The sizing of Transformers is based on an accumulation of all of the loads that will be connected to it. Add up all of your loads and possible loads in the future and then tell your installer the figures and they will use these to calculate the size of the transformer that is needed.
What else can I help you with?
How do you go from 208v to 230v?
You need a step up transformer unfortunately. Buy an Ugly's book electrical reference book. They're great and there is a transformer chart in there that will list the proper size or Kva that you will need according to your amperage need.
How single phase 208 works without a neutral?
There must be a 'return' connection if the load is to work. So, you cannot simply connect the load to the line conductor and expect it to work. It must also be connected to the neutral. In some circumstances (e.g. with no ground-fault interrupter installed), it will also work if you connect it to earth (ground) instead of the neutral, but this will contravene most electrical regulations and should NEVER be done.
How do you wire a 208V motor with a 120V light bulb in the same circuit?
First off, I'm going to have to quore Robert here: (LIFE SAFETY WARNING! [disclaimer] Electricity is dangerous! You can be injured or killed! Improper installations can cause fire, injury and death! Should you be doing this yourself?) This is one of those questions - if you know this little, you shouldn't be doing what you are planning... No disrespect intended, but this is SO basic that it suggests you have not studied the subject at all! There are many good reference books and course books to study from. Unless you have 208V 3 phase power, you cannot make this work. You cannot power a 208V motor off a 120V supply. Since it is 208V, it is likely that it is a 3 phase motor. That means it has 3 hots. Check the specification plate on the motor, it should say how to wire it. With 208V 3 phase you should be able to get 120 from 1 hot phase to neutral. This means you need 5 feed wires (3 hots, a neutral, and ground) from your panel to your little light/motor contraption. Please buy a book and read up on this. It sounds like you don't know much about your system and ignorance is fatal (and not necessairly fatal to you) with electricity.
What transformer do you need if you have primary voltage of 600 3 phase and require 240 volt 1 phase?
A single phase 600 to 240 Volt transformer using two phases of the three phase primary.
How do you design a transformer with three phase 400v input and single phase 2000v output?
By design are you going to wind the transformer yourself? In your design you need a 5:1 ratio. On the output side of the transformer any two legs of a three phase transformer is considered single phase voltage. Good luck on your project.
Can you feed a 208v 200amp panel from 480v 20amp circuit?
Not directly, you would need to transform 480v circuit to 120v with a transformer first.
How can you get 240V single-phase power from a 240V 3-phase service Can you just connect to two poles of the 240V 3-phase service?
If the 240V 3-phase service is 240V phase-to-phase, then you can get 240V single-phase by simply picking two phases (poles, as used in the question) and connecting the load across them. This is simply one third of a standard delta connection. If you need 120V/240V split phase, i.e. with a neutral, as used in residential services, you will need a transformer. If the service is actually a four wire "quadraplex" service, however, you will probably already have that 120V/240V with neutral connection phase available. In this case, you will need to pick the two phases correctly in order to get the proper 120V service half.

Can you convert 120v household into 220v 3 phase for a machine?
No, you cannot directly convert a 120V household outlet to supply 220V 3-phase power for a machine. You would need a transformer to step up the voltage and a suitable 3-phase power source to provide the required power for the machine. It is recommended to consult with a licensed electrician to ensure proper installation and safety compliance.

What makes a 480 motor with up down and stop 120v switch work?
I think I understand what you are asking. 3-phase motors usually are equipped with a starter or contactor, since all 3 hot wires need to be switched. The control voltage that runs the starters is 120V, because it's safer and also 120V switches and relays are cheaper. You would have a 480-120V transformer (called a control transformer) in the starter box to provide the 120V "control voltage". So the arrangement you describe would have two contactors, with two phases reversed between them. Energize one, and the motor runs forward. Energize the other, and it runs reverse. The switch sends 120V to each of the contactors, which are equipped with 120V coils.

Why the need of harmonics in single phase transformer?
Harmonics are really not needed in single phase transformers.
Why are you not getting 240v between the two hot wires?
Because they are "in-phase". In order to get 240v, you need two 120v Alternating Current lines that are 180° out of phase, that is, opposite phases. Only when one line is +120v and the other -120v will you see 240v between the wires.
How do you change over so you can plug a 120V RV plug into a 240V single-phase twist-lock receptacle?
Is the 220V plug 220V only or 110/220V? (The former will have 3 prongs and the former will have 4) If your case is the latter just use the ground, neutral, and one of the hots. This will give you 120V single phase. If the case is the former you can't get 110V off that plug.
What transformer do you need if you have primary voltage of 600 3 phase and require 240 volt 1 phase?
A single phase 600 to 240 Volt transformer using two phases of the three phase primary.

By design are you going to wind the transformer yourself? In your design you need a 5:1 ratio. On the output side of the transformer any two legs of a three phase transformer is considered single phase voltage. Good luck on your project.
