Judging by your question I'm going to take a guess and say you should probably not attempt to do this yourself. Nor do I recommend it.
That being said.
You can either have your service upgraded to 200amp, and install a 100amp double pole breaker and branch it off into a 100 amp sub panel. You could most likely re-use your old panel for the 100 amp sub panel.
Or...
You could have your new 200 amp panel installed in a different location and your current panel wired into it for 100 amps.
What else can I help you with?
What is the minimum service size for a 225amp residential service?
A 200 amp service panel with a 60 amp sub-panel.
What size breaker do you use for a 100 amp sub panel?
A 100-A sub-panel would be fed from a 100-A breaker.
Is a 50 amp sub panel enough to do a bathroom and kitchen?
Possibly if the kitchen does not have an electric over and electric cook-top and no eclectic water heater in the bathroom. If they are electric have an electrician evaluate what is being powered in the kitchen and the bathroom to determine if a 50 amp sub-panel is large enough. I would for sure at least go with a 60 amp sub-panel.

Can you put a 60amp breaker and a 50amp breaker on a 60amp subpanel just as long as they are not being used at the same time?
You can. Using these size breakers in a 60 amp sub panel might be pushing the limit for breaking the sub panels feeder breaker. The breaker feeding the sub panel will have to be no bigger than 60 amps because of the main bus bar capacity of the sub panel. It would be better to install a 100 amp sub panel and then there would be a bit of a buffer and you will have the ability to add additional small load circuits.
Can you feed a 60 amp sub panel from another 60 amp sub panel?
Yes, you can feed a 60 amp sub panel from another 60 amp sub panel as long as the total connected load does not exceed 60 amps. Make sure to properly size the wire and protect the circuits with appropriate breakers to ensure safe operation of the sub panel.
What would happen if a 200 amp breaker is used in a 100 amp sub panel?
There are two things to think about here. First of all a 200 amp breaker will not physically fit into a 100 amp panel. This is so designed because the panel buss is not designed to conduct 200 amps before the current is cut off. A 100 amp rating on the panel is the maximum amount of current that the manufacturer states, that can be handled safely. Second if the 200 amp breaker is in the main panel then everything downstream from that breaker has to be rated for 200 amp conductivity. The wire size will have to be 3/0 from the breaker to the first over current device in the sub panel which will be the sub panel's main breaker. The sub panel can not be a load center but will have to be a combination panel. I doubt that the 100 amp sub panel's main breaker lugs would be large enough to connect the 3/0 cable.
How to wire a 100 amp sub panel from a 200 amp main panel?
To wire a 100 amp sub panel from a 200 amp main panel, you will need to install a double-pole breaker in the main panel to supply power to the sub panel. Run appropriate gauge wires from the main panel to the sub panel, ensuring they are properly sized for the amperage. Connect the wires to the corresponding terminals in both panels, following all local electrical codes and regulations. It is recommended to consult a licensed electrician for proper installation.
How do you wire a garage sub panel box from a 100 amp breaker in the house main panel?
you propaly can't sub panel from 100 amp panel. Just not enough amperage to be worth while. i had to up grade t a 200 amp main first and then I was able to take a 60 sub panel from that.
What size wire is needed to feed a 125 amp sub panel from a 200 amp panel less than 200 wire feet away?
For a 125 amp sub panel located less than 200 feet away from a 200 amp panel, you would typically use a 2 AWG copper wire or 1/0 AWG aluminum wire to safely carry the current load. It's important to follow local electrical codes and regulations when selecting the wire size.
You want to install 200 amp service but the sub panel is on the other end of the house and you dont want to rewire the whole house all at once?
You can install a 200 amp sub panel near the existing sub panel at the other end of the house. This will allow you to upgrade to 200 amp service without rewiring the entire house at once. Be sure to consult with a licensed electrician to ensure the installation is done safely and up to code.
What are the components included in a 200 amp sub feed lug kit and how are they used in electrical installations?
A 200 amp sub feed lug kit typically includes lugs, mounting hardware, and a cover. Lugs are used to connect wires to the electrical panel, allowing for the distribution of power to various circuits. The mounting hardware secures the lugs in place within the panel, while the cover protects the components and ensures safety. These components are essential for safely and efficiently distributing power in electrical installations.
What is the minimum service size for a 225amp residential service?
A 200 amp service panel with a 60 amp sub-panel.
What size breaker do you use for a 100 amp sub panel?
A 100-A sub-panel would be fed from a 100-A breaker.
What is the maximum amperage capacity of a 40 amp sub panel?
The maximum amperage capacity of a 40 amp sub panel is 40 amps.
What is the largest sub panel you can install off from a 60 amp main panel fed by 100 amp service?
You can install a 100 amp sub panel off a 60 amp main panel fed by 100 amp service. This allows for the sub panel to be adequately powered with headroom for future circuits or expansions. It is important to ensure the wire size from the main panel to the sub panel is sufficient to handle the load.
Can you use a 40 amp breaker to feed a sub panel?
It is not recommended to use a 40 amp breaker to feed a sub panel, as the breaker size should be based on the size of the wire and the load of the sub panel. It is important to follow the manufacturer's guidelines and local electrical codes when determining the appropriate breaker size for a sub panel.
