From 320.40 AC Cable "in addition, an insulating bushing or its equivalent protection shall be provided between the conductors and the armor."
Is not in the Article for MC Cable
Explain to me why it's not in both Articles

I stand corrected, it seems they are not required by code. I will still use them on fittings that do not have a insulated throat. I have had stuff blown up in my hands cause they were not used. But that could have had been caused by the knucklehead that installed it breaking it in half and using dikes to strip the armor, instead of using the proper tool.

I'm not trying to get into a argument here, all I'm saying it is common practice here to use them when they are required by the fitting style. I personally try to use fittings where they are not required. I know some of the bushings have a little tail on them that protrudes passed the fitting into the box, I was told a long time ago this was for the inspector to verify that it was installed. I'm sure they told you that, and its probably true. I have just always installed them, and probably always will. Call me old school. Im sure they cost next to nothing to produce, but why would they attach a bag to the roll of MC. Personally, it gives me peace of mind that there installed when the fittings require them.

This topic was hotly debated on one of my electrician groups on Facebook

Someone actually called the manufacturers to ask this exact question.

The answer?

Theyre NOT required(wasnt part of the testing for the listing) and they only include them to cut down on all the calls they were getting when they werent included with every roll.

They are most definitely NOT required.

Maybe it would be good for you to real the listing with the NRTL. That will clear it up for you.

Its not the inspectors making the call, its the local authority. we are not a state wide license. when I was licensed 17 years ago, there was only 4 states that were not state wide. I'm sure your state wide. Every municipality here has there own electrical board, who determines what code cycle they are in, and what parts they are going to adopt for it. Some of the smaller municipality's will just follow bigger municipality's rules. So each one has there own inspectors following there local rules. It has nothing to do with getting a inspector in trouble. Just because a new code cycle comes out, doesn't mean the we have to start applying it. Its has to be adopted by each municipality. so depending where you are working here, you have to know what code there in. It is crazy at times. I currently keep about 4 licenses active each year, yes most larger municipalities have their own license here. we are working on a state wide license, where St. Louis county would be the standard for the whole state. So I hope you understand more what I mean. Its not the inspectors being able to change the code at there will, its the municipality they are employed with. I know someone that works for a contractor across the river in Illinois, they are also not state wide license. When they wire new homes, they will bore 2 inch holes through the basement joist for all their home runs, they put them all in one big hole. If we tried something like that here, they would look at us like we had three heads. Only one romex per hole

Ok so your AHJs dont know what theyre doing then.

If it works just fine and does not cause a fire or other issues such as structural integrity, then your AHJs need to educate themselves....but ignorance is bliss i guess

Thats exactly why it happened. But why are you working things hot while they are in your hand?

In another thread you said you'd been an EC for 20 years ;)
Which one is it?

don't really know why of if I said that. Could have been exaggerating I guess. I have been licensed by St. Louis City since 2002, and St. Louis county since 2003. And also St. Charles county and Jefferson county. Any thing else you would like to know. Why is it some people on here just try to find something wrong in what you post.

Why cant you just understand that things are practiced differently across the country. I have to know what the inspector wants to see when the get here. I don't make the rules, I have to follow them, as crazy as they may seem. Do you really think I would Tell a AHJ that they don't know what they are doing. They would make it hard on me from every job after that. That's the political part of having a license here, rule one, don't piss any body off. I have a good relationship with my inspectors and AHJs. If I would move to you're area, I would have to adapt to the way it is done there, and the same if you would move to mine. I am done arguing. I stand corrected about the anti short bushings. Its the way I was taught in school, its the way we did it when I worked for a contractor and its still the way I've been doing it as a contractor. never really gave it much other thought.

It's not a GOTCHA ;)
It's a necessary evil, all about credibility. Some of us here have been around Electrical Forums for more than 20 years. We pretty much are quick to call BS when we see it. If allowed to stand, some serious consequences could result. :shocking:

Some electrical forums are not only Nationwide, but Worldwide. This is the internet for Pete's Sake

These are listed for AC to 1/2" EMT. They do need to be accessible.

In New York we use the “ from too’s” all the time. I have also used rigid couplings to m.c connectors with the appropriate r.e. A lot more expensive way to go about it however. Doing it on a school job right now, inspector is fine with it.
