Exterior electricians keep the power running
Brett Derouin, 773d Civil Engineer Squadron electrical systems journeyman, removes a transformer after cutting old powerline cables on Joint Base Elmendorf-Richardson, Alaska, Oct. 15, 2014. Electricians test high-voltage lines to ensure they are de-energized before any work is done on them. The removed cables are recycled for further use or reused as powerlines if salvageable.
