Most of Norway has traditionally had a Y 230. but the center point has not been bonded to ground, so it has usually not been a neutral at all. New transformers for new buildings use the more common European system of 400/230V Y, quite similar to the US 480/277V system. It has been some regional differences, The Stavanger area used the 230/400 (Earlier 380/220) system, Arendal area used a grounded center on the 230y but no Neutral wire in the supply system.

One other thing the NEC allows [ 250.130(C) ]is running a independent ground wire, such as a #10 AWG green, back to the grounding electrode system. This can be a good option when the ampacity of the branch circuit is sufficient for the load and you just need a grounding type receptacle, such as a old 3 wire NM 10/3 cable for a dryer can be converted to a 4-wire NEMA 14-30.

Yes, that was a joke. I figured that if the Canadian dollar has a lesser value than the American dollar, it followed that the Canadian volt was smaller than it’s American counterpart.

The above post links to a site that asks for your credit card before accessing the “free” information. I advise against it.
