INSTRUCTIONS
NOTE: The circuit breakers are not supplied with these
kits and are shown only for convenience.
1. Select the table which applies to your enclosure.
2. Determine the enclosure flange width “B” and the
mounting depth “H” to ensure the cabinet is at least as
large as these minimum values.
3. Refer to N.E.C. for required wire bending space, Di-
mension “C”. The minimum value given for “C” is the
minimum wire bending space for the maximum wire
size that can be connected to each circuit breaker for
its current rating.

INSTALLATION INSTRUCTIONS
Operating Mechanism
NOTE: For ease of assembly it might be advisable to
install the circuit breaker operator and then the circuit
breaker.
1. Remove nuts and washers from flange plate.
2. Place the operating mechanism into the enclosure with
the operating handle in the ‘Off’ position. Tilt the
assembly under the flange and at the same time bring
the handle through the slot provided.
3. Place flange plate studs through the holes in the flange
and mechanism frame while holding the assembly
against the under side of flange. Secure assembly to
flange.
4. Attach operating mechanism mounting bracket firmly
to the enclosure mounting plate surface. See line
drawing Page 1 (Bolts and spacers are furnished by
user).
NOTE: It is recognized that holes in the enclosure
mounting plate surface used to secure the circuit breaker
operating mechanism can be located previous to installation. Refer to line drawings on Page 2.
Circuit Breaker Operator Mechanism
1. Place the circuit breaker Operating Mechanism handle
in the “ON” position by first pushing the defeater
by-pass lever upward and then moving the operator
handle from “OFF” to “ON”.
2. Place circuit breaker toggle lever in the “ON”
position.
3. Place circuit breaker Slide Mechanism on top of
breaker so that the slide bushings seat in the breaker
mounting holes, the toggle lever is through the slide
slot and the slot for receiving the bellcrank roller is
oriented

6.
Position circuit breaker assembly obtained in steps 3
and 4 so that the breaker line terminals are toward
the “ON” direction of the Operating Mechanism
handle and the bellcrank roller (operating mechanism) is in the bellcrank slot (slide mechanism).
Align the four circuit breaker mounting screws with
7.
the proper tapped holes in the Operating Mechanism
frame mounting surface. See illustrations on Page 2
for ITE and Westinghouse mounting.
8.
CAUTION: Position circuit breaker so that mounting
screws are perpendicular to mounting surface and
secure the breaker to Operating Mechanism frame by
tightening the mounting screws.
NOTE: The circuit breaker can be secured onto the
Operator Mechanism mounting frame either before or
after the Operator Mechanism has been secured to the
enclosure flange.

Move Operator Mechanism handle from “ON” to
“OFF” and then from “OFF” to “ON” to ensure
proper mechanical and electrical operation.
CAUTION: Place Operator Mechanism handle in

GUIDELINES
Small Enclosures: 30” high or less with 2 or 3 point latch-
ing. Intermediate Enclosures: 30” thru 48” high with 3
point latching. Large Enclosures: Above 48” high with 3
point latching.
INSTRUCTIONS
1.
Check all minimum enclosure and door dimensions
required for installation. Refer to Page 1 and above.
2. Select the dimensions from above which apply to the
roller latching arrangement to be installed.
NOTE: Door catch supplied with operating mechanism
is not to be used with these door hardware kits.
3. Locate holes in door to secure handle assembly.
4. Determine Dimensions “B” and “C” to locate locking
bar guide bracket(s).
5. Locate door catch using “P” and “T” dimensions. Location varies with each hardware kit. On 1494F-L4
hardware kits, attach the adjustable catch after the
support bracket is located. NOTE: Door catch and
guide bracket(s) are made with projections for welding
to the enclosure door. However, if a specific installation permits, holes can be drilled in the door catch and
guide bracket(s) using the projections as centers. Then,
after proper location and using them as templates,
corresponding holes can be drilled in the enclosure
door. Door catch and guide bracket(s) are then fastened to the enclosure door with hardware furnished
by user.
6. Establish the length of the top locking bar by meas-
uring Dimensions “E” and subtracting 3/4" for Kits L1
and L2; subtract 1-1/8" for Kit L4. Determine the
l
ength of the bottom locking bar by measuring Dimen-
sion “K” and subtracting 3/4" for Kit L2; subtract
l-l/8" for Kit L4. Dimension “H” is determined by
measuring Dimension “D” and adding 3-3/4" for Kits
L1 and L2; add 3-5/8" for Kit L4. Locate, drill, and
tap holes where necessary. NOTE: These standard mill
rectangular locking bars are not supplied with these
kits.
7. The door locking hardware assembly can now be attached to the door.

Locking Bar(s) and Handle Assembly
Using the roller latching arrangement to be installed and
the locking bar(s) prepared as specified on Page 4 proceed
as follows:
1.
Insert cam bearing(s) into the cam plate hole(s), insert
locking bar(s) in the cam bearing slot(s) and secure b
using the pin(s) provided. See above. NOTE: An alternate method requires using the screw(s) and nut(s) also
provided.
2. Remove door handle and cover plate from the handle
assembly.

5. Replace handle.
NOTE: An alternate method of assembly requires that the

handle assembly beinstalled first and then attach locking
bar(s) to the cam plate.
Roller Assembly and Defeater Actuator Lever
Attach top roller assembly and bottom roller assembly
(when used) to the locking bar(s). A slotted hole on
roller assembly provides adjustment to insure proper
gasket sealing when enclosure dimensional variation
are encountered.
Fasten side roller assembly (when used) to the cam
plate using various shims supplied. Nominal enclosure
dimensions will require one (1) 1/8" shim
Attach the defeater actuator lever to the upper locking
bar. Refer to inset for assembled view as seen from
inside of enclosure. The two screws should be located
near the center of the adjustment slot. Refer to Dimension “A”. Further adjustment may be required after
disconnect switch is installed
.
.
Door Hardware Adjustments
With the operating handle mechanism secured to the
flange in the “Off” position and the door hardware attached to the door proceed as follows:
1.
Close enclosure door and slowly turn the handle to the
right (counterclockwise) until the first notch on the
cam plate is engaged. At this point positive gasket seal
should be obtained with proper roller adjustment.
When seal is obtained further adjustment to the defeater actuator lever may be required if the operator
mechanism handle can be moved to the “On” position.
Rotate door handle further to the right. Relocate
2.
defeater actuator lever if necessary, so that the operating handle mechanism “On” position occurs well
before the fully latched (vertical) door handle position.
3.
With the operating handle in the “Off” position, turn

turn handle to the left and pull. Door should open.
Close door, turn door handle to fully latched position
