I was forced to deal with about 20 of them in a grocery store remodel. Somehow the original installer got away with setting them in the concrete floor with the PVC cover flush with the floor.

The store manager was getting tired of replacing the covers after a shopping cart cracked it or one of the pallet jacks fell thru it.:laughing:

I had 1/4" thick stainless steel diamond plate covers made for the boxes and set them all in place. That's almost four years ago now and not one broken one yet.

We use them all the time.

If it lands in a desert landscaped space, we just install them an inch or two above grade. If there is traffic, we put the appropriate box over it.

Had no choice but to bond them to ground. Had a 1/4" stud welded on to each cover plate......ran a #10 green with a ring terminal on end from the stud to the egc that was running through each box. IIRC, connected that end of the #10 to the egc with a split bolt.

It is a pain in the ass coiling 8' of #10 green back into the box every time you remove the cover for service but..........
