A location box is drawn around devices to designate that they are physically in a different location/installation than the other devices in the drawing. The box is a closed polyline and can be a rectangle or some other orthogonal shape.
You have the option to update the location and installation codes for the parent components within the box to match the location box. You can assign a description to the box.
The Location and installation codes for the parent components within the location box update to match the location box. You can assign a description to the box. The program prompts for updates to related components and panel footprints.
AutoCAD Electrical toolset commands are location box aware:
AutoCAD Electrical toolset circuit commands are not location box aware. For example, if a circuit is inserted and some of the components fall within a location box, the components are not updated.
The layer assigned to the Location Box feature determines the color and linetype of the polyline. Assign the layer on the Drawing properties: drawing format tab dialog box.
