I need to run two new 20A circuits to the other side of the house - at Home
Depot I see this "12-2-2" romex cable with 2 hots, 2 neutrals, and one
ground. Is it safe to share that one 12ga. ground between two 20A
circuits? (I "assume" it was a 12 ga ground, it's up in the air on the
spools at HD so hard to get a close look)

IMHO:

Since the ECG only carries current for a very short time, in a ground
fault, you should have no problems sharing the ground. I've run emt
with many circuits and a single ground wire. So, imho, I don't know
of any problems with the code against doing this.

BTW, now if you are interestinged in running two circuts in the same
cable, why have you ruled out 12/3 ?



Does 12/4 armored cable (MC or BX) only have one grounding conductor? or is
it better because the metal jacket is an additional/supplemental grounding
path?

Personally, I like having a seperate ground, so this rules out AC as
my choice. Plus, as for the MC jacket, it can only be used as a
ground if listed as such. Eventhought it is grounded.

From your questions, you are doing the right thing planning out the
project before you runn around buying stuff.

Might want to post what you doing(or intend on doing) to get
suggestions how to do it best.
