I am not telling SilerSurfer to use only one phase, I have consistently told him it is a bad idea even in the short term. I do say that using one phase will only result in a flat battery long-term and not a burn out stator.
The 30 A fuse is there specifically to protect against a short circuit fault in the rect/reg. Short circuit faults in any of the sub-circuits will cause the fuses for those specific sub-circuits to blow before the main fuse blows. I do not like the way in which Honda has integrated the main fuse into the wiring loom and that issue I have covered in my post "Charging System Wiring Improvement". The main fuse is not a protection device to limit the output of the generator, that is the function of the rect/reg. There is unfortunately no protection against a failed rect/reg overcharging the battery or damaging the electrical system. It would be simple to add such a device, called an overvoltage crowbar.
I said one phase will only provide a limited amount of current, power if you prefer, and that it would be insufficient to run the full electrical system. The two phases not connected to the rect/reg will not contribute any power to the electrical system.
