@CelloMomOnCars Yes, AWG is weird, but I don’t mind it too much, even as a European. It’s easy to remember whole numbers, and with a few of them in mind I know that 18 is for power, 24/26 is normal, and 30/32 is near invisible (depending on your application, of course.) I might even remember that the cross section doubles every three gauges. And for the rest, there are tables. @tilton
