We have an old Challenger 1200 amp frame ground fault breaker that has tripped multiple times. The breaker has a 1000 amp rating plug installed. We are unable to find any documentation on this breaker to be able to properly set it. We think the pickup frame rating should be set at 960 not 120. Any comments or information on this breaker or the settings would be much appreciated.
