Electrical Closing – Motor-Operated
Low-Voltage Closing Solenoid / Auxiliary-
Powered NOVA Reclosers
High-voltage is not required for reclosers utilizing a motor-
operated closing mechanism, low voltage closing, or
auxiliary-powered NOVA recloser. For information on
energizing the recloser, refer to the appropriate recloser
installation manual. Low voltage supply can use either 120
or 240 VAC for input power. Check the name plate on the
recloser to verify the correct closing power requirements.
Figure 47 shows a test circuit for motor-operated, low-
voltage solenoid-closing, and auxiliary-powered NOVA
reclosers. Since these reclosers require only a low voltage
source for closing, high-voltage transformer T3 and its
protective cage is eliminated. All other equipment is the
same as the test equipment shown in Figure 46.
Manual Closing – Solenoid-Operated
Reclosers
If high-voltage for operating the closing solenoid is not
available, manual closing can be substituted for electrical
closing. However, not all control settings can be checked
since manual closing is not synchronized with the closing
coil control circuit in the control.
Follow these steps to manually close the recloser:
1. Remove the closing tool port cover and gasket from
the side of the recloser head casting.
2. Insert the tee-handled tool (available as an accessory)
into the port, engaging the pin on the closing shaft
(Figure 48).
3. Close the recloser by placing the yellow operating
handle (located under the sleethood) into the up or
CLOSED position and turning the closing tool one-
quarter turn clockwise.
4. After each trip operation, about 1/2 second elapses
while the closing solenoid plunger is moving upward to
reset the main toggle latch.
5. After the main toggle latch resets, the recloser can be
closed again by operating the manual closing tool.
6. Replace the gasket and port cover on the recloser
head after testing has been completed.

WARNING: Explosion hazard. Excessive
Contact Arcing. Do not use the manual closing
tool to close an oil-insulated energized recloser. Closing
an energized oil-insulated recloser with a manual clos-
ing tool can cause excessive contact arcing, rapid
build-up of gas within the equipment, and possible
explosion which can cause death, severe personal
injury, and equipment damage. T203.2
CAUTION: Equipment damage. Do not turn the
manual closing tool more than one-quarter turn
clockwise. Forcing the tool beyond the mechanism stop
may shear the pin on the closing shaft of the recloser.
