A 16 mm squared wire is equal to a #5 on the AWG scale. The electrical code book does not have amperage capacities for odd numbered wires. In North America the #6 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 65 and 75 amps respectively. A #4 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 85 and 95 amps respectively.
Depends on the type of insulation and installation method. A 1.0 sqmm circuit is generally put on a 10A breaker.

You don't really control amps directly. The two easy variables are voltage and resistance. So if you DC source produces a constant voltage, you're going to have to vary the amount of resistance in your circuit to control the amps. The relationship is as follows. V = I * R So if you want to more amps for a given voltage, lower the resistance. The extreme would be to short circuit the volt source (simply connect a wire between the voltage terminals), this allow a lot of current to flow throw your circuit.

Copper (Cu) is the most common metal used in conducting wire. If you have the money the best conductor (excluding super cooled super conductors) would be pure silver (Ag).

1 mm2 aluminium wire is not easy to buy but 1 mm2 copper wire is rated at 10 amps. Since the conductivity of aluminium is 7/12 that of copper, 1 mm2 aluminium wire would be rated at 7½ amps max (the same amount of heat is produced per metre by a current of sqrt(7/12) times that for copper).
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.
A #6 aluminium conductor with an insulation factor of 90 degrees C is rated for 55 amps.
A #4 aluminium wire with an insulation factor of 75 and 90 degrees C is rated at 100 and 105 amps respectively.
#8 RW 90 degree wire
There are zero amps in 220 wire. When you talk of 220 wire you are making reference to the insulation factor of the wire. Wire in North America is rated for insulation in increments of 300, 600 and 1000 volts. For special applications 5000 volts still has insulation on it. Then there is 7500 volt cable that is classified as concentric neutral cable which is used mostly for underground primary installations. Any voltages higher than that is bare wire. For high voltage installations it is called ACSR. Aluminium Conductor Steel Reinforced. This type of cable uses a steel center support wire and the aluminium conductors are wound around the steel to carry the amperage. This combination of steel and aluminium allow the wire to be spaced over long distances between poles or towers. The amperage classification of wire is based on the circular diameter of the wire. The larger the diameter of the wire the higher the amperage capacity. Three equations to find amps when two factors are known are; Amps = Watts/Volts, Amps = Volts/Resistance and Amps = the sq. root of Watts/Resistance.

The amps that a four gauge wire will handle will depend with the thickness of the wire. If the wire is thin, the four gauge will handle 95 amps.
