Wire size is governed by amperage not voltage. Voltage is an insulation factor when talking about wire. Add up the amperage of fixtures you want in the circuit. Once that is found then the size of the wire can be calculated.

What is the required wire size for a 230 feet run 480 volt 100 amp?
Depends on length. The more length, the more resistance.
How is the total load in volt-amperes for lighting purpose determined?
LxW of building x 3 volt amps per sq. foot
What size maximum level of primary-only overcurrent protection is required for a 600-volt transformer with a primary current rating of 54 amperes?
100
What is the minimum required voltage for Air Conditioning?
Min 190 volt and Max 240 volt. Zaman Chittagong, Bangladesh.
How many watts of lighting is required in a 15' x 10' room?
'Lighting', or the amount of light is not measured in watts. A 'watt' is a unit of power, measurement of current drawn. Most 100 watt/110 volt lamps initially produce 1690 lumens (a 'lumen' is the measure of the total "amount" of visible light emitted by a source). A 15 foot by 10 foot room is not very big, and one or two 100 watt incandescent lamps on a ceiling light fixture on a 120 volt service can light it adequately. I mention "110 volt" as in parts of the world with 220 mains these numbers change. As the voltage is doubled, the watts required would halve for the same amount of light. In other words, all other things being equal, a 50 watt 220 volt lamp should use the same amount of power, producing the same amount of light as a 100 watt 110 volt lamp.
What is a 277 volt fluorescent fixture?
A 277 volt lighting fixture is one that is usually used in an industrial application. The reason for this is the voltage rating. A voltage potential of 277 volts is the voltage to neutral (ground) of a three phase four wire 480 volt distribution system. 480 volts / 1.73 = 277 volts. Rather than having to add a transformer to the system to provide 120 volts for lighting, manufactures produced a ballast for fluorescent fixtures that operates on the 227 volt potential.
Why 440 volt for motor and 220 volt for lighting?
The higher the voltage, the less amperage is required and is easier to supply power to the device. Motors take much more power than lighting, therefore voltages may be higher for easier transmission.
What size wire is required for a 220 volt at 54 amps?
6 AWG
Can you make a 230 volt fluorescent lamp work in a 120 volt socket?
No, do not waste your time.
Are there any safety concerns I should have about lighted pot racks?
Only if the lights in the rack are incandescent or fluorescent lamps. These use standard house 110 volt power. If you buy a rack that uses LED lighting, or add LED lighting to your existing rack, the voltage is very low and can't hurt you.
Where can you purchase a Hub system for 12 volt landscape lighting?
They are available at Landscape Lighting World!http://www.landscapelightingworld.com/Volt-Hub-System-p/9hub.htm
Is the voltage on a 120 volt fluorescent lighting circuit the same from line to neutral and line to ground?
Yes, to the precision you can measure it. If it isn't you need to check the ground to neutral bonding at main panel and check the wiring in the circuit for loose connections.
How you can calculate the ampere for fluorescent lamp with use VA?
I asked about the calculation for fluorescent lamps amperes using volt ampere, that means what is the power factor used ( according to international standard) for fluorescent lamps ?
Why a volt meter reads around 20VA on a socket when the switch is off that makes some fluorescent lamps in the house to flash?
Please re-phrase your question. A volt meter does not read volt amps.
How is the load in volt amperes for lighting purposes determined?
LxW of building x 3 volt amps per sq. foot
How is the total in volt-amperes for lighting purpose determined?
LxW of building x 3 volt amps per sq. foot
What is the required wire size for a 230 feet run 480 volt 100 amp?
Depends on length. The more length, the more resistance.
