Distribution Devices
Bullet Nose Type Circuit Breakers
Features
♦
Circuit breakers with ratings of 1A through 100A each plug into a single mounting position. Circuit breakers with ratings
of 125A, 150A and 200A each plug into two (2) mounting positions, and those with ratings of 250A each plug into three
(3) mounting positions.
Restrictions
Load should not exceed 80% of device rating.
Single Row Distribution Assembly: In a +40 °C ambient, 100 A circuit breakers can be used without a space provided the
continuous current in each device does not exceed 64 A. Overcurrent protective devices greater than 100 A shall have an
empty mounting position between it and any other overcurrent protective device.
At or above +65 °C, the maximum size overcurrent device used shall be 70 A. Devices rated at 70 A or less shall have an
empty mounting position between it and any other overcurrent protective device.
Two Row Distribution Assembly: In a +40 °C ambient, 100 A circuit breakers can be used without a space provided the
continuous current in each device does not exceed 64 A. 100 A fuses, 150 A and 250 A circuit breakers do not require a space
adjacent to it.
At or above +65°C, the maximum size circuit breaker used shall be 125 A. The maximum size fuse used shall be 70 A. Devices
rated at 50 A or greater shall have an empty mounting position between it and any other overcurrent protective device.
