Any electricians available? Wire size question...
Here is what I got starting with 240 volts and expecting no more than a 5% maximum drop.
Here is the link to the calculator site so you can change whatever variables you want: Online Wire Size Calculators & Tables
Note that when the voltage drops below around 108 (in a 120volt circuit) or 216 (in a 240 volt circuit), things like motors start burning out much faster.
