For the common small cables used in domestic electricity the maximum current for a short time is 10 amps per mm2, reducing to 8 A/mm2 for loads that are on for 1½ hours per day, to 4 A/mm2 for loads that are on for 6 hours/day, and to 2 A/mm2 for continuous loads. Currents higher than the above will give excessive energy losses in heating the cables.
12 swg current carrying capacity
570amps on 3phase 415volts
The larger in diameter the wire is, the larger the current carrying capacity the wire has.
in air it will be 665Amps.
It can carry upto 100 Ampere.
The current capacity varies depending on the length and diameter of the wire
if you know the gauge of the wire you can learn its current carrying capacity
No, a copper wire that is not carrying a current will not be attracted to a magnet. Copper is not a magnetic material, so it does not interact with magnetic fields in the same way that magnetic materials like iron or nickel do.
I can say it is 29 Amps.But again it depends on the cable length.The more the cable length is the less the current carrying capacity will be.
To answer a current carrying capacity question the size of the wire has to be stated.
A 35 sq mm copper wire with an insulation factor of 75 or 90 degrees C is rated at 115 and 120 amps respectively.
