Powering the flight-line
Airman 1st Class Ethen Price, 773d Civil Engineer Squadron electrical systems journeyman, checks the voltage output from an enclosed high-voltage cable system on Joint Base Elmendorf-Richardson, Alaska, Sept. 22, 2014. To provide a safer work environment, the exposed 4,160 high voltage wiring has been replaced with an enclosed regulator system where the electricians can safely walk inside the vault.
