300 Edison customers without power after vault explodes in La Puente
An underground electrical vault exploded Tuesday afternoon in La Puente, forcing the temporary evacuation of 30 homes and knocking out power to 3,200 Southern California Edison customers, 300 of whom were still without service at 4 p.m.
The series of explosions occurred about 1:35 p.m. at North Del Valle Avenue and East Amar Road, said Edison spokesman Steve Conroy.
There were no reports of injuries, but county firefighters ordered a brief evacuation of 30 homes as a precaution after the blasts.
About 3,200 customers were immediately without power, but after redirecting lines, Conroy said that number was reduced to 300. He said some customers might remain without power into the early evening or even overnight as crews continue to try and redirect additional lines.
Edison officials are still looking into the cause of the blast, but Conroy said crews found water inside the vault.
