That's just so ridiculous!!, under anybodies Codes, this piece of metal, being exposed to touch, should have been bonded to Earth. I hope that this keeps, the person who installed, this shoddy poor excuse for a job,awake at night, knowing that he has killed an innocent child!!.

Trumpy, Bonding to earth will not solve the problem. It must be bonded back to the grounded conductor at the service equipment to clear the fault. The earth is too poor of a conductor to really help prevent injury or death. Has anyone ever seen a bonded box cover in an installation of this type? I never have. Don

Don: We use "quazite" boxes only. They are a cement/fiberglass combo (I think) and they have a cover of the same material. Personally, if I or my guys "had to use the cover to push the conductors into the box" we would know that something was WRONG. No way in hell would we leave any "hot" conductors touching a metal cover, or any other cover.
As to seeing a cover "bonded", yes we do install bonding jumpers on enclosure doors, and large hinge cover pull/splice boxes. It's our MANDATORY practice, and a "spec" by some of the PE's we work with/for. I can't say that I've seen a jumper on the type of installation described in the article. You may have me looking now, but the majority of metal cover boxes are utility owned & maintained.
Anyone know the date of this horrible accident???

We also use the "quazite" for some of our underground installations. The boxes that I have seen with metal covers have been in sidewalks for street lighting and traffic lights. Some are utility owned, others are owned by the cities and were installed by electrical contractors. I have never seen one of these with a bonding jumper to the metal cover. Up until 2 or 3 years ago, the State of Illinois did not even use an equipment grounding conductor in traffic signal circuits, so even if someone wanted to bond the cover there was no way to do it. That has changed now, but they did not go back and install EGCs on the existing equipment. Don
