Issue:What poles are used to primary inject a 6 or 8 pole Masterpact breaker?
Product Line:
Masterpact NW, NT
Resolution:
8 Pole breaker: Poles 4, 5 and 7 when looking at the front. These poles will power up the Micrologic trip unit.
6 Pole breaker: Poles 2, 3 and 5 when looking at the front. These poles will power up the Micrologic trip unit.
All poles do meter current, so any pole can be tested if you already have the trip unit externally powered up.
