SAN JOSE (CBS SF) — Residents in a San Jose neighborhood woke-up in the dark Thursday after a PG&E power vault erupted into flames, officials said.

Crews initially responded at about 6:30 a.m. to the 2000 block of Brushglen Way on a report of a fence on fire and three trees burning, Fire Capt. Mitch Matlow said.

Arriving firefighters found the vault fully engulfed in flames and more than 3,000 local residents without power. Fortunately, the vault was isolated from homes in the neighborhood and no structures were threatened.

Firefighters had to wait to extinguish the fire until a PG&E crew could come out to turn off power to the vault. The blaze was put out about 45 minutes later, according to Matlow.
