New MCAP and HCFMC

[tkb]

Look in Electrical Contractor magazine, Sept 2005, page 147, top center.

Southwire has released their new MC and Health Care Facility MC that uses the jacket as a grounding path.

Instead of a green wire it has a #10 aluminum bare conductor between the mylar and the armor.

To terminate you would just cut off the aluminum ground wire.

I called Southwire and they said they are now shipping this product.

Last year I saw something on one of these sites about this new cable. It was called "MC Smart" or something like that.

South wire emailed me a couple of PDF cut sheets on these cables.

I don't know how to post them, but if anyone is interested and would like to post them I could forward them to you.

I don't know if this would be a "ground wire", but a bond wire similar to AC cable. It serves no other purpose than to reduce the inductive reactance of the jacket. So how would this new cable be any different than AC cable?

I think it must still have an insulated grounding conductor along with the 10 bare in order to provide redundant grounding for patient care areas.

Yes on the HCFMC it has a green wire along with the jacket.

I described only the MC not the HCFMC.

Re: New MCAP and HCFMC

That makes sense.

I am not sure I understand what the new MC will be used for.

You know the jobs we work on often call for a copper EGC in each raceway, I doubt many engineers will back away from that just so we can use the new MC.

The people that do design build will benefit from this the most I would say.

It is NEC compliant and UL listed.

The only deciding factor in picking this new HCFMC over HCFC will be the price difference between the two.
