Subject: [RE-wrenches] Derate for # of current carrying conductors

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
