Two Romex cables through one connector?

Is it legal to secure two Romex cables through one connector?
Can Romex be stapled on top of another?
Thanks
Bill

If the connector is listed for multiple cables it will state the sizes and number on the packaging.

If the staple is listed for multiple cables, see above, you can staple 2 flat cables flat to the stud. The cables cannot be stapled on edge.

Depends on connector size and romex size. I have seen 2 pair of 12/2 romex coming in through one connector (can't recall if it was 1/2" or not). And yes you can staple multiple pairs under one staple. Make sure you have the correct length staple and don't overdrive it, no one is going to be yanking on them

No, as pcboss stated, it depends on the U.L. listing. What we typically think of as a 3/8" romex connector that fits in a 7/8 Dia hole (1/2" K.O.) is generally not listed for more than ONE NM cable. There are however, duplex connectors that are U.L. listed to accept TWO NM cables and these connectors also fit one 1/2" K.O. As far as the staples, regardless of length, I haven't seen a cable staple that was U.L. listed for more than ONE NM cable, but I am not saying there aren't some out there. I'd be interested in seeing one that is listed for more than one cable.

By the way, 2 pair of 12-2 romex cables would be 4 romex cables.

Halex this is a 3/8 connector rate for 2 cables

When I said two pair, I didn't mean 4 cables, only 2 complete 12/2 cables.

I will have to go check what I was looking at today. It had multiple 12/2 romex running through it. The knockouts were no bigger than 1/2", but I'm pretty sure I saw a few 2x cables run through some clamp style connectors.

CJ, peruse this link. Check the SN 150 listing.

Briscon Products - STAPLES

In my experience most NM connectors are good for 2 flat 14-2 or 12-2 NM cables. Only one round cable per connector. Again the package needs to be checked.

Well, I guess I have to stand corrected. It just goes to show you how things change every day.

I suppose we all can learn something new every day. I think I'll pass this info along to a few friends who do residential work.

No need, you spoke from your experience as did I. Our experiences are different, not wrong. You are speaking to UL safety ratings, which is true. I was speaking from what I have seen done, not UL approved, but not necessarily unsafe either.

Well, I have seen it too, but many years ago and I really don't think back then it was technically U.L. approved, but inspectors accepted it. Over the years I think the quality and education of inspectors has increased tremendously in most areas just like materials and approvals have also changed, it's actually not an easy thing to keep up with. Today you better know your codes and materials or you won't make it through a tough inspection.

True, true, mostly for insurance reasons. Manufacturers not wanting to pay out in case of an accident, or insurance companies not wanting to payout if they can prove a non-UL occurrence linked with the loss. I can't imagine how many homes and business around the US have code violations and non-UL approved methods/products in them w/o incident. Not saying its correct nor should we lower our standards just that its commonplace.
