(See Fig. 1) To mount the circuit breaker perform the following steps:
1. For individual surface mounting, drill and tap mounting bolts holes according to the drilling plan shown in Fig. 2.
For dead- front cover applications, cut out cover to correct escutcheon dimensions refer to Fig. 3 .
2. If circuit breaker includes factory-or field-installed internal accessories, make sure that accessory wiring can be reached when the
circuit breaker is mounted.
3. Position circuit breaker on mounting surface.
4. Install circuit breaker mounting screws and washers. Tighten hardware securely, but do not exceed 13.3 pound-inches (1.5N.m.)
