No, it is not recommended to use a 200A disconnect to feed a 100A main panel. The disconnect should always be rated equal to or higher than the main panel it is feeding to ensure proper protection and capacity handling. It is important to match the amperage ratings to avoid potential overload and safety hazards.

What do they replace when upgrading from 60 amp to 100amp?

Usually you just have to replace the electric panel and maybe the electric meter and entrance cable. It would be unusual, but the power company may want to replace the cable from the local transformer to your house.


Is it legal to buy a house with a 60 amp service?

Wow, never heard of it. Usually 100amp, usually it does not matter what the house has, because it is grandfathered in. But if you ever want to add anything to the service, you might be forced by codes to install a new 100 or 150 amp service, or you might not be allowed to do anything. Call the local power company and ask them if they will upgrade the service to the house for free. Some will. You will need an electrician to put in a new service panel. Could cost a thousand bucks or more depending on the current wiring. A home inspection would also be recommended before buying such an older house.
