im getting ready to run buss wire around my layout and run feeders for power…im running a mrc power pack right now but soon want to convert to DCC…anyone have any good ideas and or tips for running buss wires and feeders now for a better DCC later on??? plus what DCC systems work the best??? thanks brian
The buss wire is going to be the same whether you’re running DC or DCC. The best approach is to use a large conductor wire for the buss so you won’t have to worry about voltage drops around the layout.
I wired a 20 x 40 foot HO scale club layout using stranded speaker wire purchased in bulk from All Electronics or at Wal-mart for the buss wiring. Screw terminal strips were mounted under the layout every 3 feet or so, the the buss wiring was attached to them with crimp terminals so there would be adequate locations for feeder wires to be attached. This involved quite an expense and bit of labor, but has paid off in the long run by making it easier to troubleshoot the wiring or add lights for buildings, etc.
A few details missing here…like…is it a simple loop layout?..or…will you run more than one train at a time?For a simple loop/one train layout,installing bus wires for DC running will do just fine until you switch to DCC,which will only be a matter of replacing the power supplies.
However if you plan to run a more complex layout in the meanwhile,you will need “block control” for satisfying operation,which will require a whole array of switches to control polarities in different blocks to be able to control individual trains independently.On top of the more complicated wiring,you will need a power supply for each train you want to run.
Since you say that DCC is in your future plans,why not go for it right now?You will save yourself the complexity of block control wiring plus the expenses that go with all the hardware needed (which will become useless with DCC).
I’m not saying that DCC is cheaper,as it can be even more expensive depending on which level DCC system you choose,but considering its advantages over DC for operational enjoyment,it’s all worthed it on the long run.
However,like I said before,you can install buss wires (14 GA. should be OK) following your trackwork with feeders (20 GA.) every three feet or so.You can then connect your DC power pack to this and operate one train (with one or more locos) around your layout and enjoy reliable operation.
A caution…if your trackplan features a wye or a loop,you will still need a polarity control
device (DPDT switch or “Snap Relay”) for this segment with DC,which will have to be activated manually (DPDT) or linked to your turnout control (relay).An electronic circuit could then be installed later on when you install your DCC system.
im only running a large u shape layout…with alot of swtiching…aslo a switch off the main line to another section of the layout should this buss wire system work out ok for me??
