a CLOSED breaker. Do not reach your hands into
the mechanism while adjusting the flux shifter.

Place a #10 flat washer over the supplied #10-32
bolt. Insert the bolt through the hole in the breaker
reset link [7]. Place a flat washer over the bolt, then
slide the bolt through the slot in the flux shifter
reset arm [1]. Place a flat washer and the self-
locking nut on the bolt. Tighten the nut so that the
bolt is still free to rotate.
Flux Shifter Test
The operation of the flux shifter may be tested by
closing the breaker, then applying 9 Vdc to the flux
shifter leads (red is positive). The breaker should
trip and reset. If necessary, repeat the adjustments
