Narrative:
Cruising at FL330 en route from phx to ewr, #1 xfer bus circuit breaker popped. Waited several mins and reset the circuit breaker. After a few mins the circuit breaker popped again along with the #1 engine aft fuel boost pump. We had numerous instrument and system flags. While we were trying to assess the situation the altitude warning horn sounded. We were able to control the cabin, requested descent from ATC, and landed uneventfully in ind.
