We installed a mobile setup very similar to an RV setup except customer has both 120 and 208/240 (will work on either) loads. We have tried all of the L2 options. There is an external selector for shore/genset and the MP units are fine with the genset but does not recognize and switch over when 208 is applied. Genset is a 12K Onan QD and the shore is 120/208V 50A. Anyone with success on this type of setup?
