How many amps is 250 MCM wire good for?
300 Amps if used for service entrance conductors. Table 310.15
What size of copper do you need for a 1250 amps rating?
There are different combination to obtain a current capacity of 1250 amps. A parallel run of #1250 MCM wires. A triple run of #600 MCM wire. The most flexible run would be with a quad run of #350 MCM wire.
What size copper wire for a run of 500 feet in parallel for a resident with a load of 600 amps single phase 240 volt?
This is a voltage drop question. A 500 MCM copper or 750 MCM aluminium conductor will limit the voltage drop to 3% or less when supplying 300 amps for 500 feet on a 240 volt system. Paralleling these conductors will allow the rating to be increased to 600 amps.
How many amps can be applied to a 400 sq mm aluminium wire?
530 amps in average conditions, more in cold weather. <<>> The closest conversion will be; 405 mm2 is equal to 800 MCM AWG. A 800 MCM aluminium conductor with an insulation factor of 90 degrees C is rated at 445 amps.
What size romex for 60 amps of service?
A 300 MCM copper conductor with an insulation rating of 90 degrees C is rated at 320 amps. Parallel the feeders to obtain a total of 640 amps. This will be acceptable as service feeders for a 600 amp service.A 400 MCM aluminium conductor with an insulation rating of 90 degrees C is rated at 305 amps. Parallel the feeders to obtain a total of 610 amps. This will be acceptable as service feeders for a 600 amp service.
Amps on a 600 mcm copper?
475 amps, per NEC 310-16. Note that this is a maximum; there are many reasons to derate the current carrying capacity of the wire.

How many amps does a wire rated at 600 have?
This answer is if you are referring to the sizing of electrical conductors in North America using the AWG for sizing. An American Wire Gauge sizing of 600 refers to the cross sectional area of the conductor.This amperage value is for a single copper conductor.A 600 MCM copper conductor with an insulation rating of 75 or 90 degrees C is rated for 690 and 780 amps respectively.This amperage value is for not more than three copper conductors in a conduit or raceway.A 600 MCM copper conductor with an insulation rating of 75 or 90 degrees C is rated for 420 and 475 amps respectively.This amperage value is for a single aluminium conductor.A 600 MCM aluminium conductor with an insulation rating of 75 or 90 degrees C is rated for 545 and 615 amps respectively.This amperage value is for not more than three aluminium conductors in a conduit or raceway.A 600 MCM copper conductor with an insulation rating of 75 or 90 degrees C is rated for 340 and 385 amps respectively.

This is a voltage drop question. A 500 MCM copper or 750 MCM aluminium conductor will limit the voltage drop to 3% or less when supplying 300 amps for 500 feet on a 240 volt system. Paralleling these conductors will allow the rating to be increased to 600 amps.
What wire size should you use for 600 amps?
For 600 amps, you would typically need at least a 250 MCM wire size to safely handle the current without overheating. It's recommended to consult with a professional electrician to determine the specific wire size needed based on the application and local electrical codes.
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 romex for 60 amps of service?
A 300 MCM copper conductor with an insulation rating of 90 degrees C is rated at 320 amps. Parallel the feeders to obtain a total of 640 amps. This will be acceptable as service feeders for a 600 amp service.A 400 MCM aluminium conductor with an insulation rating of 90 degrees C is rated at 305 amps. Parallel the feeders to obtain a total of 610 amps. This will be acceptable as service feeders for a 600 amp service.
What wire size should you use for 400 amps?
generally size 500 MCM, but there can be factors which would require up-sizing, such as high ambient temperature long run causing excessive voltage drop multiple circuits in same raceway
What size wire is required for 325 amp service?
A 350 MCM copper conductor with an insulation rating of 90 degree C is rated at 350 amps.
What is the amperage rating of 500 MCM copper conductor?
It depends on a lot of factors. Generally speaking, if the insulation is THHN then the rating is 350 amps. If the insulation is THWN then the rating is 310 amps. The ampere rating for wire depends on the temperature of the environment it will be used in, the insulation rating and the number of circuits installed in a conduit. There are also other factors to consider... like voltage drop in long runs.
