In my country for to calculate the voltage-drop needs to considerate demand factor, so How can I change de formula of voltage-drop for to consider the demand factor and with this calculate de correct size of electric wire, because the size that Revit giving isn't correct, for the especifics normative of my country.
Give me a guide to change de formulas please.

Hello,
This is not possible, it is hard-coded.

Unfortunately as stated, you cannot.
And calculations are pretty useless in Europe as well, unless you decide to route every cable by either editing wire path or drawing conduits for every circuit.
The length given by Revit without editing doesn't display the correct values as well as it only subtracts the XYZ coördinates from the panel to the element. It doesn't follow the cable tray.
Is there any solution for this problem? Voltage drop and cable selection should be done after taking demand factor into account.
