I realize that but they will still work. Hardly a brownout.

Strange, when I google brownouts in CA I can't find any mention of old wiring being the problem.

83 volts RMS, the cheap meters will see about 103 volts.

The electric company is responsibly for the upgrade, even have collected money to do it, but have done stock buybacks instead, about 20%. Money in escrow was borrowed to fund the buy backs is the rumor.

What kind of meter you talking about? What is a cheap meter. RMS value of a alternating sinusoidal waveform would be the same voltage as a direct current voltage to do the same resistive heating.

Google again Berton. Over stressed electric grids are a cause of brown outs just as a generator station inadequate output is.

Read again Thumper, I didn't say electric grids could not cause a brownout, I said I could not find a article saying the grid was the problem in CA. If you can find one I would appreciate it.

Thumper,
Most meters read a peak voltage AC, 108 volts RMS generally reads about 120 volts on meters not specified as being RMS. There are times RMS is much better, but most times the peak is just fine.

The lines are old as in designed earlier for a lower demand period of time, not as in being worn-out. Copper does not wear-out when carrying power. Feeding two hundred and sixteen houses from a grid feed designed for ninety houses pushes the limits.

Last night I checked with a brother in law who has worked in electricity all his life and a nephew who has done the same work. Both are very knowledgeable and both support what Corky has posted. BTW, both live in Oklahoma.

For the first time since January, rolling blackouts were ordered in California today, turning out the lights in approximately 500,000 homes, including some in Beverly Hills.

Officials at California's Independent System Operator (ISO), which monitors the state's power grid, called a Stage Three alert at midday because of increased temperatures, a higher power demand and a lack of electricity from the Northwest.

Further complicating the situation was the closure of two power plants. One was offline for maintenance and the other was shutdown due to unpaid bills, the officials said.

Yesterday, the ISO ordered Pacific Gas and Electric and Southern California Edison, two of the state's biggest utility companies, to cut a total of 500 megawatts of electricity, enough power for roughly 500,000 homes.

ISO spokeswoman Stephanie McCorkle said the outages were split between Northern and Southern California. A spokesman for Southern California Edison said the blackouts affected the Los Angeles-area cities of Chino, Beverly Hills, Long Beach, Visalia, Banning, Kern and Santa Monica.

Cork, I think you are mistaken. Most meters read RMS Vac. House voltage is generally about 120 Vac rms. For peak, multiply by 1.414 the inverse of .707. Peak to peak house voltage is around 170 V.

Thumper,
Sorry, I blew it, I used peak when I meant average.
Most volt meters read some form of average voltage, depending on the actual waveform, unless specified as being RMS values.

RMS times 1.1 is usually considered typical for most conversions.
