Can #3 be used for AC or MC cable and if not, why not?

I'm imagining it's because there's nothing to hold the anti-short bushing into place and protect the conductors from sharp edges?

#3 Is a squeeze type flexible metal conduit connector, Sven.

The inside fit #7 FMC connector is about the only one that I see used up to about 2".
Larger sizes usually have the #3 style.
I've not seen the #5 setscrew style (or the T&B "Tightbite") in common use for a long time...S

#7 is a 1/2" flex connector. Not a 1/2" greenfield connector. It is suitable for termination of liquid-tite flexible metalic conduit where the liquidtite does not terminate in a wet location.

We use these in the sign industyr all the time when we mount channel letters flush to the wall. It is listed for bonding our letters and with the application of silicone sealant around the connector and penetrations has yet to fail a challenge by any electrical inspector. Though it has been challenged several times.

It has always been on a listing for grounding or bonding issue. Which it easily passes in the 1/2" use...

According to Thomas & Betts, #7 is an "Uninsulated screw in connector for types AC & Flex".

If they've been working in LFMC, good for ya, but the catalog listing isn't for that application.

Batch, "greenfield" is a slang term for "flex" ( which is slang for Flexible Metal Conduit ).
