Different AWG (American Wire Gauge) wires have different diameters, cross-sections, and allow only a limited number of amps to flow through them. To adequately figure out what size AWG wire you need, you require at least a wire gauge chart.

6 Gauge Wire
diameter of 4.115 mm. That’s about 1/6 of an inch.
6 AWG wire is big enough to have 65 amps At 75°C
7 Gauge Wire
rarely used 3.665 mm diameter

With 8 gauge wire diameter of 3.264 mm.
50 amps at 75°C
9 Gauge Wire
9 gauge wire normally used as mechanical purposes
10 Gauge Wire
10 AWG gauge wire
Rated ampacity 35 amps at 75°C; this is the
11 Gauge Wire
Since it’s not customarily used as an electrical wire, it has no rated ampacity.

4/0 Gauge Wire Details (0000): Amps, mm, mm2, 4/0 AWG Wire Suggestion
4/0 or 0000 AWG gauge wire is the thickest wire used in the standard AWG system. It is one of the two AWG wires that have a 10+ mm diameter (4/0 AWG wire to mm equals 11.684 mm).
Ampacity-wise, the 4/0 AWG gauge wire can handle the largest amount of current of any AWG gauge wire. At 75°C, the 4/0 copper wire ampacity is 230 amp (with 195 amps and 260 amps at 60°C and 90°C temperature, respectively).
3/0 Gauge Wire Details (000): Amps, mm, mm2, 3/0 AWG Wire Suggestion
The diameter of the 000 gauge wire is 10.405 mm.
Most 3/0 gauge wires with 85.00 mm2 cross-section are rated up to 600 volts.
Similar to the 4/0 gauge wire, the 3/0 AWG gauge wire is used for welding and for drawing the current (and power) out of large 12-volt or 24-volt batteries.
2/0 Gauge Wire
(00 Gauge Wire)
2/0 AWG gauge wire 9.266 mm thick AWG wire.
2/0 copper wire at 75°C is 175 amps, and the 00 AWG wire is custom used as a 150 amp wire size
1/0 Gauge Wire Details
1/0 gauge wire is commonly referred to as 0 gauge wire and has a diameter of 8.251 mm.
At 75°C, the 1/0 copper wire ampacity is 150 amps; essentially, the 1/0 W wire is a 150 amp wire size. At 60°C, it can handle up to 125 amps, and it can handle up to 170 amps at higher temperatures (90°C).
