    Default Panel location

    Would this basement electrical panel install be considered a wet or damp location since its mounted on a block wall that is not underground were its installed ? Panel does not have plywood behind it to create that 1/4 air gap- space from the wall that's stated in the IRC 2012 code book (this county is going by the 2012 code) ??

    Sam,

    Most surface-mounted panel enclosures that I have seen have little dimples that hold the rear wall of the enclosure away from the wall. It kind of looks like there is a small space between the panel and the block, but I can't tell for sure.

    If the wall does not get wet, then it seems to me this is not a wet location.

    The required space is built into the panel back.

    See the NEC for the definition of location, wet and location, damp.

    Can the CMU wall become damp or wet.
    Typically, I see boxes/enclosures mounted on plywood substrate secured to CMU.
    312.2(A) requires the gap, at least 6mm/1/4" inch, if it is in a damp/wet location.
    This a crawlspace?

    Cables are not installed correctly. Article 334.30 states: secured within 12" inches of the box/enclosure, equipped with cable clamps.
    Exceptions. 314:17(c) nonmetallic boxes, to which the image is not.

    A better photo (higher resolution and better focus) would help.

    I think I see the standoff mounting dimples which space the back of the enclosure 1/4" out from the surface of the wall ...

    ... and I think I see greenish/blueish concrete fasteners installed NOT IN THOSE LOCATIONS ...

    ... which pulls the back of the enclosure tight to the wall.

    Off question, but I agree with Robert: Quote

    Surprising (not really) that two HIs called out, and gave a code reference for, not properly secured, but neither called out the not maintaining spacing (actually full blown bundling).
