Creating Circuits

Circuits connect similar electrical components to form an electrical system.

Watch this video to learn how to create circuits for an electrical power system in Revit: Electrical Power Systems - Panels and Circuits. Additional videos may be available on YouTube.

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:

• Power systems include lighting and power distribution systems. When circuits are created for a power system, only compatible devices can be connected. All devices in a circuit must specify the same distribution system (voltage and number of poles). The distribution system can be specified by type parameters or instance parameters. When you create a circuit where all the devices have the distribution system specified as instance parameters, Revit displays a Specify Circuit Information dialog where you can specify values for the number of poles and voltage prior to creating the circuit.

  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.

• Other systems include data, telephone, fire alarm, communications, nurse call systems, security, and control systems. While it is still only possible to connect similar components within a particular system, there are no other checks (voltage or number of poles) for compatibility between the components that make up these systems. It is up to the system designer to maintain consistency of the devices connected in these systems.
