SOUTH ORANGE, NJ - Power was restored Wednesday to a building in the center of South Orange that houses the municipal offices after it went out on Tuesday afternoon, leaving the building without power for almost a day.

Municipal offices in South Orange shut down early on Tuesday after an electrical fire caused power to go out in the building where the offices are located. Other businesses located in the same building at 76 South Orange Ave. were also impacted by the power outage.

The electrical fire started at 1:20 p.m. in an electrical vault underground at the building. The vault houses electrical supply and transformer equipment.

Firefighters put out the blaze around 3:20 p.m. on Tuesday. After the fire was put out, PSE&G worked to repair the electrical vault until it was back up and running around 10 a.m. Wednesday.

South Orange Fire Chief Dan Sullivan said the cause of the fire is undetermined but "likely due to age and high energy demand due to the extended hot weather and the demands that impact electrical equipment."
