Grammatically and technically you are correct. My point is this.....I know of quite a number of gents who have stole 110 volts off a 220 line for various purposes off a three wire system. I am not contesting your point at all about why a neutral was added. What I am saying is, that you are correct, using a ground for current is not safe and the 4 wire system with neutral eliminates that temptation by providing the supply route for 110. So, in reality it adds safety by eliminating the temptation to use a ground on a three wire for 110 use. That was my point. Oh, sure those electricians would say, that was a stupid thing to do, and they are right, but hey, people do and did things to accomplish what they needed when in a dire situation. If the chickens are freezing you figure something out fast. Not only that, most people back then didn't understand the danger and did it anyway. There were minimal or no codes or rules in many places back then.masonsjax wrote:I don't think anyone is impatient with you. I think this is dangerous stuff that can seriously hurt or kill someone. You're giving indication that you don't completely understand the details that make this dangerous, so yeah, you should be nervous. For example, neutral was not added for safety reasons, that's what ground is for. Neutral allows for using multiple circuits of differing voltage in a single device. Please understand that your (and your family's) safety is our only reason for responding here.
We are here to learn and be safe. And yes, I do understand that the number of amps delivered by 110 volt potential leg of a 220 volt circuit to ground is vastly different than the 30,000 volts of shock I have received on multiple occasions from working on TVs at much lower amps. Especially when circuit is completed to ground via standing in water or touching a grounded water pipe.
Anyway, I do appreciate positive input and hope I can get some input to the objective. I just wanted some input on my schematic. I don't see anything wrong with asking about it and if anyone does I would appreciate your positive comments. And hopefully, this will be a contribution to those who follow this topic. So, if I am misunderstanding the danger and the concept please advise.
