Functional Groups
A functional group is a collection of electrical equipment that can be grouped together under very specific conditions. Functional groups are created, edited, and deleted from the Database focus. You can plot TCC curves for functional groups in the Coordination focus.
Currently, the only functional group that is available is the Relay Controlled Fuse Group
Functional groups are only available if your system is set to ANSI short circuit calculations.
Creating a Functional Group
To create a functional group, all of the equipment required by the group must be selected on the one-line. For a relay controlled fuse group, this includes the controlled fuse, switch, and relay.
- In the Database focus, select all of the items needed to match the group requirements, right-click on a blank area on the one-line, and then click Functional Group.
- Select the functional group type you want to create. If any required items are missing from the group, you will be warned.
For more information about the requirements of the relay controlled fuse group, see Relay Controlled Fuse Groups.
Editing a Functional Group
To edit a functional group, in the Database or Coordination focus, right-click on a required item in the group, and then select Functional Group > Edit.
These settings are used when you plot the functional group in a TCC in the Coordination focus.
Deleting a Functional Group
To delete a functional group, in the Database focus, right-click on a required item in the group, and then select Functional Group > Delete. You are asked to confirm the deletion.
Deleting a functional group does not remove the items from the one-line, it merely removes the functional group from the items.
If you delete an equipment item that is part of a functional group (such as the controlled fuse, relay, or switch), the functional group is also deleted. If you delete supporting equipment that is required to make the functional group valid (such as the main fuse or the downstream bus), you will receive warning messages regarding this when you enter the Coordination focus.
