Your common available sizes for bus are probably 2.5mm ^2 and 4.0 mm^2.
2.5 is between 14 & 12 awg and 4.0 is between 10 and 12 awg.
2.5mm will be fine for most layouts.
You could also look at auto cable from Supercheap. 5mm 25 amp is 2.90 mm^2 so more than adequate for bus. I prefer house wire though as it is more rigid.

If I am not mistaken, wires are defined in millimetres squared for guages. AWG 12 is equivilent to 3.31mm^2 (or something a little heavier if they round off the numbers).
AWG 12 is 4mm^2, 14 is 2.5, 16 = 1.5, 18 = 0.75 and 20 = 0.5 according to a chart I have.
I'll have a look at work for more details on metric wire sizing.
tomcatCan somebody shed some light on what is 12, 14, 16, 18, 20, 22 AWG wire in millimeters.
Thomas:
I took a piece of 14 guage solid wire and measured it a 2 millimeters. Perhaps this will provide a start.

However of this you are wrong. The Earths true orientation can only be viewed from space. You can see Australia is clearly in the upper left hand corner.

There are many calculators on the Internet. I need them. Up here, we use the wrong measuring system.
If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
Regardless of size, if you are in the Southern Hemisphere, do you have to twist the connections clockwise or counterclockwise?

Have been asking a few electronics people here in Australia about AWG wire size and nobody seems to understand what Im talking about.
In the US i understand AWG terms but over here in Oz we work with millimeters in wire size.
Can somebody shed some light on what is 12, 14, 16, 18, 20, 22 AWG wire in millimeters.
I am about to start wiring for my layout and I am seeking a 12 guage bus for track power and wish to have pobably 18 or 22 gauge for feeders. I just dont know what these sizes convert to in millimeters for us strange folks over in OZ!!
Love to all in the best model railroad contry on the planet..
