I was called out for a service to a house that was rewired back in 2007 and it’s an early 1900s house. It’s a duplex on one building one unit on top and one on bottom. There’s still some ridged pipes but mostly Romex pulled and all the wiring is copper the panels look ok. The issue is that the customer is getting shocked by the ground in one section of the house and I also just by touching the metal grounding components of the outlet with the thinner parts of my skin feel a burning shock. They are also complaining that the power surges from time to time and has burned out power strips And also are saying that there is radio towers nearby and can hear the radio frequency coming in from the amplifiers when they play their instruments. I went ahead and tested the lines and opened all the electrical boxes And opened the panels. I found readings on one section of the house outlets the power surge from 122 to 130V I also found When I shut off all main breakers to the both units there is still 30 V my multi meter is reading from the ground to neutral. I did find that the ground in the neutral was bonded in the sub panel but I remove that bond and the problem continues. With all power off When I go to the water pipes my beeping Voltage tester is beeping as if there Was power same thing with the gas lines or even close to the walls and the neighbors fence too another thing I noticed that they had a ceiling that was made out of aluminum or some kind of metal that they put on their ceiling of a bedroom and the problem is in that area of that bedroom. The house has two ground rods semi new panels all the electrical boxes were checked there’s no grounds connected as neutrals and I also called the city to check their neutral connections to see if that was an issue. The problem continues do you feel a shock on the metal part of the outlet that is ground even when you touch it with your screwdriver you’ll see a small spark just by touching it with metal. Is there a possibility that there can be something buried inside the walls and we might need to rewire the complete house again? What should be my next move? One more thing they do have a solar system and I’ve also tried turning that off completely and it’s still 30 V between the ground and the neutral. Maybe somebody with more experience in the field can you give me some insight and help with the situation that I don’t understand.
