The input cord will have to be change to a standard 30 amp and the output will also need a 30 amp adapter.
And my previous question about the size of the power cord still applies. If this is to be for up to 30amp then the cord needs to be at least 10 gauge wire - and a 30amp plug and whatever else would be needed - if you are going to plug your whole RV into it you need the right outlet - and all the wire has to be of large enough gauge. I think maybe some modifications could be required. I know the ISB device does not come wired as I did my own wiring to fit my needs. There may not be a simple solution.
