Just when I thought all power was created equal! Ok, THAT explains a lot. I did not realize that a lot of the overseas power was made this way. That explains that when I was recently in the Philippines, I saw a power(secondary power) swinging close to the ground. As I looked at, I only saw ONE conductor that was insulated. I was worried that the other conductor, was also hot, and uninsulated! Now, it makes sense that it was not insulated. Again, thanks. I like to learn about these things and have had an interest in BASIC power, both AC and DC since I was young.
