That is?
What's with the comments having to be 10 characters?

I've run into a lot of electricians, and contractors, and supply houses that have absolutely no idea what those MC connectors are... so here's a link. I get a chuckle out of the ones "Provided with insulated throat and tinted red inside." Any ones better out there? Not IMO.WastefulMiser said:What's an "Antishort for Greenfield"?
The MC connector I refer to is the snap-on type with three prongs inside. Are there different [better?] ones out there?
Romex connectors, eh?

Bill W said:The anti-short bushing is crucial to a safe mc installation. IWIRE says,
"Redheads are not required to be used on MC by the NEC."
Those redheads come with the mc and are covered by the code insofar as following the manufacturers instructions.
I was prepared to stand corrected, but this is not a cut sheet for mc cable, nor is it an article of code. It is only NEMA attempting to make an interpretation of existing code, giving no consideration to the manufactuerer's intention, and trying to tell local authorities how they should read the code.iwire said:No, you are mistaken they are not required by the manufacturer.
You obviously did not follow the link I provided from NEMA. (National Electrical Manufacturers Association)
Here it is again NEMA Bulletin 90
If you take the time to read the one page that link brings you to you will find that both NEMA and the NFPA say the use of red heads with MC is OPTIONAL

NFPA Code Making Panel said:[FONT=TimesNewRoman,Italic]Anti-short bushings are not required for Type MC cable in accordance with the listing for the product. The termination fittings approved for use with Type MC cables are designed such that the wires will not come in contact with the cut edge of the armor; the throat of the fitting is small enough to prevent contact with the armor. Type MC termination fittings perform the same function for Type MC cable as Type AC terminations plus the anti-short bushing do for Type AC cable. [[/FONT]/quote]

Short of getting an official NFPA interpretation that is as official as it gets.
Your claim is that the red head are required by manufactures instruction but the manufactures association says no that is not true.
The NFPA has refused to add a code section requiring redheads with MC cable.
So I say again clearly and plainly Anti shorts are not required by either the NEC or the MC manufactures.
I do use them by choice not by any code.
Of course a local area might make an amendment requiring the use of them but that is a local matter not a national one.
Bill W said:I see NECA (national electrical contractors association) and NESI (national electrical standards institute) have published an entire volume on the installation and accessories necessary for safe and workman-like practices when using mc.
I have worked in this trade many years, mostly in commercial and industrial installations, and I have worked w/ over a hundred other electricians. I have not met one who didn't use redheads when putting connectors on mc.
If I had, I would have told everyone, and such a shoddy practice would have quickly been addressed.
NFPA70 is a minimum standard, and does not necessarily address workman-like practices, only requires that they be used.
Bill W said:stop it! or i'll post a thread that says iwire doesn't like redheads...only blondes, and brunettes.
Bill W said:There is no implication here that I am talking about redheads. Clearly, workman-like practices are the focus of the above, quoted sentence.
I would like that. I'm not familiar with the style manual.iwire said:Well I did not find it clear or accurate.
You want me to post the section of the style manual that lists the words Neat and Workmanlike (along with many more) as vague and unenforceable?
