Can you add a 20 amp breaker to main breaker if total breaker amp is 320 amp Main breaker max is four 150 amp breaker?
Total amps or calculated load has nothing to do with the number of breakers and their sizes. It is more complicated than adding the sum of the breakers, if you do that you will see that they would exceed 200 amps.It is based on square footage for the general receptacle and lighting loads,3000 watts is allowed for small appliances and this is just the beginning.Some experienced electricians have trouble with the calculations.If you are trying to see if you have enough capacity for an addition or some upgraded equipment,and you have breaker space,the chances are you will be O.K. Overloading the service would cause the main to trip.

Can you install a 2 20 breaker into a breaker box that has space but all other breakers add up to more amps than the 200 amp main breaker?
No, you cannot install a 2x20 amp breaker if the total amperage of all the breakers exceeds the main breaker rating, as this would overload the system. The total amperage of the breakers should not exceed the main breaker rating to ensure safe operation of the electrical system.

The 200 amp is usally the total amperage of all the breakers comming out of the box. You will probably never come anywhere near using 200 amps at one time.
