This "interpretation" is news to me. I thought that the derating was based on requirements of the NEC and was specifically addressing the power plug (plug cap) itself.

Kelly, UL 1950 has a D1 (more restrictive) deviation in clause 3.2.1: "Where equipment is intended to be connected to a source of supply by a power supply cord, the attachment plug shall be rated no less than 125 percent of the rated current of the equipment." UL's interpretation of "attachment plug" includes not only the plug that goes into the wall outlet, but the entire path between the wall outlet and your power supply, including: * Wall plug. * Cordage. * IEC-320 plug. * IEC-320 appliance inlet.
