sizing of conductors for motors

[mooreaaryan]

Does 240.4 (max ocpd on a 14awg is 15) apply to the sizing of motor conductors. If not is it specifically stated or is it just "understood as"

Short answer is no. If your equipment has 75° C terminals you can use the 75° C ampacity of #14 which is 20 amps. If it's NM cable then your stuck with the 60° C ampacity of 15 amps. MC cable or pipe and wire then 20 amps is permitted.

The clue is in the wording
240.4
..........................................unless otherwise permitted or required in 240.4(A) through (G).

(G) Overcurrent Protection for Specific Conductor Applica tions. Overcurrent protection for the specific conductors shall be permitted to be provided as referenced in Table 240.4(G).

Hopefully moderators are paid...if not they need to add a tip button...a lot of thinking alone pushes you into a downward spiral of what ifs and how abouts...your clarify and guidance is superb (tip button here) thank you so much
