pg&e_blackout(2).jpg5:09 PM: PG&E officials said some San Francisco customers might experience brief power outages this evening as crews work to repair damaged equipment in an underground vault that sparked a fire this afternoon.

The fire was caused by a failed secondary fuse and not a cable failure as PG&E initially reported, utility spokesman Jason King said.

The cause of the equipment failure is under investigation and King said it was not known at what time repairs would be completed.

The fire occurred at about 2:45 p.m. in an underground vault in the area of Clay and Kearny streets, and firefighters and police officers responded to the scene.

Police had shut down streets in the area, but the streets have since reopened.

Kearny Street was closed between Clay and California streets; Clay Street was closed between Grant and Kearny streets; and the immediate area around Portsmouth Square was also closed.
