Mike,
Back in my days as Compliance Engineer for AT&T Global Information Solutions
(NCR), I was successful in obtaining UL/CSA waiver for production line hipot
testing of the end product on the basis of using a listed power supply that
had already been subjected to hipot as a part of the power supply
manufacturing process. Hipot was still required as a part of the UL/CSA
evaluation for initial listing of the end product.
Ground continuity testing was still required due to the fact that the
mounting of the power supply in the end product established necessary
contacts for ground continuity.
