Power has been restored to all of the buildings affected by a widespread power outage at the University of Hawaii-Manoa this afternoon.

The power outage struck during lunchtime, affecting 20 buildings including the campus center complex.

University facilities official David Hafner said electricity had been fully restored by 1:45 p.m.  

The outage prompted a shutdown of lines into areas that normally serve lunch, including the cafeteria, Starbucks and Jamba Juice, a University official said.

University spokesman Diane Chang said the outage occurred at 12:20 p.m. and was caused by contractor hitting an electrical line.

Hafner said people were trapped temporarily in three elevators in different buildings.

He said the contractor who tripped electrical circuits was working on building a new student recreation center.
