Who Does This ?

I started out at a large slaughterhouse that had a lot of vibrating machinery including crushers, hammer mills, huge cookers, shakers , vibrating screens for water pollution etc. You had to apply several layers of quality tape on every pressure connector ( yes wire nut ) or else they would come loose. Even had to watch splices inside of motor pecker heads. We installed at least a dozen layers of scotch cambric tape followed by lots of black tape. On a few high vibration crushers we had to install dozen wraps if silicone or rubber tape between the cambric & black tape due to vibration cutting into bugs. On motors above 25 HP usually used grade 5 bolts along with flat washers and quality lock washers to prevent loosening. Never reused lick washers on motors. Tape also keep things working because so many boxes had water in them due to nightly cleaning with high pressure washers. Finally went around and drilled a 1/8 to 3/16" holes in bottom of at least 40 start stop buttons to allow water to drain out.

I can understand and have an appreciation for taping wire nuts in motors that vibrate. Light fixtures don't vibrate though (at least not any that I've seen recently) :cool:

  1. Who brings NM cable into a fluorescent light and then bends the EGC back through the connector in order to establish a ground ? It might be understandable if the fixture didn't have a grounding screw OR if the connector wasn't installed in a removable piece of the fixture.
  2. Who bends a solid wire over and then wraps the fixture wire around it so that a yellow wire nut will stay connected to the wire ? Why not use the right size wire nut ?
Just sayin' :cool:

1. someone trained by someone that is not a real electrician?

2. Yellow wire nut probably been used before and spring is stretched enough it won't accept smaller group of conductors it had been stretched out to accomodate. Otherwise a new yellow will typically work with just two 18 ga conductors
