tap rules in bathrooms.

Note that the wires are described as running from the luminaire to an outlet box, not from a luminaire through an outlet box and raceway to a switch box.

Q. What is the smallest size wire you can use for a lighting fixture whip?
A. Fixture wires as small as 18 AWG are allowed to run from the luminaire to an outlet box, as long as the conductors are not more than 6 feet long [410.117(C)], and they are connected to a circuit rated not more than 20A [240.5(B)(2)].

Note that 410.117(C) is a special provision applying only to Flush and Recessed Luminaires. It is not a general rule.

Are you saying that 410.117 does not say that there is a six ft. tap limitation to recessed and flush mounted fixtures.
...

I guess I am saying that CMP18 does not have the authority to write an overcurrent protection rule. That authority rests with CMP10.

With much respect Don , I am not sure how the user of the NEC can determine which sections can be ignored because a particular rule is written by a Code Panel that did not have the authority to address the subject.

I guess we are assuming that the six ft. limitation for flush and recessed fixtures was for overcurrent because nothing else would make any sense to limit the fixture tap length.

How do we determine the panel responsible for the rule does not have the authority to emblement the rule that made its way into the book?

This is something that should have been caught by the correlating committee.

The rule does stand until challenged, but unless there is a technical reason for the rule it should be removed from the code, and if there is a technical reason for 410.117, then 240.5(B)(2) needs to be removed from the code. These sections are in conflict.

410.117 is not a rule that I would ever enforce if I was the inspector, assuming that the fixture wires are protected per 240.5(B)(2).

Very key point made -- The fixture whip is terminated in the fixture and is not considered an outlet by definition IMO and is attached to the switch leg at the outlet j box -- A wall or ceiling mount fixture has the fixture wires that terminated in an outlet.
