While minimum 16 gauge wire is recommended for power and signal in active TIU mode, I don’t find reference to wire gauge for passive mode. If one has fairly long runs to some track blocks, tiu to distribution block and from there to track blocks, is there an optimum wire gauge for carrying only the passive TIU signal?

Whatever size wire to carry the current. Example, distribution- say 14 or maybe even 12.
Carrying a TIU signal only in passive mode- 24 gauge between the TIU and your distro.
Bigger question, where is/are your inductor(s)- per channel?
Classic diagram of why an inductor is used.

example CAT5 cable (24 Gauge twisted pairs) is sufficient for 100 Meters (330 Feet) in the computer world- easily good enough for 50 feet in the train world carrying DCS signal only- no current to speak of.
Thank you much for the clear explanation. I’m using Zachariah’s new version passive TIU board on each channel, which includes a choke.
