this is a question about the use of mc cable in health care facilities.when can you use regular mc cable vs.hcf type, especially as it relates to nursing home applications?i know that nec 517 and nfpa 99 apply to this situation,however as it pertains to nursing homes it seems to depend on the classification of the nursing home function.

Re: mc cable application?
the use of MC cable can apply if the sheath is a listed grounding conductor, check out 517.13(B) for grounding of receptacles and fixed equipment in patient care areas. Applies to nursing home, not limited care facility

Re: mc cable application?
The interlocking armor type of sheath on MC cable is not listed for use as an equipment grounding conductor. There is no such thing as health care facilities MC cable. That cable is AC and not MC.

Re: mc cable application?
The only products I found on that link were HCF AC. I did not find any HCF MC.
Can you provide a more direct link? Thanks!

Re: mc cable application?
You can talk with AFC's people. NEC 517.13(B) required the extra ground for "patient care." Patient care is defined in 517.2 and lists General care areas where patients come in contact with various items. If the nursing facility is assisted living with apartment style units and common dining, etc; MC is probably O.K. If medical assistance is provided in the unit, suggest using the extra ground.

Re: mc cable application?
Jhines, the issue is redundant grounding per 517.13(A) and (B)
There is no corrugated MC that would comply.
The ground strip in AC (517.13(A)) and HFC (A)and (B) accommodates this requirement.
If someone were to shop hard and found smooth MC it would also meet the requirement.
If the area is not under the 99 code, no flexible conduit or cable (excluding MI but you will probably have train everybody to use it) can be used for critical or life safety branches.

I agree with Tonyi even though MC IG has two copper grounding conductors it still does not meet the requirements of 517.13(A)

The use of the term bonding conductor(s) seems even more appropriate in health care facilities although IMO it is better for all uses.Don is smiling somewhere right now
