I work for a water district in southern California. I recently paid an engineering firm to complete Arc Flash studies on 20 sites. If in 5 years there are no changes to the equipment. do I need to have a complete Arc Flash study done? Do I simply document that no changes are made? Can this be done by any qualified person?
