Would you consider Ty Wire an acceptable means of supporting and securing MC Cable?

I would say yes, but it is up to the AHJ to "approve" the securing and supporting means.
Take a look at 330.30(A).

IMO tie-wire is stronger than tie-wraps and they're permitted. However since tie-wire isn't specifically mentioned in Article 330 it's as Chris said, up to the AHJ. Maybe this would be a good proposal. :smile:
Maybe.....it's pretty much SOP to use tie-wire on MC here .

Yup. It would be nice to have it included in the code wording to eliminate having to ask for approval when using it.

An old shoestring would work well too 
Heck, if Romex scraps can be used to secure Romex, what about MC scraps twisted up to secure MC? :grin:

If you can get the AHJ to buy off on it more power to you.

Ok by me
Ok by me
I've used tie wire many times, have occasionally seen an inspector that didn't like it. I try to keep it neat looking, especially in open sight. Much easier than bang on caddy clamps w/spring clips, I hate those. I sometimes use tie wire as a messenger cable as well, across a chasm or from a high bar joist down to a light, if needed for some reason. Double up, anchor at both ends and tie wire the MC to it every 2 or 3 feet. I use ceiling hanger wire for that if I have it.
