pages.
2.
Assemble external handle and pivot assembly to the
enclosure.

8.
Mount interlock blade and interlock lever extension.
Check the position of the interlock blade as shown
in Fig. 1. before closing the cover.
The external handle should remain against the stop, or
nearly against the stop, when the circuit breaker is
ON.
The external handle must move the circuit breaker handle
to the extreme
OFF
(Reset) position before reaching its
stop.
It must be possible to move the external handle to the
extreme
OFF
(open cover) position. In this position the
operating mechanism is being forced beyond the final
breaker handle position and distortion will be evident on
the operating mechanism parts inside the enclosure. This
will be especially evident on the 800 and 1200 Amp cir-
cuit breakers.
