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.
