In a residential application it would most likely be used as the breaker for the entire main electric panel or a subpanel feed.

What size breaker do you use for a 100 amp sub panel?
A 100-A sub-panel would be fed from a 100-A breaker.
What size Aluminum wire is used for ground in breaker box?
For a 100 Amp breaker panel it would be 2 AWG. For 150 Amps it would require 2/0 (2 ought) aluminum wire.
Can two 225 amp panels be fed from a 400 amp breaker?
Yes, but they obviously cannot be simultaneously loaded their maximum loads because the 400-amp breaker will blow well before that. Similarly, you can have multiple 100-amp panels fed from a 200-Amp main breaker, knowing that you will NEVER have 100 amps running in all panels at the same time.
What size amp circuit breaker should be used for 110 outlet?
The size breaker you use is determined by the size wire used in the circuit. If you use AWG #12/2 wire then use a 20 amp breaker. If you use AWG # 14/2 then use a 15 amp breaker.
What are the standard size circuit breaker amperages?
In North America the standard sizes for breakers are 15, 20, 30, and 40 amps. The 15 amp size breaker is used in general circuit wiring. The 20 amp size breaker is used for dedicated appliance receptacles, hot water tank and baseboard heating. The 30 amp size breaker is used for a clothes dryer. The 40 amp size breaker is used for the electric range.
What size breaker do you use for a 100 amp sub panel?
A 100-A sub-panel would be fed from a 100-A breaker.
What would happen if a 200 amp breaker is used in a 100 amp sub panel?
There are two things to think about here. First of all a 200 amp breaker will not physically fit into a 100 amp panel. This is so designed because the panel buss is not designed to conduct 200 amps before the current is cut off. A 100 amp rating on the panel is the maximum amount of current that the manufacturer states, that can be handled safely. Second if the 200 amp breaker is in the main panel then everything downstream from that breaker has to be rated for 200 amp conductivity. The wire size will have to be 3/0 from the breaker to the first over current device in the sub panel which will be the sub panel's main breaker. The sub panel can not be a load center but will have to be a combination panel. I doubt that the 100 amp sub panel's main breaker lugs would be large enough to connect the 3/0 cable.
What size Aluminum wire is used for ground in breaker box?
For a 100 Amp breaker panel it would be 2 AWG. For 150 Amps it would require 2/0 (2 ought) aluminum wire.
Can a 4 amp breaker be used to replace a 35 amp breaker for ac unit?
NO!
Duplex receptacle circuit given 15 amp breaker 225 amp load?
A 15 amp breaker is not sufficient for a 225 amp load. You would need a breaker that matches the load current, such as a 225 amp breaker. Using a 15 amp breaker for a 225 amp load would cause the breaker to trip immediately due to overcurrent.
What type of appliance would be use a two pole 50 amp breaker?
In North America this size breaker could be used on a welding machine. A range in the home would use a 40 amp two pole breaker.
Does a double 50 amp breaker make a 100 amp?
No, a double pole 50 amp breaker protects a 240 volt supply at 50 amps. The number that is on the handle of the breaker is the amperage that the breaker will trip at if an overload occurs on the circuit.
How much should you pay for a 100 amp breaker?
probally about 100 dollars
Can a 100 amp main have 2 50 amp breakers?
Yes, a 100 amp main panel can have 2 separate 50 amp circuits protected by 50 amp breakers. This configuration allows for two separate circuits drawing up to 50 amps each from the main panel without overloading the panel's 100 amp capacity.
If a 100a breaker keeps tripping?
If a 100 amp breaker keeps tripping there is an overload on the system.
If you have a 200A Meter Main Combo do you need a main 200A breaker in the panel?
No, a Meter Main Combo typically includes the main breaker as part of its design, so you would not need an additional main breaker in the panel. The main breaker in the Meter Main Combo serves as the disconnect for the panel.
Can two 225 amp panels be fed from a 400 amp breaker?
Yes, but they obviously cannot be simultaneously loaded their maximum loads because the 400-amp breaker will blow well before that. Similarly, you can have multiple 100-amp panels fed from a 200-Amp main breaker, knowing that you will NEVER have 100 amps running in all panels at the same time.
