What to do if the motor does not run to close the Southern States Circuit Switcher?
- E
  Emma JohnsonAug 5, 2025
  If the motor doesn't run when closing the circuit switcher, it could be due to several reasons. First, the latch check switch might be sensing a discharged shunt trip unit; in this case, hand crank close about five turns while observing the red band indicators on the shunt trip housing. Second, there might be insufficient shunt trip gap in the full open position; adjust the charging bolt to provide the required gap. Finally, the trigger and/or main trip latch in the shunt trip could be sticking; clean and lubricate to ensure the latches reset properly.

Why does the outside pole of my Southern States Switch not close?
- M
  Michael FischerAug 10, 2025
  If an outside pole does not close, it could be due to insufficient shunt trip gap in the open position. Adjust the gap using the shunt trip charging bolt.

What to do if Southern States Circuit Switcher Opens 1 Second After Trip Initiation?
- K
  Kyle GarrettAug 15, 2025
  If the circuit switcher opens 1 second after trip initiation, it could be due to a trip circuit electrical problem. Check the continuity of the circuit.
