The primary disconnect assembly is factory-adjusted to apply a 95 + 10 Ib. force to a1/2-inch
thick copper bar, inserted between the upper and lower fingers. Set this force range, in the
field, by tightening the nuts to set the spring dimension shown in Figure 59/60. Note that
this dimension is measured between the top of the retainer and the underside of the washer.
Also note that no bar is inserted between the fingers when setting this dimension.
Figure 61/62 shows the cluster components.
