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.
