Reply to "Post war ZW transformer circuit breaker pops after 5 - 10 minutes of running 3 trains simultaneously; what's up?"

For now, I temporarily added an external 10 amp breaker, manual reset. I first tried a 15 amp, but it did not trip fast enough when doing 'shorting' tests. In fact, smoke came from the where the roller rides against the coil before the 15 amp breaker tripped. So for me, the 10 amp was the ticket. Now, I need to find a 10 amp automatic reset breaker to put into the case permanently.

Also, I connected TVS's on the A and D posts, but they kept tripping the breaker as soon as I cracked the throttle. So, not sure if I have the right TVS. Specs are below. Any ideas?
