What does the suffix "GRA" designate in a busway plug-in unit, for example, PQ3603GRA?

Issue:
Selection

Product Line:
Busway

Environment:
UL 857, CSA C22.2 No. 27-1973, NFPA 70 Art. 368

Cause:
In most circumstances it is necessary to fully understand the features of a busway plug-in unit which are designated by the suffix(es) added to the standard published catalog number.

Resolution:
The ``G``designates the ground provision, which is now a standard feature on busway plug-in units (and is removable if necessary).  The ``R`` designates factory installed Class R fuse rejection clips.  The ``A`` suffix designates special lugs, most often a copper compression lug, unless otherwise specified by the customer.
