TLS/TPS Fuses, Bullet Nose-Type Fuseholders, and
Bullet Nose-Type Circuit Breaker/Fuseholder Mounting Assembly – Power/Distribution Bays
Features
♦ Each bullet nose-type circuit breaker/fuseholder mounting assembly can mount up to six (6) bullet nose-
type circuit breakers and/or fuseholders.
♦ Each bullet nose-type circuit breaker/fuseholder mounting assembly is equipped with a shunt for MCA
load current measurements (one shunt per six bullet nose-type devices).
♦ Bolts into bay's distribution device mounting positions.
♦ Load lugs are connected to the existing load busbars provided at the top of the Power/Distribution Bay.
These busbars provide 1/4-20 studs on 5/8" centers and hardware for installation of customer provided
two-hole lugs. For load return lug requirements, refer to Power/Distribution and Power Only Bays
External Busbars in this section.
Restrictions
Load should not exceed 80% of device rating.
Each bullet nose-type circuit breaker/fuseholder mounting assembly requires six (6) distribution bus mounting
positions.
Each distribution bus is divided into half. Each half MUST be populated with distribution devices from left-to-
right, without skipping any distribution device mounting positions within each half.
Bullet nose-type circuit breaker/fuseholder mounting assembly rated for 480 amperes, maximum.
Caution: An overcurrent protective device with a rating of 150 amperes or greater SHALL HAVE an
empty mounting position between it and any other overcurrent protective device within the
circuit breaker/fuseholder mounting assembly.
Refer to the illustrations at the beginning of this section for maximum size of wire to be connected to a single
lug position and maximum lug width.
