The sub-fed (linked) panel is shown indented in the tree view in the left pane.
NOTE A warning symbol appears if you try to create a circular reference by linking a panel back to
the panel that feeds it.
NOTE You cannot link a panel to more than one panel at a time.
NOTE Anytime you add or delete circuits, you will need to update any existing panel schedules. See
Updating Panel Schedules on page 459
To remove a link between panels:
➤
Select the panel and click Panel tab
➤
Connections panel
➤
Remove Connection To .
NOTE You can connect to a panel only once using either the feed-thru lugs, subfeed lugs, or subfeed
breaker option. You can use the circuit breaker option only when there are available circuits.
Managing Circuits in a Project
As you create and refine your electrical system designs, you can manage your circuits using the following
tips:
■
Use an electrical project database file to manage circuits across all drawings in a project.
■ Create circuits when you add a panel , or add circuits to panels later using the Circuit Manager .
■ Configure circuit settings only in the drawing that contains the circuits. After you assign at least one
device to a circuit, many of the circuit settings are no longer editable.
■
Configure loads for device styles so that the load is automatically configured when you add the device
to a drawing.
■ Assign devices to circuits as you add the devices, or add the devices first and then assign them to circuits
later .
■
Keep circuit data current in multiple electrical drawings by reloading the electrical project database .
■ Configure electrical preferences so that you are automatically notified of circuit overloads for power and
lighting circuits.
■ Use circuit-checking features to see circuit information for a selected device. You can also verify circuit
connectivity to display the devices that are assigned to the same circuit.
