It depends more on the insulation type not the voltage A very common wire type is THHN According to NEC (electrical standard popular in the USA) this type wire in size #12 is rated for 30 amps, but there is a footnote that states it can only be used for 20 amps maximum
ten gauge wire is used for high current circuits. in home wiring, 12 gauge wire is normally used. 12 gauge wire can carry a maximum of 20 amps. 10 gauge wire on the other hand, is larger and can carry more current. the maximum current capacity of a 10 gauge wire is around 30 amps. one would use this for a stove, hvac or other power hungry device's.
15 amps
Yes, 12 AWG is good for 25 Amps if copper wire.If aluminum wire, then good for 20 Amps.
The normal current capacity of 12 AWG copper wire is 20 amps.
You should never try to use more than 15 amps through a 14 gauge wire.
You would need to know the maximum watts and voltage you could generate then go from there. In home use you use 12 gauge wire at 120 volts to handle up to 20 amps. 14 gauge for 15 amps. If you're operating in 12 volt it's a different ballgame.
12
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.
12 guage wire israted for 20 amps and 10 guage is rated for thirty amps! 12 gauge is what is required, as it is rated for 20 amps. 10 gauge is rated for 30 and will be more then enough. Oversizing wire in your case isn't necessary. The thicker 10 gauge wire is harder to work with and will more then likely cost more.
The guage of wire for 20 amps is #12 copper.
12 amps is 80% of a 15 amp circuit which is the maximum that should be run. Other factors such as wire size and length also play a part in calculating a safe maximum Jeff
In normal residential use it is 20 Amps. That depends on alot of things such as the wire insulation, ambient temperature, etc. Standard NM 12/2 (Romex or equivalent, which is likely what you are asking as it is the primary type used to wire residential) is rated for 20 amps, 14 gauge is 15 amps, 10 gauge is 30 amps.
