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.
A Storm Cat 800 watt generator has a decimal rating of between 190 to 265 decibels depending on load and amperage. This is enough noise pollution to cause hearing damage after twenty minutes of exposure.
A 350 MCM aluminum conductor with an insulation factor of 90 degrees C is rated at 260 amps.
A 250 MCM copper conductor with an insulation factor of 75 or 90 degrees C is rated at 255 and 290 amps respectively
500 MCM can carry 380 Amps at 75 degrees C.
600amps
It is ok to use a fuse with a higher amperage rating and not ok to use a fuse with a smaller amperage rating why?
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.

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.
Usually the current rating for a circuit is higher than the current usually taken. This leaves a little margin for safety.
No, a fuse of a higher amperage rating will not usually have a higher melting point link. The higher amperage fuse will use a wider link or a link of larger diameter.

A 350 MCM aluminum conductor with an insulation factor of 90 degrees C is rated at 260 amps.
A 250 MCM copper conductor with an insulation factor of 75 or 90 degrees C is rated at 255 and 290 amps respectively
500 MCM can carry 380 Amps at 75 degrees C.
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.
