Why is electricity in the US usually delivered to residential customers at 110 volts instead of 220 as in Europe and some other countries? Is it a safety issue or economic issue?
As a NGG stockholder, I really don't know. Any help?
I don't think there is a logical reason for the difference. A more significant difference is that the UK (and the rest of the world outside of North America) also has a 50 cycle system, whereas we have a 60 cycle system.
Thanks for your replies. Let me tell you what brought this up. A friend of mine here in the states sent his mother in law in France an iron (for ironing clothes) as a gift. She got an adapter plug and started ironing, She reported back later that it really worked well except for one thing. It went up in smoke after about 10 minutes!
I'm aware that our low voltage plugs & lights take half of the 220 coming in. Except for safer lighter jolts when you touch the terminals, still not sure why we split down to 110 for the small stuff.
Actually U.S. residential power is 220v, with a center tap (neutral or ground). You get 110 volts between each feed and the neutral, or 220 volts (e.g., for your air conditioner or electric stove) between the feeds. I'm not sure how the Brits are wired.
