Hi all,
Sorry for a late reply but I have a good story to go with this post.
I was the main electrician for a large manufacturer, I got called because a field service guy said sparks flew and he melted the tip off of one of his test leads. He was checking low voltage on a communication cable between sections of a piece of equipment. I got there within a few minutes of the call but EHS, security, managers you name it were already
there. So I started checking and could not find anything to explain what happened, I kept asking questions and found he used a 4 sq. box with a receptacle as a ground source. the box had no damage but I pulled the cover and saw what happened. He was not looking when he put the lead on the box and stuck it in one of the manufactured holes and hit a live terminal on a twistlock recep. Thought someone was going to push for taping the receptacles but never said anything.
