How do you determine if you have 100 or 200 amp service?

Look at the value of the breaker or fuses that control your main electric panel. look at the wire size coming in to the main lugs on service panel, I am assuming you don't have a main breaker or you would look at the breaker rating to determine service size. 2/0 copper or 4/0 aluminum service size 200 amps, #4 copper or # 2 aluminum 100 amp.

What size wire is needed for 100 amp sub panel that is 250 feet away from main panel?

A 1/0 MCM copper conductor will limit the voltage drop to 3% or less when supplying 100 amps for 250 feet on a 240/120 volt system. This calculation is for a full 100 amps at the panel. If exact amperage is known the conductor size can be reduced to match the known amperage.

Can you put a 100 amp breaker into a 200 amp panel?

Yes, if you have the correct size #2 wire going to it.
