Adjusting the Flux Shifter
With the breaker in the CLOSED position, the gap
between the adjustment screw and the trip paddle should
be
1 / 32 inch, as shown in Figure 9. For safety, OPEN the
breaker before adjusting the screw with a 1 / 4 -inch
wrench. CLOSE the breaker to check the adjustment.
WARNING: Be extremely careful when working on a
CLOSED breaker. Do not reach into the mechanism
while adjusting the flux shifter.
Optional Test – The flux shifter may be tested by closing
the breaker and applying a 9 Vdc power source to the
flux shifter leads (the red wire is positive). The breaker
should trip.
