Depends on what you are going to do with it. 300' of 16awg drawing 4a will
drop about 9.5v. Most things won't care about that low of a voltage drop.
But consider that you are loosing about 8% over that distance. Also
consider surge loads like motors starting and such. Powering a few lights,
no problem. Starting a motor (like a drill or fridge compressor), might be
an issue. If the motor start current is double the running current, you
now have a drop of over 19v this is a big hit. By contrast, moving up to
14 gauge will get you down to about 6v drop or only 5% loss steady state
and 12v drop surge. Might be worth it if you have larger surge loads and
equipment that cares.
