16 strands of 23ga is 4.01 mm^2
one strand of 11 AWG is 4.17 mm^2
two strands of 13 AWG is 5.26 mm^2 :D (probably wont fit :( )
two strands of 14 AWG is 4.16 mm^2 :)
three strands of 16 AWG is 3.93 mm^2 :(

im thinking two strands of 14 gauge for being the easiest to pull, and still get a good copper fill, but ill order dome 13guage first, and see if i can get it to fit :D



what's the objective on deciding what gauge wire to use ?
the more copper fill, ok, so you got here 14g and 11g giving same copper fill and i am sure smaller gauges at some points will give also same copper fill, but what gauge should we aim for, lets say not 11g because the insulation might crack, 14g wont crack, 18-28g wont crack either, and assuming some wires between 18-28g will give same copper fill, then how do we choose what to use :?

you would've ordered more than 3 sensors LOL
it's a pitty i wont stay to see the world crumble, u jedi Scum
