I've not opened a 50 amp version but there would either be a similar dual trim pot or perhaps two separate pots, one for each leg. However, I wouldn't fool with this unless using a calibrated meter, otherwise you'd just be guessing. ;)
Thanks for the picture and advise. Mine in buried behind stairs, panels and the converter so there's no way I'm going in without a calibrated VM and well understood instructions. To my calibrated ear, the hum is no different today than it was a couple years ago when I installed it. Installed a 30A EMS on our previous trailer and never knew it was there - unless it detected something it didn't like of course.
