## Discrepancy

(CAN) DURING FLIGHT, CREW EXPERIENCED TRIPPING OF SEVERAL FUEL BOOST PUMP CIRCUIT BREAKERS.  CREW DIVERTED TO THE NEAREST SUITABLE AIRPORT WHERE MAINTENANCE REPLACED THE GFI RELAYS FOR THE BOOST PUMPS THAT HAD THEIR C/B`S TRIP,  ALL ELECTRICAL CONNECTOR`S TO THE RELAY PANEL WERE CHECKED FOR TENSIONS AND CLEANLINESS, AND GROUNDS TO THE PANEL INSPECTED WITH NO FAULTS.  THE GFI SYSTEM WAS TESTED WITH NO FAULTS FOUND.  FURTHER TESTING BY TRANSFERRING FUEL USING ENGINE GENERATORS, APU, AND EXT POWER, WERE CONDUCTED ALL WITH NO FAULTS FOUND.  THE AIRCRAFT WAS THEN RETURNED TO SERVICE.
