Is it acceptable to install a contactor inside a wire trough with other conductors? Im not speaking of service gutter. There is a separate trough inside building used as raceway for other wiring.
It comes down to which came first, the trough or the contactor. You aren't running wires through an enclosure for a contactor, you are putting a contactor in a raceway that already has wires.If you were to ask me whether it's okay to run wires through an enclosure that contains a contactor, I'd say,"Sure."
