Re: Metal staples
Back when I was a fresh and green first year apprentice, I got an opportunity to perform a "hot check" with an experienced electrician on a few units on a multi-family project.
We came to one circuit that was instantly tripping the breaker when switched on. Knowing how each unit is wired, the electrican disconneted the feed in to the first outlet to see if it was down line or in the homerun. As it turned out it was in the non-accesible homerun cable. (NM)
The electrician then instructed me to go down to the work trailer and get him a two-pole 60 amp breaker. Totaly lost and confused, I did what he said. When I got back, he explained to me that the rough-in crew was notorious for hammering the romex staples in too hard on the cables.
He then proceeded to connect the circuit to the 60-amp breaker. He switched it on and POP, did it again and POP! On the third try, it held. He then connected the circuit back up to the appropriate breaker and with a slight chuckle stated, "took care of that staple".
Knowing what I know now, I get sick to my stomach everytime I think of that day. This person was responible to ensure my training, and the electrical integrity of that unit.
I wonder where that guy is now. If you are on this forum, I hope you reading this from jail!
