Max. wires through "romex" connector

What’s the maximum amount of wires through a large romex connector/restraint/clamp (or whatever you know them by;-))
And no I don’t no the UL listing info.

thx in advance.

The connector needs to be listed for the size and number of NM cables used. That one in the photo isn’t so listed.

Based on what you have shown…(1) Cable only unless expressed otherwise with it’s listing as Robert stated.
