In a Jan. 27 letter to the regulators, Southern California Edison revealed new details regarding its electrical equipment before the Eaton Fire.

Southern California Edison has reported a Jan. 7 fault on a power line that was connected miles away from the lines located near the origin of the deadly Eaton Fire that sparked that day.

Edison International Inc.‘s Southern California utility equipment created a powerful electric arc above Altadena, Calif., that ignited the deadly Eaton fire, a law firm suing the utility says, citing new video footage from a nearby gas station.

Edison says current increase "remained within the design limits and operating criteria" for the circuits and "did not trigger system protection on these lines."

The utility company maintained that the current increase remained within the design limits and did not trigger system protection on these lines.

High-voltage power lines saw a temporary surge in electrical current in the area where the deadly Eaton Fire is believed to have started, Southern California Edison said.

Attorneys who claim malfunctioning Southern California Edison equipment caused the deadly, destructive Eaton Fire on Monday released video they believe shows sparks from Edison power lines igniting the blaze.
