    Damp Area Junction Box

    Damp Area Junction Box

    New postby Jimmy_B on Fri Mar 15, 2013 8:34 pm

    Hi Jerry,

    I'm working on changing a light fixture attached to the ceiling of our front porch. The existing fixture has a drop down glass cover and is not attached to a junction box. It is mounted directly to one of the support boards that frame out the porch. I am able to get to the fixture from above via the attic and noticed that the fixture has about a two foot length of metal conduit coming directly out of it and running to a juntion box that then changes to romex and on the the switch box down below.

    My question is what type of juntion box do I need to install to this damp area so that I can hang a new outdoor fixture? Can I use blue PVC or a regular metal ceiling box in this area? Also, can I run romex directly to this new box?

    Thank you,
    Jimmy B.

    No to the above being a damp location and, yes, you can use ...

    ... either of those.

    Yes, provided the box is designed and listed for NM cable (has proper cable clamps) or a box with knock-outs for conduit where you can install a cable clamp into a knock-out and the NM can go in through the clamp.

    The attic is not a damp location, the space under the outdoor ceiling area of the porch will either be a damp location or a wet location, with the area up at the ceiling typically being a damp location - so make sure that the fixture you purchase is damp location listed (will have a sticker or label stating "Damp Location Rated" or similar).

    The fixture should be ... is required to be ... attached directly to the fixture box and not to the attic framing or the ceiling framing, and if the ceiling is combustible (such as wood) then the face of the box is required to extend to, or project beyond, the surface of the combustible material - the face of the box is not allowed to be recessed any amount at all behind the surface.
