When you connect devices to a circuit, the circuit description is filled in automatically. To change a description on a circuit, you typically need to change the connected devices, and not the circuit itself.
The load description for each device is listed in the circuit. If more than one device have the same description, it is only included once.
Here are the ways you can change the description.
Panel or Other One-Line Device Connection
If the circuit is a connection to another panel or one-line device, you need to make the change in the downstream panel. Use the “DM Electrical->One-Line Devices” commands. On the right-side of the dialog there is a “Feeder Specification” section. At the top of the section there is the “Description in Upstream Device” toggle that you want to check. The description you enter in the box will be used in the circuit.
If light fixtures are connected to the circuit, you need to make the change in the light fixture schedule. Use the “DM Electrical->Light Fixtures->Edit Project Schedule” command. In the top-right of the dialog, the settings for each load are listed. You can provide a different load description for each load. This description will be used in the circuit.
If receptacles are connected to the circuit, you can make the change in the receptacle schedule or on the individual receptacle. If you change it in the schedule, it will be changed for all receptacles of that type in your project. If you change it for the individual receptacle, it will only be changed for that receptacle. That receptacle will ignore any future changes to the description in the schedule.
Receptacle Project Schedule
Use the “DM Electrical->Receptacles->Edit Project Schedule” command. In the top-right, the “Panel Description” for each load is listed. This is the default value that is used in the circuit description for receptacles.
Use the “DM Electrical->Modify Devices->Query Device” command. Select the receptacle to edit. The information for each load is listed in the top-right. First, check the “Override Schedule Load” toggle. Then, change the “Panel Description” to the circuit description for the receptacle. This description will be used for only this receptacle.
If equipment is connected to the circuit, you need to edit the individual equipment connection definitions. Use the “DM Electrical->Modify Devices->Query Device” command. Select the equipment to edit. The default setting for the “Panel Description” is “Same as Equipment Callout.” When this is selected, the panel description will match the callout. You can select “Custom” to enter a different circuit description for the equipment.
You can add a description to specific circuit. Use the “DM Electrical->Circuiting and Homeruns->Circuiting” command. On the right side there is a “Circuit Loads and Fixed Loads Input” section. Set the “Description” field to what you want to display in the circuit description.
If the circuit does not have any devices connected to it, this will replace the default SPACE or SPARE text for the circuit.
If the circuit has devices connected, the description will be added to the front of the automatic circuit description. It does not override the descriptions that are already there.
Room labels can automatically be inserted in circuit descriptions. To enable this, go to “DM Electrical->Customization->Options->Edit Project List”. There is an “Include room names in circuit descriptions” option you can set to “Yes.” For this to work, the rooms in the building must have be defined using the “DM Electrical->Building Definition->Create Room” command. All of the rooms that the devices on the circuit are in will be listed at the end of the circuit description.
