Iwire, I agree. One thing we must all understand: ONLY UL gets to speak for UL. Not you, me, the AHJ, Lithonia, or anyone else.
A listing will not be voided if listed, or classified, or recognised, components are used. Whetehr the part is called one thing or another depends on the specifice of the part.
Even if a differing part is used, according to UL, the listing is not actually "voided." It simply enters the "we don't know" category. That is, UL cannot itself say the listing was voided without evaluating the modification.
