals
C. A simple non-electric test of recloser operation
will assure that the operator mechanism and
the recloser linkage are functioning properly. The
following procedure may be used prior to high
voltage connection:
i. If the recloser is connected to a 120 or 240 Vac
power supply, pull out the fused disconnect
switch to prevent the spring charging motor from
running.
ii. Make sure the electronic control is in the
CONTROL LOCKOUT state.
