Wire size focuses on VD, Fill, Ease, etc, But now, for VT sparky's it also focuses on AFCI's in their requirement of ALL bed & living area circuits. So this in itself forces us to rethink methods, or pitch for a lot of the little boogers

Once the above is considered, all we really need meet is T220-3(a)'s 3VA per square, that's all.

VD..
a #12 @16A (80%) has approx 4.8v or 4% loss @ 75'
a #14 @ 12A (80%) has approx 4.8V or 4% loss @ 65'
not a world of difference eh?
