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.
AWG stands for American Wire Gage (gage is spelt gauge in British English)The larger the gauge number, the thinner the wire.
