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.
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.
What is current carrying capacity for 300mm2 cable?
The nearest equivalent in AWG is 600 MCM which is 304 mm squared. A 600 MCM copper conductor with an insulation factor of 75 or 90 degrees C rated at 420 and 455 amps respectively.
What wire size should you use for 600 amps?
The wire size for 600 amps on a single wire 1250 MCM. A 1250 MCM copper conductor is rated for 645 amps with an insulation rating of 90 degrees C. This size of wire is too large to handle easily when it comes to the terminations. A service requiring 600 amps is usually paralleled or tripled which reduces the wire size which makes the wire much easier to handle. For a parallel service two 350 MCM cables are used and for a triple parallel run three 2/0 conductors are used. These conductors all have an insulation rating of 90 degrees C.
What size service ground is needed for a 350 parallel service?
From the question it is hard to establish whether the service size is 350 amps or the service conductors are 350 MCM in parallel. If the service is 350 amps, the grounding conductor is #3 bare copper wire. Parallel 350 MCM conductors will allow for a 600 amp service. The grounding conductor for a 600 amp service is a #1 bare copper wire.
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.
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 wire do you need for 900 amp?
That would need a busbar, an aluminium one with a cross section of 1 cm by 9 cm (or larger). <<>> A 600 MCM copper conductor with an insulation factor of 90 degrees C is rated at 475 amps. A 300 MCM copper conductor with an insulation factor of 90 degrees C is rated at 320 amps. A 3/0 copper conductor with an insulation factor of 90 degrees C is rated at 225 amps. These size wires can be installed in parallel 600 MCM, tripled for 300 MCM or grouped in four 3/0 wires groups to achieve the amperage required. Special parallel, three barrel and four barrel lugs have to be used to make the connection to the required load.
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.
