I have installed 18A 12|12 Orion (non smart) converter. assuming it is limiting current to 18Amps i have installed 25A breakers and 2.5mm2 wires. However it actually surges up to 50-60Amps and burns my breakers and heats my wires :( Why does it say 18A , when it is makes it up to 60 ?. if i add 50amps breakers , after some time current drops to 25-30 Amps, which still heats the wires .
