The answer depends on several factors: Most electrical codes in the United States are based on the NFPA. Some areas may follow a different standard. Ampacities of conductors are arranged in the NFPA in several charts depending on the installation criteria. In addition the charts have correction factors. The several factors that need to be identified are: What is the conductor made out of: copper, aluminum or other?
Is it in a raceway, on a messenger, in free air, or a cord?
If in a raceway, is there more than 3 current carrying conductors?
Is it high-voltage (above 600) or low voltage?
What type isulation is being used?
What is the allowed voltage drop?
What is the ambient temperature?
As you can see there is no easy answer. However, on a typical installation using copper wire for under 600 volts, the size is in the range of 4/0
For 2000 amps, you would typically use a wire size of 400 MCM (thousand circular mils) or larger to safely carry that level of current. It is important to consult local electrical codes and a professional electrician to determine the exact wire size needed for your specific application.
Answer for USA, Canada and countries running a 60 Hz supply service.
A 000 copper conductor with an insulation factor of 90 degrees C is rated at 225 amps.

Answer for countries in Europe and other world areas running a 50 Hz supply service.
cable size to be used is 120sqmm.
if cable is laid in ground then it will carry-240Amps
if cable is laid in duct then it will carry-195Amps
if cable is laid in air then it will carry-230Amps
4C 400 sq mm copper cable run in parallel.

In North America to obtain feeders for 2000 amps you could use a triple run of 1500 MCM cable that will give you 2115 amps. A quad run of 700 MCM cable that will give you 2080 amps. A parallel run of 5C at 500 MCM cable that will give you 2150 amps. A parallel run of 6C at 350 MCM cable that will give you 2100 amps. Over that I have never seen lugs that will carry more that 6 conductors.
A 3/0 copper conductor with an insulation factor of 90 degrees C is rated at 225 amps.
A 2/0 copper conductor with an insulation factor of 90 degrees C is rated at 195
amps.
In the CEC for 3-wire 120/240 volt conductors used for single dwellings, the allowable ampacity for size 2/0 AWG shall be 200 amps.
In the US you need 2/0 ("2 ought") copper for residential and 3/0 copper for commercial.
A 3/0 copper wire with an insulation factor of 75 or 90 degrees C is rated at 200 and 210 amps respectively.

What size wire do you need to run to an air conditioner that has a maximum breaker size of 40 amps and a minimum circuit size of 25.3 amps?
You would need to use a wire size that is rated for at least 40 amps to be safe and to meet the requirements of the air conditioner. A common wire size for this application would be 8 AWG copper wire, which is rated for 40 amps.
What size wire should you use for a 20 amp breaker?
For a 20 amp breaker, you should use a wire size of 12 AWG for standard residential wiring. This wire size can safely handle the current load without overheating. Make sure to always consult local electrical codes and regulations for specific requirements.
What size wire should you use for a device operating on 240 VAC pulling 22 amps?
For a device operating on 240 VAC pulling 22 amps, you should use a wire that is at least 12-gauge in size to ensure it can safely handle the current without overheating. It's always a good idea to consult with a licensed electrician to determine the appropriate wire size and type for your specific application.
What size breaker and wire for 2000 watt heater?
A 2000 watt heater draws 8.3 amps on a 240 v supply, so the cutout should be set to 10 or 12 amps. <<>> In North America a 2000 watt baseboard heater will be fed with a two pole 15 amp breaker. A two wire cable of #14 copper will be used to connect the supply voltage to the heater.
What is the Minimum branch circuit wire size in a dwelling?
The minimum size home wiring is #14 AWG, the rating for that size wire is 15 amps.
What size copper wire should you use for 240 volts 200 amps?
3/0 wire 3/0 wire
What size circut breaker for 10-2 wire?
A #10 wire has the capacity for 30 amps. No breaker larger than 30 amps should be used to protect the circuit.
What size wire do you need to run to an air conditioner that has a maximum breaker size of 40 amps and a minimum circuit size of 25.3 amps?
You would need to use a wire size that is rated for at least 40 amps to be safe and to meet the requirements of the air conditioner. A common wire size for this application would be 8 AWG copper wire, which is rated for 40 amps.
What size wire should you use for a 20 amp breaker?
For a 20 amp breaker, you should use a wire size of 12 AWG for standard residential wiring. This wire size can safely handle the current load without overheating. Make sure to always consult local electrical codes and regulations for specific requirements.
What size wire do you need for 15 amps?
AWG 10.
What size amp circuit breaker should be used for a geyser?
Depends on how many amps it pulls and the size of the wire in the circuit.
What is amp size for 14 wire?
15 amps.
What size wire for 250 amps?
15mm approx.
What size wire should you use for a device operating on 240 VAC pulling 22 amps?
For a device operating on 240 VAC pulling 22 amps, you should use a wire that is at least 12-gauge in size to ensure it can safely handle the current without overheating. It's always a good idea to consult with a licensed electrician to determine the appropriate wire size and type for your specific application.
What wire size is good for 100 amps?
# 4 copper wire short distance.
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.
What size breaker and wire for 2000 watt heater?
A 2000 watt heater draws 8.3 amps on a 240 v supply, so the cutout should be set to 10 or 12 amps. <<>> In North America a 2000 watt baseboard heater will be fed with a two pole 15 amp breaker. A two wire cable of #14 copper will be used to connect the supply voltage to the heater.
