Questions and answers
trying to remove the breaker using a socket to the all thread counterclockwise and the all thread comes out indicating the jam nuts are absent. is there another way to remove the breaker.
@george A dupre
To remove a GE AKR Series breaker when the all-thread comes out and the jam nuts are absent, follow these steps:
1. Remove the sensor stud if needed to gain working clearance. This can be done by removing its four holding bolts from the rear of the breaker (refer to Fig. 20 in the manual).
2. Disconnect the neutral sensor and verify proper connection and continuity, ensuring it matches the phase sensors in rating and tap setting.
3. Lift out the sensor and its loads.
4. Tap the terminal board to disconnect it.
These steps allow removal of the breaker even without the jam nuts.
