The 2 30 amp breakers trip when powered up??????? If so, one or both of the wires from the circuit breakers to the fuse panel are shorted. Another test would be to disconnect the 2 wires at the breakers and the fuse panel and ohm both wires to ground. They are bolted to a brass stud on the top of the fuse panel.
