I recently had the chance to demo the hack electric work one guy did in his industrial rental space. These two pics, taken in the bathroom, are a good example of his technique.
It looks bad enough without opening the wall.....but, behind the wall, our friend decided, halfway through the job, that he really didn't need EMT after all. He continued the wires through the wall/ceiling spaces, then connected them to the boxes with two-screw clamps.
What he needed was one of those new conduit stretchers. Greenlee is currently designing a version that is good for EMT and PVC.... I'm told you'll be able to pull about 3"-4" out of a ten foot stick of EMT and 6"-8" on PVC...on a warm day.
The presence of two red wires would indicate the idiot factor was quite high the day this circuit was installed. Hey at least he put a cable clamp on the box with those red wires. Yikes!!!
Why is it that more stuff doesn't burn down due to stuff like this.....and would the insurance company pay out if it was related to something like this. I'll have to check my homeowner's policy for a 'DUH' clause.
