Ted,
In order that your company NEVER have any problems with
this issue ever, you will have to follow NEC 645-5 to
the letter. Ultimately, it's up to the interpretation
of the local inspector.
Having been called on the rug about this very issue from
just one customer within the past year, my *suggestion* is:
Do NOT put ANY power cords under a raised floor no matter
if it's a plenum issue or not and no matter how long or
short that power cord may be - none.
Unless of course you can procure the style power cord
required by the standard. And good luck with that.
