see that on services quite a lot. some times i work on farm customers pto generators. i don't sell them, but i will come in the middle of the night. hogs die without ventilators. pays really well. i've learned to stand on a milk crate and bond to the ground rod with my jumper cables. there is a lot of junk on farms. worked on a factory, once. put a amprobe on grounding conductor. north of 10 amps to ground. their in house maintenance people were going to just unhook it. i talked them out of that. i was putting in airlines. i changed out a service lost fall, was a residence meter tub, riser, some of the potable water piping had 120v flowing in it. ungrounded metal buildings with the skin hot. lol. although it's not really funny. i work over on the dark side so i just grab the wires to see if they are hot. please don't do that. there are circuit testers greenlee gt-11, etc. what they will do is tell you if you have a problem, then you can deal with it or call me. breid............:party-on:
I've seen in too many older houses where the only real ground was at the water service entrance. They figured the water pipe in the ground would serve well. What they didn't think about was what would happen during plumbing repairs.
You would do well to strongly recommend an electrician upgrade grounding before someone really does get zapped.
Well, scratch that theory. I came accross older commercial buildings fed with the old corner ground Delta systems where I damn near gotten belted off the ground wire upon reconnection. That was one hell of an arc that was created as I trying to rebond to the panel grounding bar.
