What is the point of Redheads?

[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]

"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"

Right now I'm coughing and referring to male cattle excrement at the same time.

Noone question that the plastic protects the wire from the steel fitting edge but the fitting edge is stamped and rounded. How about the steel jacket with the freshly cut sharp edge ?

Does anyone actually think that the red plastic part of the connector actually slides between the wires and the steel jacket even 25% of the time ?

Do we really have that many cheap electricians that this few seconds is important ? Perhaps we need a pole

Why would you think that? Sounds like an urban legend to me. If it's my money can't I do whatever I want with it? I can give it to someone else (spending it) or I can melt it down, after all it's mine. The government hasn't lent it to me.

Defacement of Currency

Defacement of currency is a violation of Title 18, Section 333 of the United States Code. Under this provision, currency defacement is generally defined as follows: Whoever mutilates, cuts, disfigures, perforates, unites or cements together, or does any other thing to any bank bill, draft, note, or other evidence of debt issued by any national banking association, Federal Reserve Bank, or Federal Reserve System, with intent to render such item(s) unfit to be reissued, shall be fined not more than $100 or imprisoned not more than six months, or both.

Defacement of currency in such a way that it is made unfit for circulation comes under the jurisdiction of the United States Secret Service. Their mailing address is:

Everyone must use them now after an inspector failed the inspection for not using them.

He got on his knees with a flashlight and checked every box for the little red tip sticking out. Unbelievable.

They may not be an NEC requirement, but are they a local requirement ?
If they are, sounds to me that the inspector was doing his job.

Today I took a look at 'Southwires' aluminum metal clad cable,12-2,90 deg.,

dry,thhn/thwn,listed for fire wall penetration.

I flipped the info sheet over,it said "CAUTION not to be used with set screw

type connector"

It brought up the question, just what is a set screw type connector?

1) the older style two screw connector.

2) the connector inside a mc box.

3) the insulated newer style with just one screw

For me it was the first time I ever saw a warning over the use of the

different type of mc connectors.

I take that to mean the connector that resembles an EMT connector except that the screw is angled. Any connector with two screws is a clamping type.

Here is a set screw connector.

It's a connector where the screw actually presses into the armor.

To add one thing:

If it has a single set screw but also has a "foot" attached to the inside tip of the set screw so that the cable is held by the foot and not by the tip of the screw, then it's a clamp connector and not a set screw connector

I agree. This would be called by some manufacturers a saddle connector. They would comply with an aluminum cable that requires non-setscrew connectors as mentioned in Benarounds post. Here is one by Halex:
