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.
