Circuits connect similar electrical components to form an electrical system. Once created, you can edit circuits to add or remove components, connect a circuit to a panel, add wiring runs, and view circuit and panel properties. Wiring is not necessary, but can be used to show wiring that is exposed or concealed within walls, ceilings, and floors.
A component can be connected in a circuit if it is compatible with the other components in the circuit and if it has an available connector. Using Revit, you can create circuits for two system types:
You can add a device to an existing circuit when its distribution system matches that of the existing circuit. When adding a device with the distribution system specified as instance parameters, the distribution system for the device will assume the values of the circuit where it is being added.
