My 2009 isolation transformer model 3600 has 2 red buttons on the front. The right hand button trips with sudden increase in loads that the Quattro doesn't handle. These loads seem to be the inductive ones which come from my induction hob or maybe from electric motors in freezer or washing machine. I have to keep the shore line amps down to 10 on the regulator. I want to eliminate these MCBs by bridging them out. The later transformers don't have them. Installation is in a steel Dutch barge.
