Romex connectors on service panel

[dm9289]

I was looking thru last months posts and a service panel was shown with attachment violations on several nm cables ( no staples). But it also had appeared to have multiple NM cables sharing metal nm clamps entering the panel. Is it a code violation to put more than one NM cable under a metal clamp and if so could you point me toward the code reference?

Thanks
Dave

Look at the box of the romex connector. The listing and labeling of the item should be listed there.

A typical romex connector might look like this:

If you check the manufacturer's list, you will find that this particular connector has multiple listings for cable combinations. It is cat #841, and second on the list:

The Code section you seek is 110.3(B).

KBSparky,
Can you post a link to this information? Thanks.

http://www.arlcatalog.com is the homepage.
click on "NM Cable Fittings and Supports"
then 3rd one down "NM Cable Connector"

if you right click a picture and select Properties, it will show you the web address of the picture. you can then mostly shorten that link to get to a homepage.

Not all of them are. The sad thing is this info ;no of cables permitted is not usually on the connector box. Catalog listing only.
