22 guage wire ok for feeders

Discussion in 'DCC & Electronics' started by basementdweller, Aug 30, 2004.

  1. I am using HO scale, DCC. I was using 20 guage for my track feeders and now I need more wire. I have plenty of 22 guage solid wire, will this be heavy enough? I have been running a feeder to each piece of flex track.

    I use 22 gauge to some of my spurs and it works ok.

    The guy in my electronic shop told me that I could run two wires parallel to get the effect of using a thicker wire.

    I used #22 for feeders on my layout - about 200+ ft - every other section of track and it seems to work fine.

    #22 is fine for feeders, assuming you are only using it from the rail down to a bus wire below the roadbed, say no longer than 6". Particularly if you have feeders frequently, I like to feed every rail tho that may be overkill. Voltage drop over short lengths will be insignificant. Your bus wire should be heavy, I use 14 gauge.

    Actually it isn't overkill. You don't have to have a voltage drop to need frequent drops. If you don't have a feeder soldered to every section of rail, you are asking a rail joiner to carry the power from one rail section to another. Rail joiners make mechanical connections, but are lousy electrical connectors. If you use a feeder drop for every rail, you'll have good reliable power for the entire layout.

    All too true Russ, and the reason I feed each rail. But sometimes I'll solder a feed to a joiner which is in turn soldered to both rails it joins. In that case you can have feeders every other joint, leaving the other joints unsoldered.
