America</title></head><body>
<div>Hi</div>
<div>In the UK the voltage is usually 240 volts whereas in the rest of
Europe it is 220. However we are united by a standard voltage of
230 +/- 10% They like to keep the voltage up since it sells more
electricity. However if the local renewables push the voltage
too high it can still cause problems on low load days.</div>
<div><br></div>
<div>Wikipedia says:</div>
<div>"All of Europe and most of South America, Africa and Asia,
as well as Australia and New Zealand use a supply that is within 10%
of 230 V, whereas Japan, North America and some parts of northern
South America use a voltage between 100 and 127 V. In general, most of
the world uses the 230V standard. This also means that standard 230V
equipment can be used in most parts of the world, with only a minor
change in the equipment's electrical plug for a specific
country."</div>

<blockquote type="cite" cite>thank you for that! i've often wondered
myself where the 110/220 and other random voltages mentioned from time
to time came from (as opposed to 120/240 which is all i've worked with
in my electrical career). i've often assumed that the other
numbers were grandfathered in from other systems, but was never really
sure.</blockquote>

<blockquote type="cite" cite>If the change to 120/240 was in the 60's
then why do some appliances still reference 110-115V?</blockquote>

<blockquote type="cite" cite>i'm impressed, it must have been
something working your electrical career thru, among other things, the
change from DC utility systems to AC systems<br>
