Make sure that the lifting bar "J" hooks or generic chain-hooks are secured and locked in
place.
Dropping a breaker can result in injury or death.
Line up the breaker in front of the compartment where it will be installed; then raise it
slightly above the height of the drawout tray assembly and do not move the hoist left to
right with the breaker suspended.
Pull out the two rails being cautious not to position anyone underneath the suspended
load. Pulling from the middle of the tie bar connecting the two rails and lifting up slightly
will help the rails to slide out more easily.
Align the breaker in front of the 5/8" diameter conical topped pins at the rear of the tray
and align the smaller 3/8" diameter pins to locate thru the holes in the breaker frame.
Lower the breaker down on the tray. It should sit flat if the rejection pins pass thru the
rejection plates properly and the breaker was located as in step 6.
Install two 3/8-16
bolts thru the lower breaker frame at the front corners and into the
drawout tray assembly. Torque both to 25 lb-ft.
Remove the lifting bar and or chains.
Check for alignment of the optional Programmer disconnect on the left side in the
compartment.
(It is fragile and will break if not properly aligned).
Push
the breaker
into the
compartment
slowly while observing
the
programmer
disconnect mating and watching for the alignment of the secondary disconnects and
opening of the optional shutter. A compartment interlock rod in the right front will ride
over a cam and drop into position in the Disconnect position.
When fully installed to the DISCONNECT
position, the racking cams will stop on the
racking pins in the compartment and the breaker will be ready to rack in.
Remove the racking tool. (Figure 40) from the storage location on the breaker front panel
and extend the torque bar from inside the handle.
Use a blade-type screwdriver in the slot or rack-out-lock of the breaker (Figure 41) and
turn it clockwise (to the right) so that the racking handle shutter opens.
While turning screwdriver to the right with shutter open, insert racking tool in handle
insertion
hole so that it engages
with
the
racking
mechanism,
and
remove
the
screwdriver (Figure 41).
Rotating clockwise ~37 turns racks the circuit breaker all the way into the compartment.
As the breaker approaches the TEST position, a spring charging motor or undervoltage
release if installed may operate.
(~ 9 racking turns).
Continue rotating racking handle clockwise until position indicator first shows TEST;
then CONNECTED.
When
approaching
the CONNECTED
position, more torque for turning the racking
handle is normal as the primary finger clusters engage with the primary bus stabs.
At the end of 37 to 37-1/2 rotations, the breaker is in its maximum travel position. At this
point primary disconnect fingers have completely engaged with the primary bus stabs.
Remove and store the racking handle in its storage location.
