After you create circuits, configure circuit properties, such as voltage, rating, load category, and system.
- Open the drawing that contains the circuits and select a device.
- Click
.
- In the left pane of the Circuit Manager, expand the panel, expand the branch (for example, Power and Lighting), and select the circuit to be configured.
To edit properties for multiple circuits, select the branch in the left pane that contains the circuits. On the right pane, use Shift or Ctrl to select multiple rows in the circuit list view.
- Double-click the circuit property field in the right pane.
- Enter the new information, or select a new property from the list.
Depending on the system type, you can modify the following properties:
- Name: Specify a name, using naming conventions for new circuits using electrical preferences.
- Description: Typically a brief description of the type of devices and the area of the building this circuit will service.
- System: The electrical system definition for the circuit.
- Rating (Power and Lighting only)
- Voltage (Power and Lighting only)
The number of devices and circuit length are calculated for you as you assign devices to circuits. For power and lighting circuits, the total load is also calculated for you.
Circuit length is calculated only if the devices and circuits are contained in the same drawing. Typically, you assign devices in one drawing to circuits in the electrical project database file. In that case, the circuit length always displays as <Used in multiple drawings>.
After you assign one or more devices to a circuit, not all properties are editable. To reconfigure a property for a circuit with devices assigned to it, you can modify the devices, set their circuit assignments to <Unassigned>, and then modify the circuit property in the Circuit Manager. You can also create a new circuit, configure it as desired, and modify the devices to assign them to the new circuit. Then, delete or reuse the old circuit.
If you are using an electrical project database file, and you configure a circuit that is being used by devices in other drawings, you are prompted to open and save the affected drawings to ensure that the circuit information is current. For more information, see Electrical Project Database.
