    I have a 400 foot run to light up 12 100 watt light bulbs 120v, I am wondering if there was rule of thumb to figure out the voltage drop?
    I know that no.10 awg should be good enough but is there a easyer method than all the calculations to get a 3%drop or less?

    Table D3 in the CE Code will do it.
