What else can I help you with?
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.
What is average 208-230 voltage?
208V is one standard in the US for light commercial 3-phase power. It measures 208V phase to phase and 120V phase to neutral. 230 (or 240)V refers (in the US) to the common service supplied to residential. It is single-phase, with two hots and a neutral; 120-0-120. One hot and the neutral (120V) is used for receptacles and small appliances, both hots (240V) are used for large appliances, such as stoves, ovens, air conditioning, and water heater.
What is cheaper to operate 120v motor or 220v same horsepower?
220 volt will use less energy.
What rating is called for in a non fussed disconnect switch between a Automatic Transfer Switch with a 400amp breaker 120 208v system and a generator that outputs 120 208v 3ph capacity 100KW 125KVA?
400 amps
Can you run 125v air conditioner on 120v house current?
Yes ,it's the same voltage.You have a +-5% of voltage range
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.
What is low voltage transmission?
In the supply industry it refers to circuits of below 1000 volts. Common voltages used are 120v, 208v, 230v, 240v, 277v, 400v, 415v, 480v.

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 is the output of the control transformer?
Depends on what the voltage is being stepped down in that particular control transformer. Control transformers usually step down a voltage of 480/208v to 120V. The 120Volts can now be used in safer manner to "control" start/stop buttons, and other components that are only built to run on 120V
I need a 120V 208V 3 phase What size of 3 phase transformer do you need?
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.
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 many volts does a freezer use?
A freezer you would find in a residential application would be 120V. You may find commercial freezers running on 240V or 208V.
Can you connect a 240V ballast to 208V line service?
It is not recommended to connect a 240V ballast to a 208V line service as this can potentially damage the ballast and create a safety hazard. It is best to use a ballast that is specifically designed for use with a 208V line service to ensure safe and proper operation.
How does 120Volts single phase convert to 220Volts 3 phase when the 3 phase voltage should be 208Volts ie 120V x sq route of 3 equals 208V?
If you get 220 volts instead of 208 volts it means that the transformer supplying the circuit is wired in Delta with one of the legs center-tapped to ground.
Does the neutral wire size and the hot wire size have to be the same on a 120v 208v bank?
If the load is perfectly planned AND purely resistive the neutral current would be zero in a 3-phase 4 wire circuit. But that is extremely rare. Before nonlinear loads (fluorescent lighting, computers, dimmers, variable speed drives etc) 1/2 size neutrals were often used but now full size neutrals are used to cope with the increasing levels of 3rd harmonics resulting from modern equipment, which can lead to neutral currents approaching or even exceeding the phase current. With very high levels or harmonics, double size neutrals are being used in places
