A 600 MCM wire with an insulation factor of 75 and 90 degrees C is rated at 420 and 455 amps respectively.
Most 400 amp services will use parallel wires on each leg to feed the circuit.
A 3/0 wire with an insulation factor of 75 and 90 degrees C is rated at 200 and 210 amps respectively.
Depends upon whether you're using copper or aluminum or some other conductor and how far you need to run it and at how many volts and what voltage drop your load can tolerate during startup inrush.
A 500 MCM copper conductor with an insulation factor of 90 degrees C is rated at 430 amps.

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 size conduit for 400 amps?
For a 400 amp service, it is recommended to use 3-inch conduit to allow for the appropriate wire size and future updates. This will provide enough space for the conductors to be pulled through without causing damage. It is important to verify the specific requirements with local building codes and regulations.
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.
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.
How many amps needed for a 3000 watt 240 volt base board heater?
A 400 watt heater can safely be used on a 15 amp circuit. The size breaker needed for a circuit is determined by the size of the wiring in that circuit. AWG #14 wire requires a 15 amp breaker. AWG # 12 wire requires a 20 amp breaker.
What size wire for 400 amp distribution panel?
For a distribution panel rated at 400 amps parallel runs of 3/0 conductors will do the job.
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.
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 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 conduit for 400 amps?
For a 400 amp service, it is recommended to use 3-inch conduit to allow for the appropriate wire size and future updates. This will provide enough space for the conductors to be pulled through without causing damage. It is important to verify the specific requirements with local building codes and regulations.
What gauge wire will you need for a 400 watt amp?
To answer this question a voltage needs to be stated. The formula needed to find the amperage is I = W/E. Amps = Watts/Voltage. Once the amperage is found, the proper size conductor to handle that current can be established. Without knowing the amperage on 400 watts a good guess would be a #14 wire. This wire size is good up to 1440 watts at 120 volts.
What will be the recommended size cable size for 400 KVA transformer?
3r x 300sq.mm Al. ar UG cable <<>> Wiring is sized by the amperage that is used by the load. The formula for amps is I = W/E. Amps = Watts (or VA)/Volts. As you can see an answer can not be given unless a voltage is stated. The lower the primary voltage the larger the amperage will be and likewise the larger the wire size will be.
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.
What will be the cable size for 300 A if the 3 phase voltage is 220 volts?
At least 50mm but with all the de-rating factors it might be 70mm that's if its 2 cable single phase non armoured clipped direct. Check out the tables dopey!!!! FYI 50 mm = 2 inches, 70 mm = 2.75 inches these are not wire sizes, sound more like cable outside diameters. Correct answer The wire size is dependant on the insulation factor on the wire. A few common insulations and corresponding wire sizes for 150 amps are - Size 0 R90 good for 155 amps, also with insulations of RW 75, TWH, TW75, good for 150 amps. Size 000 TW good for 165 amps.
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 size wire is needed for 400 amp 480 volt service?
A 500 MCM wire with an insulation factor of 90 degrees C is rated at 430. Most 400 amp services will use parallel wires on each leg to feed the circuit. A 3/0 wire with an insulation factor of 75 and 90 degrees C is rated at 200 and 225 amps respectively. The insulation rating of these conductors will be 600 volts.
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.
