I'm wiring in a new PSX-AR on a reverse loop of about 12 lineral feet. MY question is do i need to run all my feeder wires from my bus through the PSX-AR, or just one set and connect the rest directly from the bus to the track. or am I not understanding the directions I have?
Your PSX-AR should get its power from the power bus (or from the command station directly). The track in your reverse loop should then get power only from the PSX-AR.
Good luck!

So I should run the three feeders to the loop threw the PSX - AR module right?
or should I say, From the power bus to the PSX-AR and from the PSX-AR split off three feeders to the loop. OR do I only need one feeder?
Ideally you should run a fairly heavy gauge wire from the PSX-AR under the loop track and then two or three feeders from that sub-bus to the track. Conventional wisdom says feeders should be, within reason, as short as possible. Again, conventional wisdom says to have feeders about every six feet. So for twelve lineal feet a couple of feeders should be fine so long as they are no longer than about 12"-15" in length.

If the reverser is located more or less centrally along the gapped reversing section of track, then run two pairs of thin feeders wires off of each terminal to the appropriate rails, one pair going left (one wire from each post going one direction) and the other pair (one wire from each post) going in the other. However, it would be perfectly fine if your reversing section stretches out in one direction away from the reverser to wire a slightly heavier gauge pair somewhere close along the gapped section, and then tap into that pair with lighter feeders that will be soldered to the rails another 4-6' along, closer to the far end. Or, use the same slightly heavier gauge as the first. I have 22 gauge feeders nearly 4' long that feed lots of substantial lengths of track with no noticeable deterioration in signal and short-detection. I am sure there is a reduction, but not such that my trains refuse to play when I do.

Thanks guys thats just the answers I was looking for
