First days as a apprentice in a slaughter house the chief electrician told me to tape every wire nut, toggle switch & receptacles with quality electrical tape. Reason being water intrusion & vibration were a major problem. Rather spend 25¢ of tape the have a wire nut short out then produce down time that could cost $1,000 in lost production. While working in the same room with a union electrician he was just saying we wasted time & tape wrapping every device with tape then whi!e he was installing a HG TR GFCI receptacle in a old work box he shorted his non taped receptacle to one of the Madison bars. Was funny watching the deer in the head light look on his face. Told him that I would give him a roll of Scotch 33 tape to use. Have a bone to puck with " ground I g does not matter much ". I had a lazy cut every corner always in a hurry senior electrician had the same believes until he was called out to reinstall two lengths of 11/2" EMT back into a coup!ing that he installed just a few weeks earlier. He was too lazy to install a copper group wire and only halve the required straps on a 480 volt line. Wire got nicked and when the nicked wire came into contact with the ungrounded conduit current went thru both bare hands thru his chest. He had chest pains rest of the day and the nurse to!d him sit in her office rest of the day. After that he installed copper ground wire in every conduit. Better safe then dead! Facility director was not happy when he found out that he was not installing ground wire in every conduit. In the USA we loose an electrical worker every day due to electrocution, Arc Faults or Arc boasts incidents. Anything going beyond the NEC that helps lowering injuries or deaths is worth the time & material cost.
