When it comes to electrical wire gauge the lower the number the thicker the wire. The thicker the wire the more current it can carry. This is why 12 gauge wire is often used in applications that require a lot of current such as in an RV or a large home.

12 gauge wire is rated for 20 amps. This is the maximum safe current that it can carry without overheating. If you try to draw more than 20 amps from a 12 gauge wire it will start to heat up and could potentially catch fire.

It is important to note that the rating of a wire is not a guarantee. It is simply the maximum safe current that the wire can carry. If you are using 12 gauge wire in an application that requires less than 20 amps it is not going to hurt anything. The wire will simply be capable of carrying more current than is necessary.

In general it is always better to err on the side of caution. If you are not sure how much current your application will require it is better to choose a wire with a higher rating. This way you will never have to worry about the wire overheating and causing a fire.
