Suitcase Connectors For Layout

Howard asks for advice from others in the hobby:

“On the new HO layout I will probably solder feeder wires to the flex track at the workbench. I don’t want to solder under the layout this time. What color suitcase connectors should I use and what size wires will they use? I’d prefer to use solid copper #12 for the bus wires and 22 solid for the feeders. Who has done this and can tell me about it? Thanks.”

Add your suggestions.

    Howard,
    I just started using suitcase connectors, and I think they are great. Go to MicroMark.com to get the exact specifications on wire size. As I remember, if you want to use #12 bus wire, you will need the brown connectors, but you will have to move up to #18 feeder wires because of the way the suitcase pairings are sized. If you want to use #22 feeders, you should use the red suitcases but you would have to reduce the bus to #14.

    I also believe suitcase connectors are great and have a lot of advantages. Suggest using the same color for bus wiring, another for feeder wires, and a third for accessories. Keeps the confusion to a minimum.

    I use common wire nuts quite frequently. It facilitates adding connections, temporary disconnects and rearranging the wiring.

    Unless you have a very large layout, I would recommend #14 for the bus wire. #14 is OK for a run of up to 50ft and 5 amps. If you have a greater run or will use more than 5 amps then go for #12. If you go for the #12 then you will need the brown connector, but will need to increase the size of the feeder wire to #18. As Grand Pere said, the red connector is the one to use – from Micro Mark (#14 bus and #22). No need to buy the special crimper tool ($USD80) – a wide jawed pair of pliers does the trickI reckon they are the greatest invention since sliced bread! Just a word of warning, be methodical when you install them i.e. the correct colour feeder on the correct colour bus wire – I have had to redo the connection more than once after being in a hurry to get a section done!

    Thanks guys for all of your comments. I will have some runs that are over 50 ft., so it looks like
    using 12 for the bus wires was the right decision.
    Appreciate it.

    I am running #16 guage trailer wire for my bus feeds under the rails and you can get the wires in various colors in 100 foot rolls. So far so good with DCC and I am feeding all the way around the garage with no drop in power so far through 200 feet of track. I am using short house phone wire (solid) for my drops every 4 to 8 feet apart and soldiered them to the connectors (basically the same as feeding to each modular ensuring I have drops installed both sides of switches and in between switches to prevent power loss. I do not soldier direct to the rails unless I just have too.

    I just started using Red and Blue suitcase connectors. They are the greatest thing since the electric toaster. Red works well . Bus wire in top channel and 22 gauge feeder in bottom hole. I also use the blue ones, again Bus wire in top channel, and if you drill through bottom hole, you can run two ,22 gauge feeder wires, one from each direction and save some money. Both have yet to fail me.
