you can replace the breaker it takes 2 seconds literally it pluggs in just like ur recepticals, and the wiring don't make a shit is either 110 or 220 VOLTAGE amperage makes no diff.....and....you can go to 100amp breaker if you want and it will still only draw what the appliances are asking for no more no less..... easy way to tell is plugg everything in....if the breaker trips ,reseet it and get a larger one, it is VERY SIMPLE
