The wire can be as big as you want to carry 6 amps. As a comparison, the smallest home wiring power circuit uses a #14 size wire and it is rated for 15 amps.
In the UK a wire of 0.75 sq. mm is rated at 6 amps for portable appliances with occasional use. For a permanent installation a cable of 1 sq. mm. or more should be used. House wiring uses 2.5 sq. mm cable in a ring circuit to supply power sockets.
4.0 square mm
No you need at least a #6. Depending if it is a motor load it may even be higher that a #6. #10 wire is only reated at 30 amps. #8 wire is rated at 40 amps.
Wire sizes and ampacity are regulated by code. # 14 wire 15 amps, #12 wire 20 amps, #10 wire 30 amps, #8 wire 40 amps, #6 wire 60 amps. These are the most common, a slight variation in amperage depending on the insulation factor.
Maximum amps for chassis wiring : 101 amps Maximum amps for power transmission : 37 amps Reference : http://www.powerstream.com/Wire_Size.htm
55 <<>> A #6 copper conductor with an insulation factor of 75 or 90 degrees C are both rated for 65 amps.
At 120 Volts you would draw about 42 amps. At 240 Volts it would be about 21 amps. For 120 Volts you would need 6 AWG and for 240 Volts you would need 10 AWG.

A #4 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 85 amps. This size wire will also be the same for a load amperage of 68 amps as the next wire size smaller #6 is only rated at 65 amps.
The main insulation factors of the wiring used in every day use are 60, 75 and 90 degrees C. A #6 wire can be any of the above. The higher the insulation factor, the higher the ampacity of the wire becomes. For a #6 wire the amperage is 60 C - 55 amps, 75 C - 65 amps and 90 degrees C - 65 amps.
# 6 will carry about 40 amps more than a number 12
