The 12ga wire is really too heavy. You can use something closer
to 18-20 AWG and still be way over the rated current handling
abilites of the wire.
As far as voltage rating is concerned, I use the standard 600
volt rated soft PVC jacketed wire. I generally wrap the core with
about three layers of black plastic friction tape to beef up the
insulation around the core, and wrap away.
