Buss Wiring Sub Districts

[otp777]

I have read from one source that each buss run needs to be at least a foot apart or there can be interference with decoders.  I am planning on running 3 separate busses off of a PM42.  My question is a concern as this is a shelf layout and there is only 12" in width so each of these buss' will be run parallel to each other.  Is this a problem?

I've had buss line pairs run in close proximity to each other and observed no problems with any decoders.

I agree with Jeff, especially if you use plastic insulated wiring like 14 gauge household wire.

If interference were a problem you could just install wood dividers between the bus wires.

Another solution, if indeed interference were a problem, would be to use something like romex cable.

All of my busses, both command and power, run all the way around my two car garage in a single bundle.

I have never had a problem.

If there is a concern about what is called digital echo then one way to alleviate the problem is a twisted buss line. Especially long buss runs would benefit from a twist per foot of run. In the right side red colord link section click on twisted pair.

 From my shelf where the booster and PM42 are up to the layout, I have 4 sets of bus wires wire tied together. Under the layout at that point, 3 of them head off in the same direction and are held in the same hangers until the first one reaches then end of the area it powers, then 2 continue, until one ends, etc. They aren;t twisted, any more than they naturally twist together when I pulled them, and I have zero issues anywhere on the layout.
