55 amps on copper wire.
The normal current capacity of 12 AWG copper wire is 20 amps.
Copper wires do not hold amps, they have a cross sectional area capacity to allow amperage to flow. In the electrical trade this is spoken of as "ampacity" of the wire. It is a combining of the two words amps and capacity. A # 2 copper wire with an insulation factor of 60, 75 or 90 degrees C is consecutively rated at 100, 115 and 120 amps.
I'm not sure if I understand your question but if you are asking if the wire number is the maximum amperage (current) it can hold the answer is NO. For example #8 copper wire will allow much more current (before melting) then #12 copper wire. Generally the higher the wire number the less amps it can hold.
A wire is not like a bucket that holds amps but more like a pipe that lets the amperage flow through it. A # 14 wire is rated at 15 amps. Code only allows up to 80% for continuous use, 15 x .8 = 12 amps.
You are probably thinking about 1/0 wire (1 ought wire). In copper it is rated at 175 amps and in aluminum 125 amps.
101 amps for chassis wiring and 37 amps for power transmission. This is for short lengths of wire.

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.

If you mean 2/0 copper wire it is rated 175 amps. # 2 wire is 115 amps. If you are referring to 2.0 metric it is rated 15 amps.
