Hey Wrenchers, Is the derating for the number of current carrying conductors inside a large trough the same as it is inside of a conduit? Seems to me that if for example a 8" x 8" trough is used for 9 current carrying conductors the derating should be less than if it is inside the minimum size conduit for the same 9 conductors.
Thank you for any and all feedback! Al Frishman AeonSolar (917) 699-6641 - cell (888) 460-2867 www.aeonsolar.com
