Short circuit results in arc flash at Oklahoma nonprofit institute
A Noble Foundation building suffered an electrical malfunction in May that caused the evacuation of employees in Ardmore, Oklahoma when the basement filled with smoke.
Adam Calaway, foundation director of communications, said the foundation’s facilities group had “worked through much of the night and determined the probable cause of the electrical malfunction to be a short circuit on at least one, and possibly two, of the main electrical feeders to the building.”
