Hi. guys the main fuse coming into my house is 60amp .I am having an extention built and also want electrics in the garage. adding up the amps and taking in diversety ( Read up a bit) 60amps will not be enough. will the electric company be able to just replace the fuse with a 100amp, or will they have to run a new cable to my house.. the house is about 25 years old. Also if its just a matter of changing the fuse will my elecrtician have the autheroty to change it because there is a seel on the fuse. I do not want to get in trouble if he does not follow the rules. thanks
