Fuse Block Assembly Kit (P/N
Restrictions
Limit one dual voltage bus (List JA, JB, JC, JD, KA, LB, LC) per power system.
Must be installed in Main Bay
Can be installed in any bus position A-D (row 1-4) of a 1-, 2-, 3- or 4-bus row cabinet. If a distribution bus
module is mounted directly beneath, that module must be a List AA, AE, AK, AM, BA, CA, CF, EA, GB, NA,
NB, RA, or RB. If ordering more than one (1)
distribution 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.
Ordering Notes
1) Order circuit breakers as required per
2) Order fuses as required per
Also order one (1) P/N 117201 bullet nose-type fuseholder per fuse ordered.
3) Order load lugs (two hole, 1/4" bolt clearance hole, 5/8" centers) as required for each distribution position
per Table 9 or 11.
4) Order lug hardware kit,
ground lugs for four (4) positions of a bullet nose-type distribution assembly.
