    Thinking of framing my basement in PT lumber (I've seen what decades of basement moisture does to framing). I'll be running MC cabling because I'll have foam insulation up against the outside walls. My question is, are there grommets of some kind (presumably of plastic) that I can use to protect the wires when they go through the PT lumber?

    I guess an alternative is running PVC conduit but (a) it's a lot of conduit and (b) on the wall where the circuit panel sits, there would be a lot of conduit.

    I don't think pressure treated lumber has formaldehyde in it. HCOH is found in plywood, carpet, probably laminatedbeams, etc. PT has stuff a lot worse for you than formaldehyde, but not very air mobil.

    If you need PT studs for the walls, then you have a bigger issue than what kind of wires to install.
