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".

∙ 12y agoThe meaning of the word ampacity is a conjunction of two words. When you want to know what the capacity of amperage that a wire will legally carry you ask what is the amp capacity of the wire or shortened down to what is the ampacity of the wire.

'Ampacity' is a North American term for the 'current-carrying capacity' of a cable. It is not used in most other English-speaking countries.

What determine the ampacity of a wire?
Conductors must have an ampacity not less than the maximum load that they are supplying.
What is the capacity of 8 gauge wire?
A #8 copper wire with an insulation factor of 75 or 90 degrees C has an ampacity of 45 amps. A #8 wire with an insulation factor of 60 degrees C has an ampacity of 40 amps.
Maximum current for 24 gauge wire?
ampacity is 1.3 Amps
You have 3 sets of conduits with 6 500MCM conductors in each one what is your ampacity?
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.
Can you run two 60 amp sources in parallel to get 100 amps out?
No they can not, because the electrical code states that wires in parallel can only be 1/0 AWG and larger. The ampacity of 1/0 wire is 150 amps. The ampacity of a wire for 60 amps is #6 which is much smaller that 1/0 wire.

Allowable ampacity of 10 copper thin wire rated at 75 degree Celsius?
Isn't it 35, according to the NEC 310.15(B)(16) Table.
What is the aluminum wire equivalent to?
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.
Can 12-2 wire be used where only 14-2 wire is required?
Yes the ampacity of #12 is 20 amps whereas the ampacity of #14 is 15 amps, so you are well within the range using #12 wire.
What is larger 12 gauge wire or 20 gauge wire?
Yes, a #12 AWG conductor has a greater diameter than a #14 AWG conductor. A #12 conductor has an ampacity of 20 amps whereas a #14 conductor only has an ampacity of 15 amps.
How do you run 4 prong 240 volt outlet?
you must run the proper size wire based on the ampacity needed, wire must have four conductors including the gound
Can 14 gauge wire carry 220 volt?
Wire guage is used as a measurement for the ampacity of the wire. # 14 wire is allowed 15 amp to be applied to it. Voltage is governed by the insulation factor of the wire. The three standard insulations are for 300V, 600V and 1000 volts.
