Just over one hundred years ago, the subject of grounded vs. ungrounded Neutral was debated in North America and other parts of the world.
In most of Europe, the standard is 220 Volts 50 Hz with both sides of the line ungrounded (there is no neutral).
In North America, there are a bunch of standards, e.g.:
1. Split phase 240 Volts with 120 Volts each side of Neutral.
2. "Y" connected three phase 208 Volts with 120 Volts from each hot leg to Neutral.
3. "Delta" connected three phase 240 Volts with no Neutral.
There are a few other obscure US standards.
The safety debate still goes on and on and on …
