ASSEMBLY INSTRUCTIONS
1. Locate mechanism and circuit breaker or disconnect
switch as per outline and drilling plans on following
pages.
2. Assemble external handle and pivot assembly to the
enclosure.
3. Place spring on the long pin with legs facing away
from the pin head. Connect the handle assembly and
pivot assembly with the long pin.
4. With the handle in the extreme OFF (open cover)
position put the spring legs in place as shown in
Fig. 1.
5. Mount the circuit breaker or discon
nect switch with
the backplate and yoke assembly.
6. Determine brace length as shown on page 5 and
mount in place.
7. Connect operating rod as per instructions in Fig. 2.
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 ope
rating mechanism parts inside the enclosure.This
will be especially evident on the 800 and 1200 Amp cir-
cuit breakers.
