Cable in Gutter Derating
Cable in Gutter Derating
(OP)
I have a gutter installation that has a couple of locations in which more than 30 conductors cross the plane. This requires derating per the NEC. My question is, if I can baffle these areas keeping all conductors in each section <20% fill and <30 ccc (current carrying conductor) can I avoid the derating? What I am in effect doing is creating two gutters within the same enclosure. Thoughts?
