I was wondering about whether it is wirth the effort to test circuit breakers on Lionel transformers. I just had an inquiry about that from a buyer to whom I sold a KW. So I did query on this forum and found this long discussion from several years ago.
I have a few follow-up questions.
It seems like a spectacular short is needed to test the breaker on a ZW. I don't want to play with making a 10 amp short.
My conclusion is that testing isn't worth the trouble. When I sell a transformer on Ebay, I note that I have no way of testing the breaker.
I don't use circuit breakers at all on my layout, which si a 7x11 teswt loop and a few sidings. IF I do have a short, not unusual, I can hear, see or smell it and occasionally my RW breaker trips.
I'd be interested in any comments that those with more experience than me may have about my observations
