return air wiring?

Is romex / SE wiring permitted to be routed within a return air plenum?

We just went over this in this thread…

Sorry - I missed that previous discussion. However, as usual, there are quite a variety of opinions.:mrgreen:

Yea, I would’nt request removal. I’d simply write it up either way.

In the US, the wiring may run horizontal through that return bay, but may not run parallel with the framing members.
