I swear I remember reading in the NEC that "change overs" are permitted as long as the fitting used remains accessible. I can't seem to locate this rule now in the 2008 NEC. Perhaps Iam mistaken on this matter?
 
Yes, stripping back armor and installing the conductors in a EMT sleeve. I think it makes for a better looking install for landing homeruns into a surface mounted enclosures.
Thanks Bob!
I should have found that one , Im getting a bit lazy it seems.

Your just talking about striping a lot of the armor back and push in the wires right?

Does the armour need to be stripped back any more than what is required for the box?

That might depend on the 'style' of the fitting.

Let's the style is:
Set screw connector-threaded coupling-MC connector
or
a pipe-to-flex (from to? ...etc)

How much gets stripped for either set-up?
 
Celtic, The fitting in the picture looks like it would have to be stripped all

the way, I don't think 2 mc cables could fit in the emt with the armor still on.

Don't the fittings for mc have a hole for the wires to go through and the

rest of it stops the armor from going in more ??

Some do...there is a squeeze type connector that fits [is listed for] AC, MC and NM - it does not....most duplex MC connectors do not ~ some duplex conns are rated for one wire as well.

In that case it looks like you can insert as much mc as you feel like, unless

it states otherwise, which I doubt.
 
I thought i read in ECM somewhere that you can only change over if you only use 2 fittings (2008) (the emt con, threaded cplg, mc con.) would be illegal then. Is this not the case?:-?

That would be 3 fittings :smile: ....

There is a thread on this forum somewhere that links back to the EC&M story.

thats what I posted, I thought an earlier post suggested to do that and I thought it was a violation now.

I guess that depends on whom you ask :smile:


Here is a link that to a thread here: RMC to FMC Transition
That link leads to another thread on this forum.

NOTE: Seems some of the images have disappeared ...but these are old threads.
