Even my horse learned not to touch an electric fence after 2 attempts...
A contractor friend has calculated that his losses THIS YEAR ALONE exceed $100,000 from copper theft. He built a set of power and control trailers for rock crusher operations., Theives cut the locks and removed the bus bars from MCCs and switchgear, then cut all of the portable cords used to connect mobile equipment.
In my opinion the removal or ground equipment or other safety related systems involving electricity should be considered attempted 2nd degree murder! Or at the very least, willful disregard for public safety, maybe even industrial terrorism. Then the scrap yards who buy this stuff from questionable sources could be held liable for aiding and abetting.
