Not in the areas that require redundant grounding. Also remember that FMC over 6’ is not permitted. You really only have 2 options, a metal raceway (RMC, IMC or EMT) with separate insulated ground wire or HCF AC cable.

thanks, you can always rely on good information from the members of this site..recently was hired to help a contractor out of trouble with a couple jobs..i thought ent and bx looked funny for some reason and ENT WAS longer than 6 feet to boot!

80% of 6000 sq foot of building was ready for rough-in..told boss that there was problem...he decided to fire me...i decided to call the state and ask them who was right..

boss should have taken two and thought it through..

inspectors shut em down for using bx and ent

not a license on the job even though required..

i resigned way before he decided to fire me for questioning his knowledge!

i wonder what he will do now? i am surprised he did not do it in romex!

the cost of that job just doubled...

sad situation these days..

Zapped,
I could read Article 362 a thousand times but ENT will not meet the redundant grounding requirements of Article 517.

You can't concentrate too much on "redundant ground". That could just be two green wires.
The fact is 517 says one of these grounds will be the "metal" wiring method itself.

517.13 Grounding of Receptacles and Fixed Electric Equipment in Patient Care Areas.
Wiring in patient care areas shall comply with 517.13(A) and (B).
(A) Wiring Methods. All branch circuits serving patient care areas shall be provided with a ground path for fault current by installation in a metal raceway system, or a cable armor or sheath assembly. The metal raceway system, or cable armor, or sheath assembly, shall itself qualify as an equipment grounding return path in accordance with 250.118. Type AC, Type MC, Type MI cables shall have an outer metal armor or sheath that is identified as an acceptable grounding return path.
(B) Insulated Equipment Grounding Conductor...

Sort of eliminates any plastic wiring method huh?

Trekkie, yes it is allowed in "Non Patient Care Areas" specifically per 517-12, which would also allow NM or any other wiring method in chapter 3.

Out of curiosity, is your area still under an NEC cycle pre 2002?
