Millercarbon has been deservedly schooled here so I’m reluctant to pile on. But he is just so ignorant on electrical circuits and electrical safety!
millercarbonThe two wires in a two wire system, only one of them is hot. That’s your 120V. The other wire is ground. Technically called neutral but this brings up the first redundancy. There’s ground where any voltage potential goes into the actual earth ground. A rod driven deep into the ground. The neutral wire is also ground ...
No, the neutral wire is neutral; it is not ground and that’s an important distinction. Electricity always wants to flow back to the source - not the ground. That’s why an aircraft can have a functioning electrical system even though - obviously - it can have no "ground." But it does have a neutral that flows back to the source.
I don’t by the way have a whole lot of respect or patience for "code". Having learned from a journeyman electrician and having wired a whole house, twice, my experience with "code" is some moron making you re-do a whole weeks work because he thinks you should have an extra 1" of wire in the box. Or 1" less. They are that retarded.
I’ll just echo what others have said here and suggest that you do not know what you are talking about.
I have a friend who is a master electrician. He’s done some exceptional work at my house. He is often confronted by potential customers who want him to take shortcut on a project, which he’ll refuse, citing code. When the potential customer asks what the purpose of the code is, he recites the same two-word answer: "Somebody died."
And that’s exactly how the electrical codes (and other building codes) have evolved.
The third wire, the true earth ground, is merely another redundancy.
No, it’s not redundant and if you understand the difference between neutral and ground, you’d understand that. The third wire is safety ground. The neutral wire is neutral.
So now you know. That’s how I defend my position. By being right. Works every time.
You’ve clearly been shown to be completely wrong on this entire topic and that you refuse to learn reveals much, much more about you than you realize.
