I had two exterior step lights installed in front steps. The concrete was poured but the masonry contractor forgot to connect the grounding wires. How do I make it safe after the fact? They are 120 volt lights inside light boxes

    Usually wiring through poured concete is in conduit, often ENT. Pictures of the inside of these light boxes, please? Turn off the breaker first, of course.

  • The implication of Ecnerwal's comment is that the ENT itself may be the ground - that's why the request for pictures of the wiring in the box. Also, if there are ground wires then it's a simple fix to connect them to the fixture itself.

    @Freeman EMT would qualify but ENT is Electrical Nonmetallic Tubing. Alphabet soup lol. Nov 17 at 18:13
  • oh. :( Would like to blame lack of coffee, but I'm sure I'd had a couple by then...

  • But if it's ENT (smurf tube) (as is common) adding a ground should be relatively easy if the conduit was contructed correctly. OK, now to see if I can manage to take a vacation from spending too much time here, having ticked the 200K box for real. ;^) (and still no T-Shirt...)
