Thoughts on rough in

Recently some coworkers got into an argument over a rough in, one of them wasn't removing the plastic wrap around the mc cable and left it sticking out of the back side of the connector. I'm not sure either one had a valid argument but I'm just wondering if this is 'acceptable', I could see arguing 110.12 but does it really apply here when it's going to be above a ceiling or encased into a wall. I suppose it doesn't really make the rough in look too bad and it would create less mess and save some plactic from going into a landfill since we all know it's not going to be recycled.

Just wondering on your thoughts

Even though the jacket isn't listed as an EGC it is still required to be bonded. IMO the wrap cannot be between the connector and the jacket for this reason.
 
It does look tacky. I can see it partially interfering with the bonding of the jacket. I suppose that could be a valid argument for a code violation

The bond is where the set screw is, IMO. It is sloppy looking, but I don't think it fails on that point unless the plastic is between the set screw and the armor.
 
I have seen it wrapped around wires to "function" as a RedHead/bushing, never just left that way. That is beyond lazy- you don't even need a knife...
 
See if you can get them arguing about it again and video tape it. :DThen post it here. (y) We could all use a good laugh.

Oh how I remember the times when I could argue about something so insignificant. I only wish life was that easy now.
 
If it's not going to be inspected anyway.

In California 95% of the residential work is never inspected.

Plus, they use "Combination" inspectors who are clueless.

Take a closer look at that connector. There isn't a "set screw" it's a single screw which tightens the clamp plate. Obviously it depends on the position of the plastic whether it is in between the mating surfaces on each sid.

And I doubt that when the connector was tested as part of the listing of the connector that they had the wrap between the metal surfaces. For that reason I say violation.
 
I know red heads aren't required, but I just put them in anyway. I leave the plastic on until I get the red head in as it makes it go in better/faster, then I cut the plastic off. I would never leave that ugly mess hanging out the connectors! Even if I didn't use the red heads I still would cut the plastic off before putting the cable in the connector.
 
Looks like something a first year apprentice would do out of ignorance and then get teased throughout the rest of the job for.

Redheads are required fyi nec says to follow manufacturer installation instructions. If the instructions say to use the. They are required
