Question Upgrading Electrical Service

I recently bought an older home and want to have the electrical service upgraded. It currently uses the glass screw-in fuses. The house has 4 bedrooms, 2 baths, living room, kitchen, dining area and large family room. I am concerned about what size service should be installed, since we currently blow a lot of fuses and I plan on adding electrical hot water heater(s), central air, maybe whirlpool tub, and a significant amount more lighting. I also plan on rewiring the current circuits with a larger gauge (probably 12AWG).
Would 300 amp service be over doing it?
Also, how would you suggest wiring a kitchen? Would two 20 amp circuits be good for the receptacles?

Please tell us the square footage of your house, so we can see if you are Bill Gates or not. However, 200 amps will probably be plenty for you. 300 amps probably is overkill unless you also plan to take up welding and open a pottery business with a kiln.

Kitchens are very regulated rooms with lots of codes. Search this forum for "kitchen" and read the posts. It'll tell you a lot of what you need to know. But yes, you need at least two 20-amp circuits for the counters. You might want more than two, and there are a lot of restrictions about what you cannot put on these circuits (e.g., lighting, fixed appliances).

Don't start this project without reading up on the codes. There are choices in some areas, but there are other areas where you have no choices. Ask more questions and we can help clarify things.

Try the following three links. Read and perform the format for calculating you demand load calculation telling you what minimum service size is required for you home then come back in with you questions that you still have.




The last two links when you get to them look to the left column and click on "show entire article"

Hope this helps
