Art: I think you know what I mean. I said 220vac, but 240vac was what I meant. I just followed the "Voltage" quoted in the subject line of the thread, which I did not start. And many layman call 110 for short I guess. Picking on close numbers just stirs controversy. But to keep it "Exact" we will say 240. But even you should have got the jest. I did not know the fellow was from the West Indies since I started seeing this thread after the subject line was changed twice. I do have a question for you: Are you the "Great One" that must decide when a thread ends. We are all here to learn and help each other and I have tried to help many over the years on this and other forums. I have the Thank Yous in my inbox to prove it. I resent the few on here that feel the need to disrupt that with striking out against another. Whom decides what is interesting to a huge membership as this, just you? Please.

The nominal United States Standard distribution voltage for single phase power is 120/240 Vac (120 Line to Neutral, 240 Line to Line). Look at the rating on your breaker panel, or check your copy of the National Electrical Code to confirm this. If you measure the voltage with your volt meter, you will likely see something either less than or greater than 120, the code also specifies an allowable range that the utility must stay within. Many other countries use 200 volt range supplies, here is a site that lists many of them, and gives the types of connectors commonly in use. http://kropla.com/electric2.htm If you look back at the original question, the person having the problem lives in the West Indies. West Indies doesn't appear in the web site referenced, but given the popularity of 220 Vac around the world, that's probably what he's got.=20 As far as equipment, many devices are able to handle multiple voltages. Older equipment, stereos etc, had jumpers to reconfigure the supply connection to the primary of the power transformer. Newer stuff with switching supplies can vary their pulse widths to accommodate the higher input voltages. The limit would be the ratings of input diodes, caps, etc. but if the manufacture rated his stuff for 100-240, he'd have the world licked. And sure enough, just for laughs, I've just looked at the five monitors in my office (1 sceptre, 2 HP's, 1 Panasonic, and 1 NEC) and every one of them has an input rating of 100-240 Vac, 50/60 Hz, making them saleable throughout the world. I hope this will solve the mystery once and for all.

I wired a special 220v outlet to my building outside. But in the tens of thousands of TV's that I have fixed, I have never had any customer that lived in the states say he used 220v on his TV. I don't know or care what they use overseas. I still can not figure out why anybody in the states would use 220v on a TV, and how they would even plug it in. I know the manual says this chassis will work on 220v, but why in the states? I am still confused about the member that says the CTC187 works fine on 110v but hums on 220v. I have not seen it answered does he live in the states or overseas? Does he have two power cords or are they running 220v to a standard 110 outlet. I do not think I saw this addressed, or I missed many post.

REALITY: 2 wires provide power, the only difference is the transformer setup that drops down the power to your home. In the land of 110 our transformer outputs 220V with a center tap that delivers 2 - 110V supplies or 1 - 220V supply. (Hey, isn't that sweet....3 supplies in one, eh?). As for the european 220V supply system......I can only guess, but you do not have that Center-tap. And I really doubt that the electric company is going to use 2 wires for power, then strap on a 3rd wire for grounding purposes (what purpose would that serve, except to reference the metal toaster casing to your bathtub water??). I'm sure the 220V tranformers have no practical need for earth ground, since all the electronics would behave as though they had an "Isolation transformer" on them. (That's the stepdown transformer...outside your home). Personally, I've heard that 110V is more dangerous than 220V......but I don't see that as a logical argument...What.....110 has less voltage, therefore we enjoy holding onto it longer, thus toasting us, but not the europeans???? If anybody has an answer to why 220 is safer than 110.... I'm listening. And that TRI-PHASE residential power supply??? Man, that is a load of hooey....of course, the government planners weren't reaching into their pockets, so I can assume they tapped into your dad's or grandad's wallet??

I am sure there could be other methods using odd switching type devices but extremes of design like that would be nonsense as it would be cheaper to get the correct model.

North America works on 110V and you are stuck with that, tough its not as safe and losses are greater. Now you have a situation where you wish more voltage, you have to cheat The mains supply is 3 phase, it is usual to run a line down a street and try to balance the power by having house 1 on phase 1 house 2 on phase 2 etc. To get 220V you have to cheat, you use 2 phases so a plug has 2 live's. But why in the name of Freddy would we have to do that. Options on the back of TVs have gone, that requires you have a mains transformer, costs money is a no no. American TV is only viewable in America and a few other countries, the rest of us use the PAL system a much later and superior system, it follows then there is no requirement for your sets to work here or X.
