Having the “UL” in a circle molded on the plug will help to identify that the complete PSC is ULcertified. Users of a PSC where the flexible cord bears the UL Mark could easily assume that thecomplete PSC is UL Certified, when, in reality, only the flexible cord is certified. It is importantthat users of PSC can clearly identify that the PSC is UL Certified, especially after the packaging,including the holographic label, has been removed.
