Just a quick question. Is it safe to run a 110 12-2 that is weather rated down the length of the trailer by way of AC duct in the ceiling?

Never thought of this but I don’t see why not.

I have done my runs from underneath and then up through the floor or some other natural opening.

curios what you are powering?

Safe? No. It is not plenum rated. https://sewelldirect.com/blogs/learning-center/understanding-plenum-and-other-nec-cable-ratings

Can you imagine if a mouse got in, chewed the insulation off the wire and then it shorts. The airflow thru the duct when the AC is running will feed a fire like a blast furnace. This I would never do!

Gaffer’s reply in post #3 is correct, this is not plenum rated cable.
