armored cable connectors

[TwinCitySparky]

Trying to confirm that the "snap-in" style connectors without a screw cannot be used with AC cable - only MC.

I've looked at art 320 - AC cable absolutely needs a compression style connector. Is this true? Thanks

There are a gazillion connector types out there today. I would be surprised if there is not a snap-in connector for AC cable. The best way to find out is to open a manufacturers's catalog and look for the listing.

Depending on the area, and what code cycle you're under, a sanp in is not permitted.

I agree with Pierre. The manufacturer's listing of the connector would be needed to provide that information. Here's one such connector that so listed:

Wow - they do make them!

I figured with the internal bonding strip design of AC cable that these types of connectors would not be acceptable.

I'll make sure the type I use is indeed listed for AC.

Now I know!

Thank you!

We have a job where our installer used Southwire HCF MC-AP with Arlington 38AST fittings. He had looked at the box and determined this was an acceptable fitting. But the label on the MC says "Use type MC cable fittings marked MCI-A." I did not see this on the box. Are these fittings still acceptable?

After a long week, and sitting, typing and eating snacks, I am too lazy to look...isn't the designation I highlighted for box clamps???

I use those arlignton connectors they are quick. I still think they are hard to remove.
Install is a time saver.

Bridgeport makes fittings that snap in and are easier to remove.

I had an easy week of working on roofs and in attics so I'll look. Oh here it is, Southwire is only to be used with T&B connectors???

Also MCI-A listed. A search of Arlingtons site shows no results.

Oops, not an acceptable fitting. Here is the list of fittings from Southwire. (pdf)

"marked MCI-A"

Take a look at (QCIT), Metallic Outlet Boxes
UL White book.

Those designations are also used for box clamps. Page 258 of the '08 version.

""MCI" for metal-clad interlocking armored cable"

""MCI-A" for metal-clad interlocking armor ground cable"

Attics - for sleeping where no one finds you...
roofs - for watching the scenary walking by...

...I can see why you call that an easy week.

Florida in September? Thats the kind of sleep where you never wake up.

The cable manufacturer's table is a great starting point, but the manufacturer label is the most up-to-date indication of what the fitting in the box can be used on.
