Went back to a site where I installed wiring on a new grain storage bin last year and found this communications crap tapped from one of my motor circuits to supply a repeater for the guy's radio equipment
Bet you can guess which raceway wasn't mine.
load end of that run - they ran ENT outdoors (at least on the shady side of the bin) but it will still be destroyed first time snow/ice falling off the roof of bin hits it:roll: They did run the coax cable that is likely good for outdoor exposure in liquidtight flex to antennal on top of bin, did not climb to top to see how that end was terminated.
ENT terminated in a internal type "Carflex" connector with extra securement via a worm drive hose clamp - guess that is only part that may remain intact when it gets some abuse.
Their supply side tap: this breaker is the controller/disconnecting means for a 10 Hp 240 volt auger motor there is no neutral in that enclosure because one wasn't needed for anything (but they tied their 120 volt equipment to the neutral bus which in this case is technically just an equipment grounding conductor, some may say I was wrong to do it that way but it is what it is. BTW the green conductor is going to the motor, the EGC back to main panel is the metal raceway and is also the neutral path for their added equipment. Also the feeder (if you want to call it that) overcurrent device is also a 90 amp breaker and tapped to it is a 14 -2 NM cable, wrong black/white polarity plus they never used the bare EGC in their cable, and pulled through the ENT.
Inside their equipment enclosure, they land in a 5-15 receptacle - I did not take it apart so who knows what else they did in that.
Though not as big of an issue as most of what else they did, I wouldn't have put the hinge of the NEMA 4-12 enclosure on the bottom, no matter what it falls open if you forget to latch it and lets the elements in.
Edit to add: only overcurent protection for that 5-15 receptacle is the 90 amp breaker back at the main panel on opposite side of the bin.
