How do you figure? Where did you come up with this misinformation?there is a concern it that if there is a bad connection (Break) in the Neutral somewhere the Neutral would become live creating a short circuit (hopefully blowing the fuse )

This discussion should be an eye opener.
I feel the same. That's the main reason why I opened this topic.
So it is the result of an old translation error.Difference in Terminology:
In USA term Grounding is used but in UK term Earthing is used.
What Toyota really meant was “connect it to the chassis”.Evo said:But in English the term is GROUND not Earth. I remember years ago my Toyota car manual said to EARTH one end of a connection. They meant GROUND one end.
Yes, that was the case.What Toyota really meant was “connect it to the chassis”.
Thanks!Ground is ground. It's a question of "what" ground. Here are the symbols:
Yes, and they call cookies "biscuits" and french fries are "chips".Yes, but I believe in Britishese, the term is "earth".
Do you mean Us Navy ships have delta connected gen? As i understand ships normally have Y gen with isolated neutral. High voltage 6.6 kv ones are earthed with a high Resistance.The answer is nothing, provided that everything was properly wired and that the power source generator was grounded. This covers most cases, but certainly not all of them.
With a Y-connected generator, it is easy to ground the center of the generator, and it is common practice to do so. With a delta-connected generator, there is no center point, and consequently such systems often have not grounded neutral (the happens in the US Navy in places).
If in doubt, measure the potential between the two wires before you short them.
I know there is a move to standardize both the terminology and equipment (wire colors, etc.) internationally. It's not my field, so I don't know how far along it is or what the changes are.Thanks all of you, I was wondering if terminology had changed or if it was just that 40 years ago I was only exposed to American books and with the internet, terminology became mixed, it seems the latter is responsible for a lot of the mixed terminology I see now. This is what happens when you stop learning and then pick up after 40 years.
