1)shall have an ampacity of not less than 20 and
2)shall be sufficient for the load to be served.
3)The taps shall not be longer than necessary for servicing the appliance.
The above is right from the NEC itself.
Now if we go to the NEC handbook they show four items.
It is worth noting that it is not an enforceable document, but still an excellent resource.
(1)The taps are not longer than necessary to service or permit access to the junction box.
(2)The taps to each unit are properly spliced.
(3)The junction box is adjacent to each unit.
(4)The taps are of sufficient size for the load to be served.
Number 2 is not a direct part of 210.19(A)(3) but of coarse applies to any splice. 110.14
|where is the tricky part?
I think most people would be concerned with conductors smaller than 8 AWG protected by a 50 amp breaker.
