Reply to "Circuit breaker in Lionel kw transformer(10 amp)"

Based on that graph ,I would say my 10 amp breaker is fine and all those breakers really protect against is a dead direct short. I could never get it trip at 14 amps but I only did it for a couple of minutes as I did not want to damage my transformer. Nothing got real hot on the transformer at that amperage. In realty a 7 or 7.5 amp would likely run indefinitely at 10 amps or one **** of a long time thus really being closer to a 10 amp rating( if you want something to trip a little above 10 amps as a rated10 amp breaker will not.)
