There was a good youtube clip (?v=xjSV447EVtQ by nwteacher) that helped me learn more about soldering the 18 gauge wire to the rail， This is all normalized at about a 3 amp draw， though I will not connect it underneath the rail as he did)。

The 18 AWG has almost one-fourth the voltage loss of of 22 AWG. You can likely handle 6 to 8 feet of 18 AWG run (compared to 4 - 6 of 22 AWG) from your 12 AWG buss with only negligible loss of voltage (less than one quarter volt). -ed- _________________ -ed mccamey- COSLAR RR - NMRA Standards and Conformance Department PROTO FINE Scale Coordinator I estimate I have about 5 pounds of coupler springs somewhere in the vicinity of my workbench. sambear Post subject: Posted: Tue Feb 23， clean - clean - clean. The wire connections must be soldered with non-acid (rosin fluxed) solder. The rail base and side must be cleaned thoroughly， and tin'd iron. I use the HN solder flux Super Safe and it makes a difference. I also recommend you pre-tin the lead wire - when you hit the joint with the iron - things just melt together and bond well almost instantly. Soldering is just a technique that some modest practice makes for good skill. Its not an 'art' or in any way really difficult. Take the time to practice some and become focused on all the technique (clean，。
and breaking is not an unusual occurence. I have used #18THNN stranded wire for my buss to rail (soldered) connections， which I have ran as @12THNN stranded throughout the network. The previous post was on the mark about 22 or 24 not being adequate for this type of wiring. All wire has resistance and it varies by several aspects. Your best bet is to hit your local electrical supply house and buy your rolls in commercial (500' rolls) and not monkey around with lesser grade material. Also。
and use suitcase connectors at the buss。
and presumes solid good copper connections. (Caution not all wire is actually supplied as pure copper)! #18 wire is ~ 0.034 volt loss per foot。
2010 11:09 am Posts: 1 Sambear; An improperly soldered connection of this type will not perform well， 2005 10:48 am Posts: 365 Location: East Texas - USA sambear， not sure to use my solder resistance station or just the Weller iron. Just hope suitcase connectors (once I find them) work well keep the 18 gauge leads tied to the 12 gauge bus. _________________ Life is about learning Page 1 of 1 [ 7 posts ] ， 2010 11:34 pm， 2010 10:38 pm Joined: Sat Aug 13， Page 1 of 1 [ 7 posts ] Print view | AuthorMessage sambear Post subject: Posted: Sat Feb 06， 2007 1:18 pm Posts: 84 I went through a lot of places but only found 18 AWG wire for the attachments to the rail from the 12 AWG bus rail.

I probably made a big mistake by connecting the wires to the rail before placing the rails down. I did it three times and each time the wires broke off the rail. It also was very hard to move the rail while trying to connect to the next rail and even dropping the wire through the holes was very tough. _________________ Life is about learning Richard Cormier Post subject: Posted: Sun Aug 15， a 20 or 22 gauge is only to be length of 10 cms (4 inches)。
