Great review Gary. I've used these for a number of years with great results. I have a good size layout with both TMCC and DCS.   I power my layout with basically 2 , 12 amp power supplies. I use 3 TIU's. The layout is sort of a walkaround and the 3 TIU's are placed around the layout so basically the outputs of the TIU's which carry the signal  have much shorter runs.  What you can do is run the wires from the power supply to the input of the breaker. I use a strandard 12 gauge. You can then split the wire as it exits the breaker to the inputs of your TIU. One breaker can handle multiple channels on many layouts.
