How do you read breaker box amps?
The main breaker will have marking indicating size of electrical service, or if it is a fuse system....the fuses will have current ratings. If it is a subpanel, it might not have a main breaker. In this case you would have to look in the panel that the feed is coming from and find the size of the breaker that is feeding it. In either case you must look for the manufacturer's label that will have the maximum current the panel can handle, make sure the breaker feeding the panel doesn't exceed this rating.
What size breaker is needed for a 220 v hot water heater?
The wattage of the water tank is needed to size the breaker and the wire to feed the tank.
What is the smallest size circuit breaker found in the normal home?
The biggest circuit breaker in any home is the main breaker located in your main breaker panel that is installed where your electrical service cable comes into your home.
Is 60 amp breaker good for 225 stick welder?
The 225 amps is the secondary output amperage. Look on the machines nameplate to find the input amperage. It is that amperage that is needed to size the feed wire and there the breaker size. When you find that amperage you may want to re question the breaker size.
What size in amperage circuit breaker should be used for a pool pump?
The sizing of the circuit breaker and hence the wire size to feed the pump are all dependant upon the amperage of the pump. This question can not be answered without that information.

How can you tell what your home amp service is?
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.

Can you downgrade from a 125amp main breaker to 100 amp breaker using the same box?
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.
Is the main circuit breaker is a sum of the sub circuit breaker?
Typically yes because that is what makes sense. However, the subpanel could have the same size breaker as long as the panel were rated for that amperage and the wire sizes were appropriate.
