That is why Fletcher states that a 3" plastic conduit would require nailplate. Being that it only allows for 1" of clearance to the stud face. Even if center perfectly.

Correct?

So basicly I think I am in good shape. Use CMR rated cable, Use electrical conduit, not white pvc, Low voltage boxs are ok. Use firestopping caulk at top/soleplates, and firestop the 3" conduit at the openings with "putty".

Thanks again you all for the great help. I am probably more adventurous when it come to this stuff than most people. But with help like this I think I am in good hands.

So if I am wrong about any thing let me know before I hold up my construction because it dosn't pass code.
