sounds like you have a 100 amp service to your home.. that will need to be upgraded to a 200 amp service.. you shouldn't have any problems after upgrade..
Look on the handle end of the main breaker. There should be a number there. That is the amperage of the main breaker. That is the size of your house service.
A 350 amp service is not a standard service distribution. It jumps from a 200 to a 400 amp rated distribution equipment. The only way to obtain a 350 size service is to install 400 amp equipment and fuse it at 350 amps. The standard size home distributions in North America today are rated at 200 amps. The cost of the service differs through out the continent. Ask your local electrical contractor for an estimate on an electrical upgrade to the required service that you want.
Depends on the size of the service. 100 amp service will require 3 gauge, 150 amp service will require 1/0 gauge, and 200 amp service will require 3/0 gauge.
You will need two 8 foot ground rods. One placed under the meter base and another one placed 6 feet to the side next to the foundation. If this is a home I highly recommend you install a 200 amp service instead of a 100 amp service. Not much more expensive and you will have plenty of room for growth.

Yes you could use a 20 kva transformer in a home. Stymied as to why it would be done though. You would need at least a 100 amp service to the home to energize the transformer. Primary side of the transformer would draw 83 amps at 240 volts. If the question was to supply the home, again yes. It would be 100 amp service equipment that the transformer would feed into.
The average home built today has a 200 Amp service.
Too small.
No. A 120 volt 15 amp service will handle a maximum of 1,800 watts. Even a 20 amp service will only handle 2400 watts and that is at max load which you should never load on a 20 amp circuit. You will need a 30 amp 120 volt or 240 volt service for 2400 watts.
