Iwire...I haven't seen it in the supply house yet.I have seen samples of #12 MC and also #12 HCF MC.

The metalic sheath was wrapped tight. The aluminum bond was #10 and was not covered with the mylar wrap.

gfretwell...dry location only with THHN rated conductors only.

I too would fear loose connecters at juction points leading to high impedance grounding with its use.
