The resistance for 400 ft. of 10 AWG copper is .4 ohms. This would be a voltage drop of (.4 x 20) or 8 volts. For 120 VAC service this is a 6% which is a bit high. At 240 volts it is 3%. At 8 AWG the resistance is .251 ohms which will give you better performance.
A 10 gauge copper wire can carry 20 amps of current over a 400 ft distance without significant voltage drop, as long as the wire is properly installed and meets electrical code requirements. It is recommended to consult local electrical codes and consider factors such as ambient temperature and insulation rating to ensure safe and efficient operation of the circuit.

What size wire is needed for a 200 amp residential service panel?
A 3/0 copper or 4/0 aluminum wire is typically used for a 200 amp residential service panel. It's important to consult the National Electrical Code (NEC) and local building codes to ensure compliance and safety. It's also recommended to consult with a licensed electrician for guidance on specific wiring requirements for your installation.
What size wire needed for 200 amp service 400 feet away direct buried single phase 240 volt 3 wire?
Assuming you are working with 240v, you need 4/0 copper conductors.
What wire size to use from breaker box to earth ground rod?
We recommend using a #6 copper wire for the connection between the breaker box and the earth ground rod. This size wire is commonly used for grounding purposes and is sufficient for carrying the electrical current safely to the ground rod. Be sure to consult with a qualified electrician to ensure the proper materials and installation for your specific situation.
400 amp service what size wire?
For a 400 amp service, you would typically use 500 kcmil copper wire or 600 kcmil aluminum wire for the main service conductors. It's important to consult with a licensed electrician and check local electrical codes to ensure the correct wire size is used for your specific installation.
What wire size should you use for 2000 amps?
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.
What size wire to run 400 ft from main panel need 60 amps?
Use AWG # 4 copper and you will have a 2.6% voltage drop which is acceptible.
What size conductor is needed to carry 25 amps 120 volt AC over 400 feet?
A #4 copper conductor will limit the voltage drop to 3% or less when supplying 25 amps for 400 feet on a 120 volt system.
How much current does 300 sq mm cable carry?
A 228 sq mm conductor equates to 450 MCM. A conductor of 450 MCM is not a standard AWG wire size. A standard 400 MCM will carry 380 amps. A standard 500 MCM will carry 430 amps. Difference between 400 and 500 MCM amperage's is 50 amps. Transposing between the two amperage's of 50 amps will be 380 + 25 = 405 or 430 - 25 = 405 amps. This is a very rough calculated answer for the question.
What is the weight of 400 mcm copper wire per foot?
500mcm 37 strand copper wire = 1.544lbs/ft.

400 amp service what size wire?
For a 400 amp service, you would typically use 500 kcmil copper wire or 600 kcmil aluminum wire for the main service conductors. It's important to consult with a licensed electrician and check local electrical codes to ensure the correct wire size is used for your specific installation.
What does 400 mcm copper wire way per foot?
400 MCM (thousand circular mils) copper wire weighs approximately 1.51 pounds per foot.
What gauge of service wire for a 400 Amp single phase servce?
A 600 MCM copper conductor with an insulation factor of 75 or 90 degree C is rated at 420 and 455 amps respectively. This is very large diameter wire to handle. The best way of wiring this service is to use parallel runs. A 3/0 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 200 and 210 amps respectively. So depending on the insulation of the wire that is used, a parallel wire configuration will give you a total of 400 at 75 degrees C or 420 at 90 degrees C.
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 wire size should you use for 2000 amps?
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.
