You can change how your feeder IDs are formatted in the project customization options.

Ribbon: DME/DMERT: Customization->Project Customization->  Options

Pulldown Menu: DM Electrical/Electrical RT->Customization->Options->Edit Project List

In the One-Line Diagram section, find the Feeder ID format option and set the format you want to use. See Feeder ID Formats for more information about the different formats.

If you change your feeder ID format at the beginning of a new project, you don’t need to do anything else — when you create your one-line diagram, feeder IDs will be generated based upon the selected format.

If you change your feeder ID format during a project, some additional work is required to change the format for existing feeders:

1. After you have changed the feeder ID format, run the Feeder IDs command.
   • Ribbon: DME: Customization->Project Customization->  Feeder IDs
     DMERT: Customization->Project Customization->Feeder IDs
   • Pulldown Menu: DM Electrical->Customization->Feeder IDs->Edit Project List
     DM Electrical RT->Customization->Feeder IDs->Edit Project List
2. Press the Delete Multiple button. The Delete Multiple Feeder IDs dialog box will open.
3. Select all of the feeder IDs in the list and press the OK button.
4. Press the Exit button to close the dialog box.
5. Run the Update command.
   • Ribbon: DM Electrical->One-Line Diagram->  Update
     DM Electrical RT->One-Line Diagram->  Update
   • Pulldown Menu: DM Electrical->One-Line Diagram->Update
     DM Electrical RT->Update One-Line Diagram

The feeder IDs on the one-line diagram will be redefined based upon the new feeder ID format.

Troubleshooting

Q: I followed the instructions, but my feeder IDs either didn’t change or changed to something different than the format I set. What happened?

A: This can occur when your project pulls feeder IDs from the master schedule. There are two solutions:

• In the One-Line Diagram section of the project customization options, find the Transfer feeder IDs from master schedule if possible option. Set this option to No and press the OK button. Then repeat the steps above.
• Perform steps 1-4 steps above, but run the master Feeder IDs command instead. Then repeat all of the steps above as written.
  • NOTE: Do not delete feeder IDs from the master schedule unless you’re sure they won’t be used for other projects.
  • Ribbon: DME: Customization->Master & Standards Customization->  Feeder IDs
    DMERT: Customization->Master & Standards Customization->Feeder IDs
  • Pulldown Menu: DM Electrical->Customization->Feeder IDs->Edit Master List
    DM Electrical RT->Customization->Feeder IDs->Edit Master List
