Do these numbers apply to stranded too? (I believe the power cord is stranded)

My concern was just that at startup (or when bogging down) it will
draw more than the rated 13A/1.5HP so that maybe moving to 12 gauge
would help me out given that the total cord length is about 15 feet.

I would like to do that but the manual says "It is wired for
operation on 120 volts, 60 Hz alternating curent. IT MUST NOT BE
CONVERTED TO OPERATE ON 230 VOLTS". Now someone mentioned in another
thread that this may just be due to the fact that the switch only
switches one leg and that everything would be ok if I swapped in a
DPDT switch to switch both phases.
But I don't have any manual for the motor itself and don't know what
needs to be rewired.
