Basic DCC Power Buss Wiring Question.........
Posted by mobilman44 on Thursday, October 29, 2009 12:43 PM

Hi!

I'm putting in the main level power buss wiring on my two level DCC HO Layout and have a hopefully "easy" question.......

For much of the layout, I have three tracks running fairly parallel around the layout.  Two are main lines, one a "sub-main" that connects into the terminals, yard, sidings and the like.  Each of these three tracks will hook to a separate circuit.  To keep the buss wires (#14awg) in place, I am using the circular plastic wire holders that screw into the benchwork.

My question is, is there any problem with running the wires from the different power districts through the same wire holder?  I figure it shouldn't make a difference, but sure want the experts opinions as it is a bear wrapping my ol bod in and around the benchwork legs.

 Thank you,

Mobilman44  

ENJOY  !

I have a double main line with sub lines.  I try to keep the wires seperated as much as possible.  There are a few spots where they run together and I've never had an interference issue with them.

Have you thought of braiding them?

No...okay, I would think winding them would be useful for really long runs, but remember that the rails, themselves, are uninsulated and run parallel to each other only 16 mm apart for extended distances.  They, too, carry the signal and host voltage.

It won't be a problem.

The signal is huge, and not high frequency.  And the signals are all in phase, not fighting eacy other.  Lots of reasons why it should not be a problem at all.

And the source impedance is very low, which makes it very difficult to induce a signal of any strength.  And since the signals are in phase etc etc etc....
