    Mixing ac and DC conductors in a gutter or trough

    Thank you in advance

    I have been installing inverters for the past 7 years with a gutter or trough below them. I have just been called on not being able to do so. I have always identified these contractors.

    I remember a while back seeing a photo of the situation and allowing it. Can anybody direct me to this I would really appreciate it

    Thank you again

    The inspector is correct. See 690.31(B). Now wireways are not specifically in that list, but seems pretty reasonable to me that they are covered under the "or similar fitting" provision. Are the conductors organized in such a way that you can put a divider in?

    It changed in the 2014 NEC and you can do it but you have to use a partition.
