A defective underground electric cable was to blame for the extended Jan. 2 power outage in Westchester, LADWP spokeswoman Kim Hughes said.

The outage began at 6:39 a.m. and knocked out traffic signals at Lincoln Boulevard and Manchester Avenue as well as other nearby intersections along Lincoln, including Loyola Boulevard, 83rd Street and LMU Drive. Morning commuters dodged each other at the busy Lincoln and Manchester crossing before traffic officers arrived at about 10 a.m.

Many businesses near the intersection lost power for as long as eight hours, with workers fully restoring service at 8:55 p.m., Hughes said.

The damaged cable was located in the 7400 block of Manchester.

“We had to replace the entire cable. It was a complicated situation because the cable was very large,” Hughes said. “Often what makes an underground repair lengthy is when there is a car or vehicle parked on the vault above the cables. There was some traffic that needed to be dealt with, so it took some time for us to be able to get to the vault.”
