ISB Sola regulators
Some info and a question. First of all I have created a chart with the specs for the ISB Sola 4000 & 8000 compared to the Hughes 30 and 50 amp autoformers. Here it is https://www.mexicocaravans.com/IS...

The 30A male to 50A female connector does connect both 50A hots together and that's OK since the maximum amps is 30A.
A 120V 66A connection means that the neutral can carry 66A and the RV wiring is only rated for 50A. ie For a 120/240V 50A circuit the neutral wire maximum amps is the difference of the 2 hot wires and hence a maximum of 50A. This is why all 3 wires are the same size and rated for 50A.
I suggest you remove the 8000 unit from the chart and/or make it very clear that this unit is not compatible with a 50A RV.
Are you sure? It seems to me if you butchered a 50 amp extension and bridged the black and red wires using a murette and a suffiently low guage wire to the unit, in and out, it should handle 50 amps OK. If it it can handle 60 amps as it says in the documentation, the factor should be the guage of the wire. I am assuming the 2 hots of the 50 amp cord are the same phase and only diference between the 50 and 30 amp is the total sum of guages of the wires.
It woudl be nice to see inside an 8000 and see what the diference with a 4000. Terminal size, etc?
