That is all and well great, but not everyone is in strictly command la-la land with empires needing 40A of track power. This thread documents a different solution for different needs.
@gunrunnerjohn posted:First off, I personally wouldn't be configuring my power so that I had one transformer that maybe delivers 12-13 amps powering four power districts that had 10 amp breakers.
Absolutely no general argument from me on that!
@gunrunnerjohn posted:In the scenario of the ZW, I'd probably consider a common breaker of maybe 15 amps for all the circuits replacing the lousy ZW circuit breaker.
I have rarely found a internal breaker that is outside of Lionel's spec - I find more often people are surprised at Lionel's spec. However, it serves it purpose as intended - to protect the upstream transformer. So instead of modifying a perfectly serviced and usable ZW, just supplement it externally with the Instant AirPax units as discussed in this thread with sub circuits strategically sized for the expected load and keep the total load below a constant 12A and under extended 15A peaks. This can also add cross throttle/circuit/terminal fault protections, something lacking in many classic transformers.
