bmoran4 posted:@O Gauge Jim, Thanks for your response - it explains your high failure rate. I test my classic transformer breakers to Lionel's published specifications and do restorations for the purist, but will deviate with newer internal breakers, whistle diodes, LEDs and such upon request.
For a test of a stock 1033, a 15 amp draw should trip the internal breaker in 9 to 35 seconds. We both agree, that while this protects the transformer, it is still recommended to have curated external protection on all transformer channels, classic or modern.
BTW, I am in Western NY State.
I found my copy of the Lionel specs for circuit breaker reaction time. Just for the fun of it, I’m gonna take the four units in which the circuit breakers did not meet my specs and retest them to the Lionel specs and I will get back to you with the results. Jim
