[QUOTE="johnb2713, post: 547072, member: 35153"] Well Mr Aargh you maybe should do a little more research rather than relying on gut feeling. The fuse characteristics in service head you will see that an 80amp fuse with a 100 A current will take 2.7 hrs to blow, 180 amps it will blow in 2 minutes, with 84 amps it wont blow. You also need to consider how likely it is for someone to be using 8kW shower whilst the car is on charge, the washing machine just happens to be taking maximum load at that time and somebody else is boiling the kettle. even if were to go on for several hours in this state, the fuse still wouldn't blow hence my advice the OP had little to worry about but request the upgrade anyway.
