I have done a bit of electrical work installing lighting and outlets and running new service to new appliances. I need to upgrade an old electrical breaker box from 100 amp to 200 amp. I want to know where I can find the specifics of the procedure so I can determine if I can do it myself seeing as how electricians are too expensive for me. For example do electricians simply call the power company and have the power supply shut off to the house or do they use special tools and or skill in removing and hook up the utility hot wires to the new box? Can anyone recommend a good book on this and or say something more about the procedure?
