You can reduce the breaker size because that limits the current that can reach the main panel. There is no safety issue other than the significant danger in an unskilled person changing out a main breaker.
It depends on what else you are running in the house. Add up your amperage to see if it is more than the 125amp rating. Which should be below 105 amps constant to keep from overheating the main breaker. If you are not running a big central ac system or a electric oven and water heater you should have no problem running the hot tub.
All depends on how big your main breaker is and what size wire you are using,one 20 amp outlet needs #12 wire not more than 50feet away from main breaker
The amperage capacity of the main bus bars and the connection of the main breaker to the bus bars.
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.
If the main breaker is with out any fluid or oil then technically it is no problem. However the operator may get confused while using it, particularly during an emergency situation, he might actually put on trying to put off, which might lead to serious problems.

When I went to a 100 amp service I could not find a 100 amp. breaker in stock. I used a 60 amp. breaker and have never blown it. The 200 amp you are using can handle up to 200 amps, but if you use a smaller breaker it will only handle up to that amperage. 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.
The maximum amperage capacity of the main breaker in a 100 amp sub panel with a main breaker is 100 amps.
The recommended size for a main breaker in a residential electrical panel with a 125 amp main breaker is typically 150 amps.
The breaker will have a black wire connected to it. Turn off the main breaker and then disconnect that black wire from the breaker. The breaker will snap into the main bar. Remove the breaker and install the new one. Reconnect the black wire to the breaker and then install the cover and turn the main breaker back on.

No, a subpanel does not necessarily need a main breaker for proper functionality.
The wiring is like this:[[30KW Motor ---- Star Delt Starter(100A Breaker inside) ----- 200A Breaker------50A Breaker(Inside the breaker box which located inside the factory) -----100A Main Breaker]]Once I try to start the Motor, the Main Breaker trips immediately.
To replace a 200 amp main breaker in a residential electrical panel, follow these steps: Turn off the main power supply to the panel. Remove the panel cover to access the breaker. Disconnect the wires connected to the existing breaker. Unscrew and remove the old breaker. Install the new 200 amp main breaker in the same position. Connect the wires to the new breaker. Secure the breaker in place and replace the panel cover. Turn the main power supply back on and test the new breaker.
The amperage capacity of the main bus bars and the connection of the main breaker to the bus bars.
The maximum amperage capacity of a 100 amp main breaker in an electrical panel is 100 amps.
The maximum amperage capacity of a 150 amp main breaker in an electrical panel is 150 amps.
