Narrative:
Cruising a 410 the right pack tripped. I was running the QRH procedure when the left pack tripped off. Both pilots donned oxygen and established communications. I requested and was granted a descent from ATC. Now running the dual pack failure in the QRH; I was able to reset the packs using the trip reset button. At this point the cabin was controllable. The cabin never climbed above 10;000 ft and the event was near top of descent so we intercepted a normal descent profile to our destination.
