Depending on the equipment configuration, the circuit breaker can be
mounted using different styles of hardware . The following steps describe
how to mount the circuit breaker using standard hardware . When special
hardware is needed (for example, with the motor operator), the Instruction
Leaflet describing the accessory also describes the special mounting arrange-
ments .
2-6 . To mount the circuit breaker, perform the following steps:
a .
For individual surface mounting, drill the mounting panel using
the drilling plan shown in Figure 7 . For panelboard mount-
ing, only load end support mounting holes are required . For
Deadfront cover applications, cut out cover to correct escutch-
eon dimensions, see Figure 8 .
b .
If the circuit breaker includes factory or field installed internal
accessories, make sure accessory wire is accessible when
the circuit breaker is mounted .
N
otee:
Labels with accessory connection schematic diagrams are provided on
the side of the circuit breaker .
c .
Position the circuit breaker on the mounting surface .
d .
Install circuit breaker mounting screws and washers . Tighten
screws firmly, but do not exceed 28 lb .-in . (3 N .m) .

Install both the line and load terminal covers on the circuit
breaker cover with mounting screws provided . Torque to
20-22 lb . in . (2 .26-2 .49 N .m) .
2-10 . When step-type terminals (Cat . No . TA603LD) are used, ter-
