Think about that when you use 5% Volts Dropped. That is basically 5% tacked onto their electricity bill.
That is a not really the case, a 5% VD will not directly mean a 5% increase in the electrical usage. It will not even be close, the wasted power due to VD will be an very small percentage of the total bill.
That aside I do agree the customer ends up paying for electricity not directly use by them and if they are willing to pay up front for larger conductors it is a better job overall.
