Unusual MC fitting

When they first came out, I thought of backstabbed recpetacles right away. I was suspicious of them for a long time. Eventually, I shorted one out with an extra truck battery for probably 20-30 seconds. I started to get sparkles between the coils of the MC armor, but the teeth of the conntctor-to the MC cable were unaffected. SOLD!

I did no such test and I was convinced almost immediately. What sold me was how tightly they gripped the cable and what a pain in the rear it was to take a cable out if you had to.

Then again, I tend to latch onto new products pretty quickly anyway. :)
 
Merry Christmas everyone ,.. I have used them on bx /ac cables in many an old victorian ,.. they work great , they have plenty of space for the beeswax covered wires ..
 
These connectors are the norm around my area.
They use them on everything including FMC which they are not list for.
From what I've heard is FMC connectors have that tight circular nose to keep the wires in the center of the connector.

I've been using the connectors lately that just have teeth inside. Just jam the cable in. No screwdriver required. Pretty slick. The upcharge nearly offsets the labor savings, and the redhead is already part of the connector.

I know, once you use these its hard to go back to the set screw and locknut type

I'm curious why you're doubting the listing. I've never seen that brand of fittings around here, but they look just like every other set screw AC cable connector on the market. And I'd also say they are just fine when used properly, which these particular electricians clearly did not.

There is a lot of counterfeit stuff on the market these days.
I have never seen a single screw fitting being used for aluminum type MC, hence my curiosity.
 
Next time you get a roll of aluminum jacket MC, look at the tag. They used to state something to the effect of "do not use set screw connectors". It's been a while and I forget which manufacturer.
 
SANDSNOW, If you can't use a set screw type connector on alum MC how do you connect alum MC into a threaded hole (like a WP box?)
I've never seen a MC connector that could be threaded into a 1/2" hole w/o a set screw. Usually with two screws, but I have used the saddle style w/ one screw. Maybe the saddle type isn't considered a set-screw connection? I'll have to look at my MC tag next time I get the chance.

I'm with you on this. There's a ribbon inside the MC that indicates this.

IMHO, rather than use connectors that might be questionable on a job where you will have the onus of proving that they are approved for use with MC, holding up the job, not getting paid, waiting for the inspector to make a decision, yadda, yadda, yadda, I would just use the appropriate connector. Why pust the envelope ?:confused:
 
Actually, I carry these fittings for use on old BX cable. The hole in the throat is nice and large for those old cloth/rubber conductors that won't fit in some other BX/MC connectors. Fortunately, all that old BX is steel.
