I am living in an apartment and suddenly we started to get an electric shock, at random, when touching a water tap. Since I am an Electrical Technician, I started
my research on the origin of the problem, and after carrying out a series of tests I found out 'at the end' that turning off all the breakers (in the breaker box) and measuring the voltage between each hot wire and the metal box surface I got a full 120 V reading! The other tests I made were the following:
1- I turned off all the breakers and then turned each back on, and then off, sequentially and measuring the voltage at the corresponding outlet. In all
the cases I got a full 120V between the water pipe and the hot wire at the outlet. With this test I wanted to verify any leaking voltage of each breaker line.
2- When testing the heater line (turning its breaker on), I found out that there was a 90 V reading between the hot wire and each of the two ends of the
water heater resistance; of course, after I set apart the cables.
So, the only clue I have is the breaker box-to-hot-wires voltage, and I wonder where and how the water line and the electrical metallic conduits shake hands. Any help?
Thanks
I was not really sure whether to add comments to my previous post regarding the problem I reported, since it was closed with not right to reply and suggesting the get an electrical technician. In such cases, I would suggest the Administrator of this site to leave the door open, so the poster could reply whether or not he has solved the problem. In my case, I did solve the problem by myself and I am an Electrical Technician... Anyway, just for helping the audience with similar issues, "the problem was caused by my old refrigerator(1) and it was solved by swapping the electric plug position: the plug-outlet hot and neutral position must coincide." The electrical shock existed because the fridge's inlet water valve is connected to a copper tube and this to an external water filter. So, having a faulty fridge electrical issue, it explains the electric shock. I was really worried about the high life-threatening risk I was on, but it is luckily over.
