NM verses MC

[mkgrady]

My understanding is that NM cable ampacity is limited to the 60 degree rating. Is that also the case with MC cable?

MC does not have the 60? restriction given NM cable.
Terminations must still comply with 110.14, so the 60? might apply in some cases.
The actual conductor ampacity is determined by the conductor listed in 310.13(A).
(Southwire uses THHN/THWN I believe)
