Five multiconductor Type TC cables rated for 75°C, each constructed with three 800 kcmil copper conductors, are installed in a single layer in a ventilated uncovered ladder cable tray with a maintained spacing of not less than one cable diameter between cables. All three conductors within each cable are considered current-carrying conductors. What is the ampacity of each 75°C 800 kcmil copper conductor? (Round the FINAL answer to the nearest whole number.)
