Referring to the following post:

From the chart and doing the calculation for a 20 foot run 16 guage would be quite adequate. If you have to go a bit further 14 would handle it fine.
Oddly enough, I agree.
While #16AWG may be electrically adequate (ampacity & voltage drop) when new; I'd also prefer #14 for mechanical (strength) reasons, and allowing for more leeway for inevitable electrical degradation.
