Casualty power can be rigged from where?

Casualty power can be rigged from where?

• A. ABT
• B. ABT2
• C. Engine room main switch
• D. Battery bank

Answer: (A)

Casualty power is the emergency electrical supply that keeps essential equipment running when normal power is lost, routed through a dedicated emergency distribution point. In this setup, the primary source for casualty power is ABT because it is the designated casualty power transfer point designed to feed emergency circuits like the AFFF system. The engine room main switch controls the ship’s main propulsion power and isn’t the path for casualty circuits. The battery bank provides DC energy for certain systems, not the AC casualty power distribution used for the AFFF transfer equipment. ABT2 would be a backup option if the primary ABT is unavailable, but the standard practice is to rig casualty power from the primary ABT.
