Using the AWG for wire sizes only goes up to 4/0. After that the increases use MCM to size the wire. So your 262 MCM wire size will be same in AWG. There is no 262 MCM in the North American market place. It goes in 50 MCM increments starting at 250 MCM , 300 MCM, 350 MCM, 400 MCM right up to 2000 MCM cable.

After a certain wire size in AWG it automatically changes to MCM. The last wire size to use AWG is #1. Then it goes to one 0, two 00, three 000, and four 0000 (0 pronounced ought). The next wire size is 250 MCM. It represents M -thousand C - circular M - mils.
Any wire size after #1 on through from 1/0 to 4/0 and then starting with 250 MCM is still in the AWG wire sizing category.
177 mm squared is equal to 350 MCM AWG.
500 MCM (thousand circular mils) is equivalent to approximately 3/0 AWG (3 aught) in the American Wire Gauge (AWG) system. MCM is often used for larger conductors, particularly in industrial applications, while AWG is more common for smaller wires. The exact conversion may vary slightly depending on the specific context or wire type, but 3/0 AWG is the standard equivalent for 500 MCM.
A 350 MCM copper conductor with an insulation rating of 90 degree C is rated at 350 amps.
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.
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.
