Combining two NM-b wires through one single connector

753 Views 2 Replies 3 Participants Last post by  Arrow3030
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?

You can put two 2-wire NM cables in a typical two-screw NM connector.
