Updating a house to 100 amps
Dividing a large electrical project into smaller pieces won't save you any money, but it will make it easier to budget.
Some projects should be always be grouped together.
Because the budget to upgrade 100A panel to a 200A will be from ,500.00 and high. To replace a 100 Amp breaker panel with a 200 Amp, questions need to be answered and measurements made.
To replace that wire between your Meter and Transformer will cost a lot of money.
For example, if you are upgrading an old fuse box to a circuit breaker, that's a good time to upgrade the service to your house to a 200 amp service, simply because the service will often have to be disconnected and reconnected anyway. Once this is done and the wiring already in place is up to code, you may be able to break the rest of the projects into two or three sections, like the kitchen, second floor or garage.
Running a single electrical line through the house can cost between 0 to 0 per line, depending on the length of the line and the construction of the house.
A good rule of thumb is to get quotes from three electricians.The cost depends more on the age and construction of the house, rather than the size of the home.
