Can you switch out your 100 amp breaker to a 200 amp one for a service upgrade if your supply wires are already 2-0 copper that is can I keep my existing panel since I have all the space I need?

I doubt if you can fit a 200 amp breaker into a 100 amp panel and it is illegal as the bus bars in a 100 amp panel are rated at 100 not 200 amps. The panel must be of the same capacity in amps as the main breaker that is installed in it. You can go smaller but not larger. The other problem is that a 200 amp service required three ought (000) wire. 000 copper wire with an insulation factor 90 degrees C is rated at 210 amps. Two ought (00) copper wire with an insulation factor of 60C is rated at 145 amps, 75C is rated at 175 amps and 90C is rated at 185 amps. Buy a complete house package that has the main breaker and all of the appliance breakers plus a few breakers for 15 amp circuits, all for one price that is cheaper that buying individual pieces.

Can you upgrade a 100A main circuit breaker to a higher amp?
I doubt if the 125 amp breaker will fit into a 100 amp box. This is due to the rating of the box only being rated at 100 amps. If this exchange could be made then the service conductors feeding the box must be upgraded to take the 125 amperage that the breaker will allow on the conductor.
Can you replace a 100 amp panel with a 200 amp panel using the same wires coming from meter?
No the service wires need to be upgrade to 3/0 copper or 250 mcm aluminum. This will require a power company to disconnect so you can upgrade the service. These wires are always hot unless the power company disconnects from their source. Do it right pull a permit and upgradeAdditional information:Some meter base boxes include a shutoff/breaker. If you are only looking for additional space inside the breaker panel, and do not upgrade to a higher amperage breaker inside the meter base, you actually CAN use the same wire, provided that it is long enough to reach into the new breaker panel. The breaker of the meter base protects from the over-current condition.If you have the shutoff in the meter base, you will obviously be able to disconnect service while you perform the necessary changes. While you are working on the service, lock-out the meter base access to prevent anyone from turning the power back on.It is still recommended that you pull a permit and work with a qualified electrician.
Do you need to rewire your house to upgrade your panel to 200 amps?
No, you can just install a 200 amp service with your existing wiring. But, you need to make sure the wiring is safe and not deteriorated to the point it has become dangerous.
Can you add a 20 amp breaker if therE is room?
You should add only with a proper load calculation. You should probably have a licensed electrician look at the situation first. You can find a licensed electrical contractor at www.contraxtor.com to help with your electrical service upgrade
What would cause the main 100 Amp breaker to to break Mine did last night in the home Its a 100 Amp panel?
If you will notice, your individual breakers add up to much more than 100amps. So it is entirely possible not to trip an individual breaker but still draw more than 100amps, which would cause the main to trip. If you haven't had this problem in the past, I wouldn't worry about it unless it happens again. If it does, you need to upgrade your service to more amps. It is entirely possible your main breaker has malfunctioned but that is not easy to test. If it is replaceable, and if you have further problems, you can consider replacing the main breaker to see if that fixes the problem. That is much less expensive than upgrading the service.
When do you know if you need an electrical service upgrade?
1) If you are tripping the main breaker and you do not have an electrical fault in the home. 2) If you are installing additional circuits or appliances and you expect to exceed 80% of the load capacity of the existing service panel.
Do you need to upgrade the 100A service in your house to run power to a detached garage?
All depends on what type of equipment you are going to operate in the garage. I would suggest you call an electrician. You can connect to your existing 100 amp circuit if there is an empty spot for a breaker.

How do you upgrade the service from a 120V 100A circuit breaker to 240V 30A for appliances like ovens and dryers?
Have an electrician wire you a proper line for the appliance. You were just kidding about the 100A, right? 10, or 20amp, not 100.
