WARNING
The voltages in energized equipment can cause death or severe personal
injury before mounting the circuit breaker in an electrical system, make sure
there is no voltage present where work is to be performed. Special attention
should be paid to reverse feed applications to ensure no voltage is present.
Note: 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 arrangements.
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 4. For panelboard mounting, only load end support
mounting holes are required. For Deadfront cover applications, cut out
cover to correct escutcheon dimensions, see Figure 5.
