LOS ANGELES (Reuters) - A utility worker overloaded an electrical circuit and caused a massive power blackout across much of Los Angeles on Monday, snarling traffic, stranding office workers in elevators and sending fire trucks with blaring sirens racing around the city
Some two million people were hit by the outage, which plunged busy intersections into chaos, jammed cars on the freeways and sent office workers streaming out of downtown buildings to mill about on sidewalks. Those trapped in elevators made frantic calls for help.
The utility worker "directed too much amperage into a circuit that did not have the capacity to handle it," said Kim Hughes, a spokeswoman for the Los Angeles Department of Water and Power.
The resulting power surge triggered a safety mechanism that shut the system down, Hughes said, knocking out power for more half the city's four million people as well as some surrounding communities and north into the San Fernando Valley.
Power was largely restored within 90 minutes, but the outage jangled nerves in Los Angeles one day after a masked man thought to be an al Qaeda associate threatened America's second-largest city in a videotape released on the anniversary of the September 11 attacks.
"The fact that this happened the day after September 11 (caused) a heightened sense of concern," said Los Angeles Mayor Antonio Villaraigosa. "I am here to assure you that our city is prepared to handle these situations. In fact power was restored to the vast majority of DWP customers, 90 percent, within the first two hours."
