Yes you could use a 20 kva transformer in a home. Stymied as to why it would be done though. You would need at least a 100 amp service to the home to energize the transformer. Primary side of the transformer would draw 83 amps at 240 volts.
If the question was to supply the home, again yes. It would be 100 amp service equipment that the transformer would feed into.
What else can I help you with?
What would the input current be for a 275 kva transformer with 2 phase of a 480 vac in and 120 vac at 20 amp output?

Single phase 10hp motor how much kva generator needed?
10 HP is 7.46 kW theoretically, but allowing for an 0.7 power factor the kVA goes up to 10.5 kVA. Add 20% for sundry losses and you get 12.5 kVA
Up to how much years we can use a 1000 kva transformer?
It depends on the transformer design, type, cooling, maintenance, fault experiences, operating temperature, and loading (I'm sure there's other things that impact it as well). A lot of equipment is rated for 10-20ish years of operation; I would assume your transformer may fall under that. That does not mean that it is dead after 20 years though; I know of several >10MVA transformers that are 60+ years old and still in use. Some have been rewound, some have not. And it doesn't mean that it is 100% guarunteed to run for 20 years. A really bad fault with slow clearing time could cook it the day after you install it.
What is the turn ratio of a transformer if the primary voltage is 240V and the secondry is 12V volts?
240 / 12 = 20
What will be the kva rating for 20a?
To answer this question the voltage of the circuit must be stated. That is what the v in kva stands for.

What is the capacity of transformers 25kva?
The capacity of a 25 kVA transformer refers to its ability to handle a maximum load of 25 kilovolt-amperes. This rating indicates the maximum amount of electrical power the transformer can safely supply without overheating or sustaining damage. In practical terms, a 25 kVA transformer can supply approximately 20 kW of real power in a three-phase system, assuming a power factor of 0.8. This makes it suitable for various applications, including small commercial and industrial uses.
Is 2.8 kva equal to 2800 watts?
Yes, 2.8 kVA is equal to 2800 watts. This is because 1 kVA is equivalent to 1000 watts, so 2.8 kVA would be 2800 watts.
How do you find kva?
k is 1000 V is volts A is amps basic algebra kVA = (V * A)/1000 120 Volt with 20 Amp would be: (120 * 20)/1000 = 2.4 kVA
How many Apms will you get from 20 KVA?
that is depending upon the voltage

When was Transformer - Bruce Kulick album - created?
Transformer - Bruce Kulick album - was created on 2003-07-20.
Can you use a 60Hz transformer in a 400Hz low power system?
There's no problem except that the transformer will be more massive than necessary. It will work at the same voltage and current, but there is less iron loss, so the voltage rating can be increased by a maximum of 15-20% and the current rating can be increased by 15-20% also. But if this is in an aircraft or other safety-critical application, do not overrate the transformer.
Step down transformer of a specs of 110 primary to 24 v 12va CAn you used a 110v primary to 24v 20 va What is the difference between them?
Yes. The Va numbers indicate the rating of the transformer (12VA indicates that you can draw upto 12/24 = 1/2 Amps at 24 volts and 20VA indicates that you can draw about 20/24 = 0.83 Amps). Usually 20va transformer will cost more than the 12va transformer. So, unless a higher power output is required, it is adequate to use the lower rating transformer. However, you cannot go the other way - if you use a 12va transformer in-lieu of the 20va one, if the application needs more power, then you have a reliability problem. The transformer will have more loss, heat-up and then eventually burn out.
How many 12V 50W bulbs can you run on a 20-60VA transformer?
A 60VA transformer can run only one 50W bulb.
