I'm about a month away from changing the service in my own home. I'm going to insert a section of plastic waterline next to the meter to isolate it.
I'm in Canada and our dirt is frozen for several months out of each year. To me, that means our ground plates will be in ice instead of dirt which probably means a really high resistance. Because our ground, or in the winter, crappy-ground, is in parallel with the poco earth return, we might get a tingle voltage between ground and cement basement floor. I won't be able to measure that because all my neighbors are using the water line as ground. My understanding is that our poco target resistance for their grounding is 5 ohms. Does anyone have any experience with this? (without a Ufer ground, of course)
