Question:
Re: CQD answer published Thursday, March 29, 2018 -Cooking appliance Tap Conductors
1) Good morning, If I understand 210.19(A)(3) Exc. No. 1 correctly, your answer did not specify the conductors referenced in the exception are those supplied with the appliance and not field-installed branch circuit conductors such as 12/2 NM-B cable. I believe the last sentence of the exception indicates this intent. Maybe this is a place where we could clarify the language a bit? Yeah, I know, you look forward to my Public Input! Thanks for your service. J Grant Hammett
2) I agree with the answer given for the tap conductors supplying the microwave from the range branch circuit. In addition, the tap conductors would have to be hard-wired to the microwave, otherwise 210.21(B)(3) would apply if installing a receptacle outlet. The receptacle would need to be rated for the branch circuit overcurrent protection per Table 210.21(B)(3). Tom Sieracki

Answer:
Hey J Grant and Tom thanks for your comments.
1) The last sentence of 210.19(A)(3) Exception 1 limits the tap length to that needed for servicing the appliance such as if it needs to be removed from a cabinet while still being connected to the wiring method. The second to the last sentence includes appliance leads as part of the tap but does not prohibit field installed tap conductors.
2) Tom, you are correct receptacles would need to be protected as stated in 210.21(B) so a 15 or 20 ampere receptacle would not be allowed.
