Working with Sequential Feeder IDs

Thursday, July 25th, 2019

Unlike other feeder ID formats, which are generated based upon various properties of the feeder, sequential feeder IDs are generated simply as a series of numbers ordered by ampacity and when they are generated. You can use the feeder schedule (Electrical / RT) to see which feeders correspond to each ID.

As you work on your design, new feeder IDs are added to the end of the sequence. For example, if you draft 100A, 200A, and 150A feeders all at once (labeled “1”, “3”, and “2”, respectively), then add a 60A feeder later, it will be labeled “4”. The IDs for the existing feeders will not change.

Once your initial design is ready for publishing, we recommend deleting and redefining all of your feeder IDs so they will be nicely ordered. Using the example above, the 60A feeder ID will change to “1”, the 100A to “2”, and so on.

When preparing to publish revisions, we recommend not deleting all of the feeder IDs. This will cause the IDs for your original feeders to change as well. Instead, only delete those added during revisions; this ensures the new set of feeder IDs will be in order without disrupting the original set of feeder IDs. For example, if your initial design has feeder IDs 1-15, only delete feeder IDs 16 and up.

Using Custom Feeder IDs

If you’re not happy with the built-in feeder ID formats, you can create your own custom feeder IDs.


Turning Off Feeder IDs

You can turn off individual feeder IDs in the one-line diagram with the Change Graphics command, or disable feeder IDs entirely in the project customization options.


Inserting Feeder IDs for One-Line Diagram Users

Previously, Feeder IDs needed to be inserted manually; beginning with Design Master Electrical 8.4, they can now be inserted automatically by having this customization option enabled.


Changing Feeder ID Formats

Changing your feeder ID format at the beginning of a project is simple; changing it mid-project requires deleting and redefining existing IDs.


Changing Feeder ID Block Graphics

The block used for feeder IDs can be changed in the Edit Feeder ID Group Settings dialog box in the Feeder IDs customization command.
