C-H
The one in the picture that sven posted looks exactly like the ones I use, they will fit up to #12 awg, when I do FA work it is mostly #14 awg, 2 #14s would not fit in the hole and would be a violation of the listing. I also have ones that hold up to #8 awg
The ones I get come in strips of 12 pairs (24 holes) I would call the one in the picture 3 terminals (6 holes) only 6 wires total could be landed and only 3 of the 6 are electrically connected You break off
the number you need.
When you need jumpers they are a flat piece of metal shaped kinda like a comb, you break or cut off the number of jumpers you need these will fit in the terminals along with the conducter.
Doing Fire alarm work jumpers are not needed as we do not "T" tap anything.
