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...

This has come up again with a customer. RV 50 amp is really 2 30 amps split between 2 different zones on the RV, A 50-30 amp adapter does bridge the 2 halves of the 50, but ONLY FROM the point of the RV, not the pedestal. A 50-30 amp adapter It is designed to plug into a 50 amp pedestal where it only picks up 1/2 of the circuit it then bridges the 2 inputs from the point of view of the RV..If it bridged the 2 halves at the pedestal end which are out of phase, it would trip the breaker..
Therefore the only way to get true 50 amps at the RV is to use 2 ISB 4000's and an an 50 amp adapter cable splitting the 2 phases, one to each of them. A big headache unless you have room to wire 2 of them permanent into the rig.
In other words buy the 4000.
