A 240volt cable goes from the other fuse to power the step down inverter. The power outlet cable from the from the inverter is 110volt and is wired into the Power Distribution box. This cable will have to be replaced and a 240v Power distribution box fitted. This leave the cables from the new distribution box to the Fridge and Microwave to be replaced.
I will have keep the 110v cable for the connection to the Inverter to A/c, with a inline fuse/breaker fitted.
The question is can the 110v cables to both the Microwave and Fridge from the power dist box be used or must they be replaced?
Someone else offered the cable used almost always is rated to 600 volt. That's plenty of rating especially since the current at 2X the orig voltage will be 1/2 of the orig installation. That's a good thing. I noted the JB's because some had big problems with sloppy connections (hidden cables melting, honest). I checked my own boxes and found were good. Whatever you do check some of your cables and confirm the rating, more important check with you local Elec. codes and make sure you're planning is in compliance. If something does go wrong you'll have insurance! Have fun!
