screws used to attach the access cover to the side of the
transition box on the insulating support column. See
Figure 10. Remove the cover and place it and the
hardware on a clean surface. They will be re-used in
Step 31.

Step 21

Prepare the interrupter for removal as follows. See
Figure 10.

(a) Attach the spare stop bracket (marked with a

black/yellow striped label) and spacer (marked with a

(b) Remove the pin retaining clip and connecting pin

which attach the coupling to the operating rod link.
Discard the connecting pin and pin retaining clip.
