Bullet Nose-Type Circuit Breakers 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 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.
