I'm curious if it's to code to use one wire (with 1/4" spots that have the sheathing trimmed off, which connect to the terminals) for all my grounds and one wire for all my hot connections in a multi-gang switch box. This is an attempt to reduce the pigtails in the box.
Is there a term for this idea/technique? I thought it might be called daisy chaining, but I don't know if that term is specific to this technique.
Below is a pic of what I was doing prior. I'm also curious if the wire nuts aren't big enough for all 4 of the wires, if I can safely use a wire to jump to another wire nut (reducing the wire nuts to only 3 wires each)?
