Reply to "how to add circuit breakers to my old KW and ZW transformers (to safely run TMCC power)?"

Upgrade the circuit breakers inside your transformers to new solid state devices. That will protect your transformers properly, but not the trains. Most OEM CBs I've run across in postwar ZWs are way out of calibration and don't protect anything. 

For protection of your engines, I'm with the guys above: Get the PSX-AC. It is considerably faster acting than what is in the transformer and can adequately protect your engine against short circuits.

As Ron and others have recommended, add TVS devices to your transformer outputs. These will protect your delicate electronics from harmful voltage spikes. HIGHLY recommended that you have these installed!!! Do note that if you are running with a DCS TIU, the TIU has internal TVSs on each channel. But multiple TVSs will not hurt. BTW, if your accessories have electronics, be sure to add TVSs to those circuits as well.
