Ok we bought a rv with a iota 55 m series converter. WE had a place set up next to our house to set rv we had a dump,water , and electric pedestal put up. We have 50 amp rv WIRE IN BLK, RED, WHT, GRN outlet 4 prong after checking and rechecking the voltage (246v) plugged in the rv within a min or two the smoke started to come out of the compartment where the converter was. the converter was burnt up WE pulled the power cord. MY question ,does the neutral and ground have to be separated in the panel feeding the outlet? and does anyone have a clue what we could have done wrong?
