- I am feeling unpleasant electric shock when I touch metal water pipes or faucets.
- This happens also when the main breaker is off (L1, L2 and L3). This rules out my appliances (hot water boiler and etc.) being faulty.
- From my understanding, the two remaining sources of electricity could be:
- Neutral wire
- The soil itself (as in something big nearby is leaking)
- When measuring the voltage difference between soil and neutral wire at the inlet, it reads 10-20V volts.
- The house doesn't have its own grounding. Grounded appliances connect to the neutral wire at the breaker box.
- European power grid
Questions:
- Are my assumptions correct?
- Is there a way to find whether it's the neutral wire or soil that's responsible for the issue?
- Any way to mitigate this issue?
