I-Line 225–600 A Busway

I-Line 225–600 A Busway Catalog Numbering System

Catalog numbers are composed of two basic parts—the prefix (shown below), plus the suffix of each individual busway component from Straight Lengths through Flanged End Details.

The prefix contains necessary busway information except individual component descriptive details that are defined as the suffix. The catalog number prefix will generally remain unchanged throughout a busway run while the suffix will vary with each individual length or fitting selected.

A few devices, such as hangers, wall flanges, etc., do not follow the exact pattern described above. For these exceptions, a complete listing of device catalog numbers is shown with the individual device drawing(s) in Cable Tap Boxes (Plug-In) through Required Wall and Floor Openings.
