Be very careful you pay very, very, very close attention to what the superscript 1 next to #14, 12, and 10 stands for. It's real important. Electrical code is really nothing that one should learn via internet, although I understand where you are coming from with this. 310.16 is fine and good, but if one doesn't know the correct way to interpret it, including the impact of terminal device ratings, unguided and uneducated use could be a recipe for problems.

This is the most relevant part of that

1 The load current rating and the overcurrent protection for conductor types shall not exceed 15 amperes for 14 AWG, 20 amperes for 12 AWG, and 30 amperes for 10 AWG aluminum and copper-clad aluminum after any correction factors for ambient temperature and number of conductors have been applied.

Also to the novice this info can be misconstrued if they are not familiar with wire types and the type they are using.

For most instances the insulation type will be THHN or THWN (suitable for wet locations) but Exception 1 supersedes what is written in 310.16.

Any good info is worth posting. Its up to you to understand what it means.

310.16 really just tells you ampacity for wire gauge. However continuous loads over 3 hours in duration need to be multiplied by 1.25. Also voltage drop needs to accounted for. Then you check 250.66....
