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.

If you have a 125 amp breaker box on the pole with a 125 amp breaker going to your house and you get a hot tub that needs a 60 amp GFI breaker would that overload the box?

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.


If you have a 200A Meter Main Combo do you need a main 200A breaker in the panel?

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.
