I'm reading this thing and
1. Read 645-5 one way and it might be read
to require ANY ITE equipment on a raised
floor environment to have DP type cables.
As in the second to last para that states
"Section 645-5(d)(5) requires interconnecting
cables used under raised floors (other than
branch-circuit conductors) to be listed as
Type DP cables ..."
2. Read 645-5 another way (which is the way I
think I'm supposed to) and all ITE equipment
on a raised floor environment are covered
as long as they comply with 546-5(b)(1),(2),(3)
prior to the above quote.

Q; Could someone please provide their own
*interpretation* as to how this section
of NEC impacts ITE equipment on a raised
floor environment with regard to SO or DP
style power cables?
Q: Does UL-1950 3rd Ed. in fact require
DP style power cables for ITE equipment
on raised floors?
I thought this would be an issue if in fact
an electrician was hard wiring the power cord
of an ITE product that was on a raised floor.
And as long as the electrician is NOT hard
wiring the ITE product (even though in a raised
floor environment), then compliance is covered
under Section 546-5(b)(1),(2),(3).
