can you use a gutter as a raceway? given a six inch by six inch gutter mounted horizontally on the wall is it permissible to install a conduit into one side (bottom) and then exit opposite or at any other location on the top side routing the conductors or cable through the gutter then back into the conduit?

i was told by an electrical supeintendant on the job that this would be a violation...i disagree.

please tell me what you think....
