There are two distinct questions here. To determine the wire size to carry 15000 volts the circuits load amperage must be stated.
The wire size for a 550 amp service is, an 800 MCM copper conductor with an insulation factor of 90 degrees C. This conductor is rated at 555 amps. Parallel 250 MCM will give you a total capacity of 580 amps. A triple run of 2/0 will give you a total capacity of 585 amps.

How do you solve for the size of wire when the given is kva?
The V stands for volts and A is amps. If for example you have a 12kVA device and are running off a voltage of 120 volts then Amps = 12000/120 = 100. You then use the calculated amps in a wire size table to get the correct size.
Will 2.5mm wire conduct 240 volts?
You size wire by the current. Various insulations are rated for voltage, temperature and the medium where the wire will be run.
What size wire do you need for 650 watts?
To answer this question a voltage needs to be stated. Wire is sized by the amount of amperage the load takes. W = Amps x Volts. Amps = 650/ volts.
What size ground wire for 100a service?
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
What is the cable size for 90 kw motor?
Depends upon the voltage. The formula for amperage or (wire size) is Watts / Voltage. If the voltage is 220 volts, then the amperage would be over 400 amps. This would require a large wire size to run it. If it were 440 volts, the amperage would be 1/2 or 200 amps. That would require a smaller wire size. As the voltage goes up, the amperage goes down. At a thousand volts, the amperage would only be 90 amps. A wire gauge or size of a #2 would carry 90 amps for small distances.
What size breaker needs to be installed for 15000 watt 240 volt heater?
15,000 watts at 240 volts will use 62.5 amps. Therefore you will need to use AWG #3 wire on a 100 amp breaker.
Will 14-2 wire push 15 amps at 80ft?
80 feet of 14 AWG wire has a resistance of about .2 ohms. So at 15 amps the voltage drop across the length of wire is about 3 volts. With 120 volt service, this should be fine. If you up the wire size to 12 AWG, the voltage drop would be 1.9 volts.
What size copper wire should you use for 240 volts 200 amps?
3/0 wire 3/0 wire
What size of current does the 1.5mm wire carry?
A 1.5 mm wire is rated at 13 amps at 120 volts.
Is there a voltage carrying limit of wire?
Yes it depends on many variables such as what the wire is made of the size of the wire whether the wire is a multi strand wire. What governs the amount of voltage a wire can carry is the insulation that is wrapped around the wire. Like wire with ratings of 300 volts, 600 volts and 1000 volts these are the highest allowable voltages that can be applied. A wire that is rated for 300 volts is good for 120 volts, 240 volts and 277 volts. At test research facilities, insulation is tested to destruction. The label that is given to the wire insulation as a result of the tests is the highest safest voltages that can be applied to that particular type.
What wire size do you need for a 3phase 90amp 60hz 220v?
Wire size is based on the amperage capacity of the service it is feeding. You tell me the service amps and I can tell you the wire size.
How many amp service do you need to handle 450 volts?
This depends solely on the load you might need a 15 amp service or a 1200 amp service. To find out look at the installation instructions and it will tell you what size the service supply needs to be. Watts = Amps times Volts Amps = Watts divided by Volts Volts = Amps divided by Watts Example 1500 Watt unit will pull 12.5 Amps at 120 Volts or 1500 Watt unit will pull 3.26 Amps at 460 volts or A 460 volt unit rated for 34 amps will be using 15.64 kWh or 15,640 Watts Also the higher the voltage, the lower the Amperage, however, the wattage will stay the same <<>> The question is asking about two different values. Voltage is an insulation value whereas amperage is a conductor size. The basic insulation values are 300, 600 and 1000 volts. In the question on this service, a insulation factor of 600 volts will be used for the conductors. The amperage of a service is based on the connected load that needs to be supplied. The load can be an individual load or as in a distribution panel a variety of loads. At 460 volts, the service can be either a three phase service or a single phase service. Once the load amperage has been established, the wire size for the service can be calculated. Once the wire has been sized, the breaker used to protect the wire from being overloaded will be calculated.

Can two thin wire can hold 220 volts?
Any voltage can be applied to any size wire. It is the load amperage that the wire must be sized for. The larger the amperage, the larger the wire size must become.
What size ground wire needed for 75 amps at 208 volts?
#8 copper
What size wire do you need for 2HP motor with 120 volts?
12/2 with ground.
