For a single wire, multiply the loss per 1000 feet value, above by the actual wire lengthin thousands.Note: Remember, amperages are additive along a wire where current is demanded by more than one appliance.Note: Voltage losses are calculated from the formula:Where: V = IR I = current in amperesR = resistance in ohms per 1000 feetV = voltage
