08-28-02: Bigtee Audioengr--- well, I didn't get to talk to the EE's here at work today, duty called. However, I will. I still don't understand this so I will get one of my troopers to explain it up close and personal. With house wiring, the neutrals are connected straight to the buss bar in the breaker panel and and connected to earth ground. I still don't understand your previous analogy of the battery and bulb since DC does flow in one direction period. And you do have positive and negative on DC. There is no such thing as positive and negative on AC which it would have to be. The return would be negative. As I said before, you have the positive half cycle and then the negative half cycle that "Flows" the opposite direction on the same wire. In an Air Conditioning unit you have a step down transformer usually 120/230 to 24 volts. On the output of the secondary, one side is tied directly to earth ground and also serves as the common for the wiring activating all the small 24VAC coils on relays. The other runs to the other side of the coils. I still can't believe that you will have an opposite polarity running through the unit chassis. I know I can't measure it because I have tried. Why would it go back when the path of least resistance is to earth and not through the resistance in the wire? AC is AC is AC. It doesn't matter if its in a house, an Air Conditioner or a signal carrying cable. I suppose coaxial cable, with a single conductor, alternates with the shield and with the shield connected to earth ground and there is no second wire. By the way, I don't need to be convinced that you are an EE with whatever experience. To me, this is research and I will find a definitive answer that satisfies my curosity. Call me hard headed. And I defer back to my final statement in the last post. Anyway, this post was about cables being directional and not a dialog in electrical theory. They may never let me post again! Anyway, I am convinced that cables being directional is BS and ALL the EE's I work with are in agreement with that. Bigtee (Threads | Answers | This Thread)
