A 225 amp load will physically not be able to tie into a 15 amp breaker and a duplex receptacle as you can not get a 3/0 wire under the breaker and receptacle terminal screws.

What is Ir value of a circuit breaker?
Ir is the Interrupt rating of the circuit breaker. It is the maximum amount of current the breaker can withstand without damage. In a molded case breaker's electronic trip mechanism, Ir is the continuous current rating that you select, to trip the breaker at a given overload current. Standard requirements request that the breaker trips at 2 hours with an overload of 135% and will trip as a function of I squared x time selected for higher currents.
Can you switch a 30 amp breaker to a 50 amp?
Yes you can use a 60 amp breaker to feed a 100 amp sub panel. The wire from the 60 amp breaker must be #6 or larger. You will not be able to draw the maximum 100 amps from the panel you will be limited to 60 amps.
How do you upgrade a 30A outlet to a 50A outlet can I just change the outlet and upgrade the circuit breakers?
No. The receptacle, wiring, and breaker ratings should all be matched properly. Replacing the 50A receptacle with a 30A receptacle isn't a problem, since the wire should be rated at least 50A. But a 30A receptacle should be protected with a 30A double pole breaker. The breaker only costs about $8.00, so why wouldn't you change it given you don't have to change the wire which would actually be expensive or time consuming? The fact that you mention a 50A receptacle protected by a 20A existing breaker isn't normal either. I would check to make sure the wiring is actually rated for 50A and that someone didn't just throw a 50A receptacle onto a 20A circuit. (This means your wiring should be at least #8AWG THHN Copper wire.) If you protected a 30A receptacle with a 20A breaker, the load might trip the breaker often, considering the appliance requiring a 30A receptacle probably requires about 30A. If you do not understand the work well enough to accomplish it yourself properly and safely, don't try it. Consult a professional electrician, as they are proficient enough to do it properly and safely. When working on electrical circuits and equipment, make sure to de-energize the circuit you will be working on. Then test the circuit with a definitive means to make sure it is off (multimeter with metal tipped leads, voltage tester with metal tipped leads, etc., not a non-contact tester, which is non-definitive.)
If you have a 30 amp breaker how many watts can it use?
To answer this question a voltage must be given. Watts = Amps x Volts. <<>> Answer At 115 volts ac, 30 amps equals 3,450 watts.
What is the anti-pumping scheme of Circuit breaker?
in order to stop the repetitive closure of the circuit breakers, anti pumping relay scheme is used. i.e suppose that an operator gives a close command to the breaker(via some switch), now the fault occurs, the breaker would tend to clear the fault and open the contacts.But since the operator has given the close command, it would cause closing of breaker again and again.. so anti pumping relay is used to ensure that this does not happen!
How do you calculate the dc circuit breaker rating for a given kw?
the given kw Divide by the your voltage
How can you determine if you have 110 or 220 volts?
Most residential service in USA has both. In the USA 110 to 120 volts is a given and it would be very unusual not to have 220 to 240 volts. It can be easily tested at main panel with a volt meter. Or as an alternative call your power company.
What is a difference between 10KA and 22KA circuit breakers?
The previous answer is incorrect, and I would advise that user to not give out information if they are going to give completely misguided information. The interrupting rating of a breaker is the maximum current that the breaker is designed to handle, at the breaker's rated voltage, before damage will occur to the breaker. A breaker will trip at FAR LESS than the interrupting rating, but it is extremely dangerous to expose the breaker to any situation where it will have more than the rated interruption current. the breaker is designed for. The reason some breakers are rated at 22kA instead of 10kA is because they typically have far larger conductors hooked up to them, so with the lowered impedance on the circuit there is more of a chance for the breaker to experience a higher fault current at the breaker. So electricians install 22kA breakers to handle the higher "available fault current."
What is the definition of circuit breaker?
An electrical switch which automatically shuts off when amperage get above a given value.
What gauge wire do I need to run 250' to an outdoor gfci receptacle?
This is a voltage drop question. To answer this type of question a circuit voltage and the circuit load amperage must be given to calculate an answer.
What is the Function of circuit breaker?
The purpose of a circuit breaker is to open the circuit in the event of an overload. Wires/conductors are only rated for a specific Amperage. If this amperage is exceeded the conductor/wire begins to heat up and given enough time it becomes a fire hazard. For instance a 15 amp breaker will trip once the Amps drawn through that circuit exceed 15 amps. The short answer is to keep you safe.

Definition for time current curve?
It is the relationship between current and time on a circuit breakers opening. When the circuit breaker needs to open in given "windows" of amps and time. They should intersect on the curve to indicate proper circuit breaker functioning. The timing and current value should coincide with each other, per manufacturers specifications. Each breaker differs.

Why use an enclosed circuit breaker?
To protect the wiring from overheating and catching on fire.AnswerThe term, 'switchgear', describes a variety of switching devices including circuit breakers and isolators (disconnects).A circuit breaker is an overcurrent protection device. Overcurrents are overload currents (due to too much load for a given circuit) or short-circuit currents (due to electrical faults).

Can I use my old central air conditioner's circuit to power a new hot tub?
The capacity of the breaker in amperage and the size of the wire connected to the breaker of the A/C circuit must be stated along with the total load of the new hot tub. Only then can an answer be given.
