Is AC really better than DC for long distance? See for yourself.
 
TRY IT YOURSELF but REMEMBER TO CHANGE THE WIRE SIZE FOR AC AND DC
 
DC using #6 wire gives LESS LINE LOSS THAN AC SYSTEMS USING
14 or 12 Gauge extension cord so DO NOT BE FOOLED BY CHEAP TALK!
AC is not the best idea for long distance power transmission but HIGHER VOLTAGE IS!
In-fact to get equal line losses to DC # 6G you would need to run ALL 3 wires as #8 gauge and that's way more expensive!
 
SEE FOR YOURSELF USING THE SOFTWARE BELOW.

POWER DROP CALCULATOR

Remember when calculating DC two-wire and AC three-wire THAT YOU most also change the wire size since the three wire AC generally uses smaller wire sizes than two wire single phase DC systems do. If you do not change the wire size it will APPEAR as if AC is better for long distance wire runs. The truth is the HIGH VOLTAGE is the key to running power over LONG distances.
This has nothing to do with AC or DC.

HINT: Input the wire/cable size example of ONE LEG ONLY of the AC or DC wire being used in the actual wire pack.
