Fuse Replacement
1. Verify that the replacement fuse size is correct for the
transformer kva rating.
2. Remove the metal cover over the actuator from the
replacement fuse (see Figure 7).
3. Place the lower end fitting against the end of the fuse
with the actuator so that the captive screws line up
with the holes on the fuse bottom and the sides of the
fitting line up with the sides of the fuse. Tighten the
screws into the holes (see Figure 8).
4. Place the upper end fitting (with the hotline clamp) over
the top of the fuse and tighten the set screws (see
Figure 9).
