Restrictions
Can be installed in any bus position A-D (row 1-4) of a 1-, 2-, 3-, or 4-bus row cabinet.
Unless otherwise specified fuses and/or circuit breakers are mounted from left to right, starting with the
highest capacity and working to the lowest capacity.
125A, 150A, and 200A circuit breakers occupy two mounting positions. 250A circuit breakers occupy three
mounting positions.
Caution: A circuit breaker or fuse with a rating greater than 150 amperes SHALL HAVE an empty
mounting position between it and any other overcurrent protective device.
Maximum size of wire to be connected to a single fuseholder or circuit breaker position is 2 AWG.
