Interesting. I checked one of our ITE UL reports from 1997 and the general
section requires shipping either a UL Listed power cord or an acceptable
cord when shipping outside the US. What do others have to say about this?

Richard,
It has been a few years now that for ITE, NRTLs do not require a
detachable type power supply cord to be shipped with the unit. At
some point, they required that for units not provided with
detachable cords, a non-permanent marking be provided by the
power Inlet "See Installation Instructions for Proper Selection of
Power Cord" or an equivalent marking together with the relevant
instructions on the proper power cords to be selected in the field.
However for some time now, this requirement has been dropped
and provision of a Listed and/or Approved cord set is optional.
