The correct name for suitcase connectors is IDC (insulation displacement connectors) because that is how they work. When I went looking for some, even at an electrical component retailer, I found only ones that suited similarly sized wires. What you will need is ones that allow for the main buss wire you are using ( the one closest to the hinge of the "suitcase") and with the secondary position in the IDC, sized to suit your feeder wires.
3M 905s are usually suitable. The "run" connection is for 14-18, the "tap" connection is for 18-22.
Some folks like the 925X where the "run" connection is for 14-18 but instead of a "tap" connection it accepts a male spade connector, which allows disconnecting the "tap" wire as needed.

Yes, but only as a temporary thing while testing the trackage.Anyone do this?
That is what large pieces of cut open cardboard boxes is for.I know if I'm trying to solder the feeders to the bus wire under the table, I'm gonna have burnt spots in the carpet from falling solder,.
