It would be nice if Revit could distinguish/support multiple electrical connectors within, say, a mechanical equipment family or an electrical fixture family. A floor box can have power and data within, but if Revit decides the data connector is more important, it will not be able to tag the power circuit when in the project environment. If you do decide to increase functionality in this way, supporting multiple power connectors within a family would be useful too, so that we could connect an emergency connection on a light to an emergency panel and have normal power come from regular branch circuit panelboards.
