Not that I like to mark words but it´s more correct to say "between
one phase and neutral". The neutral is also grounded but at the
distribution transformer side.
Yes. It is always important to understand the difference between neutral
and ground. Neutral usually carries load current, ground must never
carry load current. The only function of ground is SAFETY. In most
countries, the "ground" wire must be connected to the chassis, and is
there to blow a fuse or trip a breaker if the chassis becomes hot
through some fault. In nearly all countries, neutral is connected to the
ground wire, but WHERE and HOW it is connected varies widely from one
country to another. In North America,.neutral must be bonded to the
"green wire" (ground) where power enters a building, and again at the
secondary of any transformer.
