20amps but Voltage at end of cable will drop. Not a problem for incandescent lights but might be a problem for motors and electronics. Generally increase wire size to next larger size for long runs, I.e. go to 10# wire. This does not factor in heating in wire under heavy load, but that is generally not a factor unless tightly enclosed.

Maximum current for 24 gauge wire?
ampacity is 1.3 Amps
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.
What is the amp rating of NM wire?
The ampacity or amp rating of all wire is rated by the size of the wire. NM (non-metallic sheathing) wire is no different. In household wiring 14 gauge wire must go on a 15 amp breaker/ 12 gauge goes on a 20 A and 10 gauge goes on a 30 Amp.
What determine the ampacity of a wire?
Conductors must have an ampacity not less than the maximum load that they are supplying.
What is Wire ampacity?
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".

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.
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.

Can you wire 10 Gauge and 12 Gauge in the same circuit?
Yes but there are two stipulations, one that the join or splice must be made in a junction box that is accessible and has a removable cover and the second stipulation is that the breaker that is supplying the power can not be larger that the smallest conductor. In this case no breaker larger that a 20 amp breaker as #12 wire is only rated at 20 amps..
What determines the ampacity of wire?
Conductors must have an ampacity not less than the maximum load that they are supplying.

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.

What is the maximum current recommended for 30 gauge copper wire?
Sorry, there is no such wire size as "30 gauge" in the AWG (American Wire Gauge) system. For the ampacity rating of all standard conductor sizes, go to Table 310-16 of the National Electric Code. If you mean what wire size will carry 30 amps then a #10 copper wire insulation rating of 90 degree C is rated at 30 amps.
Is 18 gauge speaker wire good for long wiring runs?
18 gauge wire is good for wiring speakers over long runs. It is better to buy the best shielded wire to reduce possible interference.
Can you double up on insulated wires for greater ampacity?
According to the 2008 National Electrical Code, the smallest wire that can be run in parallel is a 1/0 AWG (American Wire Gauge). If the wire you are using is smaller than a 1/0 AWG, you will need to increase the size of the wire to handle the amperage (Table 310.16 of the NEC).
