    Mounting a Plastic Single Gang With Screws INSIDE of box

    Basically, I had to work in a condo and one of the boxes was mounted backwards in a tight section and already had wires spliced in it. This is a Loomex woodframe project with plastic boxes. To get the box properly oriented, I had to clip some of the plastic on the box. When I finally reoriented the box, I noticed that the side mount no longer had a place to screw it into a stud and since the wires were spliced I couldn't flip the box. So I put a screw inside of the box into the stud. I put some electrical tape over the screw, but I don't feel right about leaving it like this. The only thing I can think to do more is either

    A)pigtail the bond and bond the screw
    B)unsplice everything, throw the box away and replace it with a new box, possibly damaging the wire insulation in the process.

    It's good that you feel bad about this. It shows you have character. That said, I think everybody has put a screw through a plastic box at least once in their career. For some people it's once a week. I wouldn't sweat it. (Now if it was a metal framed wall, that would be another story.)

    They have gone a little too far with rules here IMO. If that screw into wood framing should become energized - so what?

    Time to start installing bonding jumpers to wood framing I guess

    Maybe should bond the non metallic boxes as well.
    I live for today, I'm just a day behind.

    I have done work in old houses with crappy plaster or nasty drywall. I would always cut in my plastic old-work boxes near a stud, if at all possible, so that if the sheetrock or plaster started cratering I could screw the box to the stud for support.

    Put some duct seal and/or duct tape over the screw.
    They say I shot a man named Gray and took his wife to Italy
    She inherited a million bucks and when she died it came to me
    I can't help it if I'm lucky

    By golly, there's actually a code for this! '17 changes inbold

    314.23 (B)(1) Nails and Screws. Nails and screws, where used as a fasten‐
    ing means, shall secure boxes by using brackets on the outside
    of the enclosure, or by using mounting holes in the back or in
    a single side of the enclosure
    , or they shall pass through the
    interior within 6 mm (1∕4 in.) of the back or ends of the enclo‐
    sure. Screws shall not be permitted to pass through the box
    unless exposed threads in the box are protected using
    approved means to avoid abrasion of conductor insulation.
    Mounting holes made in the field shall be approved.
