90 degree connectors

[JJWalecka]

I have heard that 90 degree connectors are not listed for concealed work. In other words, if removal of building finish is required to access a 90 degree connector it could not be used. Does anyone have facts to agree or disagree with this statement?

90 degree FMC connectors cannot be concealed. 348.42

90 degree AC and MC cable connectors can certainly be concealed.

That is not so for all applications, Check out 356.42.- 350.42.
You will not see that in 320, 330, 334

The reason is manufactured cable assemblies (AC, MC) vs. a raceway (FMC, LFNC, etc.) Can you imagine trying to repull thru an angled connector concealed in building finish?.....ie. Not accessible.

Thank you for your time.
If it is my call I will choose not to use 90 degree MC connectors in concealed work.

Which very often is the same connector, used with different wiring methods.

Why? You would never have to pull conductors out of or into a cable assembly.

If at all possible I would try to use a straight connector. Just personal preference.

That's being a little bit short sighted. 90 degree connectors are right handy in a few cases. When fishing MC cable down to an existing box, putting an MC connector on the end to come in a knockout in the back or side of a box is sometimes what you have to do. Also, for appearance's sake (and maybe even to keep the cable from "snapping"), 90 degree connectors are the thing to use to keep exposed cable laying nice. Coming out of a water heater, for instance.

Well said Marc and agreed.

I think he misunderstood my post as far as the intent cable assembly vs. raceway????

Yes, I figured that was self evident.

Do you ever use MC Tuff? They've pretty much solved the snapping problem with that product.

So you're saying this stuff is actually MC cable, but it's tuff?

So I take it you're a regular user of it then.

To answer your question, it's tuff stuff, and that's not a bluff.

I hope you guys are not using 90 MC connectors with boxes and MC. I don't think the connectors are listed to connect to anything. :wink:

Silly me. I always connect them to boxes with 1/2" knockouts. Now I have to search for special MC boxes.

I have bad news for you. They don't make them.
