Terminal Diagrams for Switches

This diagram illustrates the terminal configuration for a non-bank three-phase or one-phase switchable device. For this type of device, the descriptive attributes are found directly on the feature in the device feature class.

Terminal Diagram for Switch Bank with connected units (Unbalanced)

This diagram illustrates the terminal configuration for a bank of phase-dedicated switchable devices. The bank is represented by a two terminal feature in the device feature class. For this type of device the descriptive attributes are per phase, and so are found on the rows of the JunctionObject table that are contained by the bank feature. Switch types that use this terminal configuration should belong to the E:Has Connected Units network category.
