This is a bit conservative. #14 AWG is rated for 15 Amps; thus
two number 14 will carry 30 Amps, which is the rating of a single
#10 AWG. The rule is: two wires of the same size are equal to
one wire which is two sizes larger.
2 #20 (5 Amps) equals 1 #16 (10 Amps)
2 #18 (7.5 Amps) equals 1 #14 (15 Amps)
and so on.
