Hi Doug,
I've seen the reverse polarity fuses blow when I attempted to do double conversion using my Magnum inverter/charger. The inrush current is too great. Why did I attempt that? Because the Magnum dislikes MOST gfci outlets. I did add a switch before my converter so when on limited power I can use the dedicated inverter powered outlet in the kitchen.
BTW after the fuses were replaced the converter was just fine.

Are you sure it is fried? Did you check the reverse polarity fuses on the output of the converter?
The reverse polarity fuses. WHEN I have seen them blown from REVERSING the Coach battery connections, usually they did not protect the Converter and the converter is defective. Now, the OP stated he had a 50 amp wired to a 30 amp. WHY THAT FRIED ANYTHING IS A MYSTERY. But, I assume he meant a 220 hit, not 50 wired to a 30 which would not cause any problem. IF a Converter takes a 220 hit, the Polarity fuses will NOT save the Converter. They only save if you do indeed miswire the 12 volt battery. Doug
