One sure fire way is to use standard US terminal strips with strip connectors (often included with the terminal). Generally they’ll take 12 and higher # gauges.

You can continue the buss directly across from the incoming buss wires and use the connectors to feed the buss wire(s) to a number of small feeder wires.

Terminal strips up to 24+ screws, 8 (16 screws) being typical. They don’t cut into the wires like suitcase terminals and are much easier to rewire & reuse.

I moved away from suitcase connectors a few years ago. Instead I use Wago Lever Nuts. They can handle anything from 12-28 AWG wire. They are a terminal connector that comes in various sizes. They are rated for house wiring so are a bit of overkill for model railroads but the ease of use and convenience certainly is a big plus.

Don’t be afraid of 12 gauge if that’s what you’ve got. Personally I’d solder the droppers to the bus rather than rely on proprietary fixtures.

I got the NCE wiring kit and that has 22 AWG for the droppers and 14 AWG for the bus. Their instructions talk about the “blue (or yellow) bus tap connector providing a female socket for the red connector of the power drop. Blue taps are provided for 14-16 AWG bus wires to
used with up to 5 Amp DCC systems, Yellow taps are for use high powered DCC
systems of 8-10 Amps with 10-12AWG main bus wiring.” So I think the answer to your question is yes.

I’m not an expert, but 12 AWG is awfully large. 14 should be enough. Now, as to connectors. I have used WAGO and the ones I bought accepted 28 through 12. So, check out there web site on Amazon.
