Distribution Panels
Each 28-position distribution panel accepts bullet-style circuit breakers and fuseholders.
Single-pole breakers through 100A, two-pole breakers through 150A, three-pole
breakers through 250A and fuses to 125A may be installed in any position with no
spacing restrictions. Panels come with hinged front doors equipped with plastic slot
fillers. As circuit breakers or fuseholders are installed, un-snap the plastic slot filler and
replace with a circuit breaker or fuseholder. Store the excess plastic slot fillers in the
hardware bin in the back of the cabinet. Note: breakers/fuseholders can only be
installed one way or the front hinged door will not close properly. Each distribution
position has three alarm pin openings. The outer alarm opening is the alarm output.
Alarm pin of protector should insert into this opening. The inner two openings are
provided because some breaker styles have additional pins that require alarm power to
generate the output alarm.
