Net node is an item related to networks. Net nodes define end points for Net Lines. Each Net Node can be connected to one or more Net Lines.
Net loads can also be attached to a Net Node, but a Net Node can currently only be connected to one load per Net Type.
A Net Node does not belong to a particular Net Type. Instead, it is part of a Network of a particular Net Type when it is related to a Net Line or referenced by a Net Load of a particular Net Type.
