Yes.
Additional InformationBreakers and fuses protect the wires to prevent fire. The 100 Amp breaker in the meter base (main) protects the wire from the meter base to the breaker panel. The 50 Amp breaker in the breaker panel protects the wire from the breaker panel to the outlet. Sometimes the 100 amp main breaker is located in the panel.
If you are asking "Can you use two 50 amp breakers for the main breakers with a 100 amp service, then yes you can. The National Electrical Code allows you to use up to 6 breakers as the main overcurrent protection.
Three or four would be normal. The total current should not exceed the rating of the main panel, so depending on how intensively the different circuits are used, more could be installed.
It depends on duty factor of each connected device. For a continuous load you can support 80% of 125 Amps which is 100 Amps. That would support two 50 A breakers each supporting a 40 Amp continuous load. If your loads were less and not continuous you can have more breakers. It is all a matter of supply and demand.
In a 200 amp service panel, you can technically install multiple 50 amp breakers as long as the total load does not exceed the panel's capacity. However, the number of breakers is also subject to local electrical codes and regulations. Generally, the total amperage of all breakers should not exceed 200 amps, considering the load calculations. Always consult a licensed electrician to ensure compliance with safety standards and regulations.
As many as you need. Just make sure the main breaker of the subpanel stays below 50 amps (the rating of the subpanel) and the input to the subpanel, whichever is lower.
I've never heard of a 50 amp b-e-a-k-e-r. You can put a 50 amp b-r- e-a-k-e-r in a 60 amp panel; but you can only have an additional 10 amp breaker along with it. You may need to consider adding another larger panel or a separate 50 amp breaker box.

Yes. Many installations have breaker totals higher that the main breaker of the panel. It is worked on a percentage basis. Not all of the breakers will be on at the same time. In a home, on a 100 amp panel the average load is 50 - 60 amps. The 100 amp main breaker is protecting the 100 amp rated panel board. If the load current goes higher that the panel board is rated at, the main breaker will trip to protect the board.

This would typically be seen in older residential installations where the service was of such a high amperage that the mains required larger breakers than were available (for that panel). Placing two breakers in parallel allowing sharing of the load. Two breakers per (split) phase would total four breakers. Two breakers of 50 amp rating each (in parallel) provide (generally) 100 amps of protection. Two sets of two would provide mains protection for a 200 amp service.

If the main breaker has ground fault detection, and the fault is a ground fault, then only the main may trip. Also if the fault is a direct short, the fault current may be several thousand amps, much greater than the trip point of both breakers. Breakers have an I^2T curve (current squared-time), which is an indication of how fast the breaker will trip at a given overload. When both breakers are overloaded, the breaker with the faster I^2T rating at that current level will trip first. This would be an indication that the breakers are improperly specified or adjusted.

Answer for UK, Europe and countries running a 50 Hz supply service.It is acceptable to connect two 15-amp breakers to a 30-amp supply. It woud also be acceptable in some applications to connect three 15-amp breakers if it were known that the total current would not exceed 30 amps. For example in many UK properties there is a 60-amp supply, and connected to this there are two 30-amp supplies for the ring-circuit and the cooker, plus also a 10-amp lighting supply.
In North America a two pole breaker usually represents a load that requires a 240 volt source. Larger current load appliances use 240 volts to reduce the feeder size and there by reduces the cost factor when wiring a building. Two pole 15 amp breakers are used for kitchen counter split receptacles.Two pole 20 amp breakers can be used for baseboard heating and hot water tanks.Two pole 30 amp breakers can be used for clothes dryers and some heating units.Two pole 40 amp breakers can be used for electric ranges.Two pole 50 amp breakers are not common in home wiring circuits. It might be used for an electric furnace or some other high current device.
