(Part of our ongoing series comparing features in Revit MEP and Design Master to make it clear why our software is better.)

Both Design Master Electrical and Revit MEP can calculate voltage drop on feeders and branch circuit conductors. That’s to be expected in a modern electrical BIM program.

However, according to the Revit MEP Help, “For the purposes of Voltage Drop calculations, Revit MEP always assumes Copper conductors.” (Click the “Wire Impedance Factors” link on this page for where this is documented.)

In Design Master Electrical, you are not limited to calculating voltage drop on copper conductors. We can calculate voltage drop on aluminum conductors, too.
