It looks like California does run on reduced voltage. See the following URL, for instance:
<http://www.world.std.com/~techbook/seec2_2.htm> http://www.world.std.com/~techbook/seec2_2.htm It says: 2.2.2 North America ANSI C84.1 "Electric Power Systems and Equipment - Voltage Ratings (60 Hz) sets the preferred nominal voltage at 120V and allows a range of 114 - 126V (240V nominal, range 228 - 252V). Equivalent Canadian spec is CAN3-C235. Voltage at a 120 volt nominal single phase receptacle should be 110 to 125V under normal conditions. However, the California Public Utilities Commission has specified that the service voltage shall be kept in the range 114-120V, with some exceptions. This was done because some studies showed a reduction in energy consumption at the lower voltages.

Daren, you bring up an interesting point. California's energy woes could possibly be band-aid if the voltage was reduced 10%. (maybe that is too big of a management issue, does anyone know?) Assuming that a large percentage of the users don't have switcher regulators then that would equate to a 5-9% reduction in energy consumption hence reducing California's power problems significantly till more power plants are built. That might lower the spot market price! --- "Nerad, Daren HS-SNS" <daren.ne...@hs.utc.com> wrote: > > It all boils down to $$$s! > Notice you don't see 110 V on the lines, probably not even 115 or 117 but as > close to 120V as they can keep it (except for you folks in CA, then this is > a digital thing, HA!). > > WHY? > > You consume more Watts if the V is greater! > > Check your wall outlet, what does it read? > > IT would be interesting to use this forum to do a quick & dirty survey. > Granted we can only hit where engineers feel like making measurements, & > when they do, but it would be interesting... > > Daren A.
