So, I'm aware of 14-100 with tap conductors, I just was learning about it in school, but I'm not certain about this one particular application.

In this installation, the boss has a 20 amp circuit w/ 12 gauge wire feeding the first device, but then a 14 gauge wire goes from that outlet to the next device (which will maybe pull 1 amp tops). I am just trying to figure out what code applies to this installation. The inspector allowed it on the last building so I'm assuming it's permitted somewhere in this massive CEC book? It does make sense given Kirchoff's Current Law that the full 20 amps will never go through that 14 gauge wire, just curious. Is this 14-100, or some other rule I'm not or less familiar with?
