It is a North American electrical term. It is a combination the words amp and capacity rolled into one word "ampacity". When talking about how much amperage a wire can legally draw, it is referred to as the wire's "ampacity".
Conductors must have an ampacity not less than the maximum load that they are supplying.
The ampacity of 500 MCM R 90 degree wire is 395 amps. Don't forget to de-rate the wire as there are more that three conductors in a raceway.
Yes, that is correct. Ampacity, which is the maximum amount of electricity a wire can safely carry, increases as the wire diameter increases. This is because a thicker wire has less electrical resistance, allowing more current to flow through without overheating the wire.
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.
The current carrying capacity of a wire is dependent on the material and insulation of the wire. Without this information, it is difficult to determine the exact amperage 35mm2 wire can carry. It is recommended to refer to the wire manufacturer's specifications or a wire ampacity table for this information.
The ampacity rating for 18AWG wire is typically around 16 amps.
The ampacity of 18 gauge wire is typically around 16 amperes.

Isn't it 35, according to the NEC 310.15(B)(16) Table.
Yes, that is correct. Ampacity, which is the maximum amount of electricity a wire can safely carry, increases as the wire diameter increases. This is because a thicker wire has less electrical resistance, allowing more current to flow through without overheating the wire.
In the electrical trade aluminum wire is equivalent to copper wire as it is also used to carry current. To carry the same current as copper wire aluminum wire is up sized to meet the same ampacity.
The ampacity of a No. 3/0 THHN copper wire, under typical conditions, is approximately 200-230 amps. This value can vary based on factors such as ambient temperature, installation conditions, and whether the wire is in conduit or not. Always consult the National Electrical Code (NEC) or a professional for specific applications.
