Hmmm 13a x 2 is going to be a 10 guage cord. Why use a 10 guage cord
on a circuit that is most likely going to be 14 guage all the way back
to the panel?


Because current requirements alone do not determine the guage needed,
equally important is the length of the run. Adding another 10ft of 14 guage
to a circuit that should probably be 12 guage, only exacerbates the
problem. If the extension is 10awg, that will be minimized, likely having an
insignificant effect.
