Combining two NM-b wires through one single connector
The KO holes on top of my electric panel is getting almost used up.
Most of what I have are EMTs, but I do have six NM-b wires that use up six 1/2" KO holes.
Is there a way I can combine two 12-2 NM-b wires to share a single 1/2" KO hole? If this is possible I would immediately free up three unused KO holes.
I have seen some double barrel or duplex metal clamp connectors for two wires such as these.
Can I use these to share one KO hole between two NM-b wires?

Yes..... those connectors are designed for two cables..... NM-b included.
Many standard NM-b connectors can also be used with multiple cables.
