I think if you backtrack to 210.19(A)(3) Exc. 1, or 210.19(A)(4) Exc. 1a and 1b, you'll find an answer.

In Table 210-24 what is the meaning of the word Taps?

Tap Conductors. As used in this article (Article 240, not Article 210), a tap conductor is defined as a conductor, other than a service conductor, that has overcurrent protection ahead of its point of supply that exceeds the value permitted for similar conductors that are protected as described elsewhere in 240.4.
​
The definition is not referred to in 210-24, which is just a summery, but 240(E) refers back to Article 210. :smile:

i dont know if im explaining this right, but basically a tap is when you attach a wire to another wire using either a split bolt or a connector.

Basically, a tap is a connection of a smaller conductor to a larger conductor without a properly sized overcurrent protective device.
 
So on a residential 20 amp lighting circuit one could use a 14 awg for the switchleg to an individual fixture? I always thought you needed 12 awg all the way through.

Who said you can do that? When used as a "general" branch circuit, #14 is limited to a 15A max OCPD. There are no rules in article 210, 240, or 310 that modify this requirement.

I was looking at 210.19 (A) (4) ex 1a, but I guess that applies to the fixture wires.
