Someone once told me: Don't speak of it ... if it's good it runs away, if it's bad it shows up!
I just encountered a remodeling job - the guy wants to add a third switch to several 3-way light circuits. My first thought was to simply interrupt the travelers, then run a single 14-2-2 from that new j-box to the new new switch location (re-tagging the neutrals).
Well, under the 'run a neutral' rule, that short-cut is out; looks like I'll be running some more wire. Oh, Well!
Edit to add ... Since each room (for this project) has two levels of lighting, that means there will be two 4-ways at each location. Adding the neutrals and grounds means I need room in the box for 16 wires (plus pigtails, etc.) Let's face it; "switch" boxes and "stack" switches are now restricted as to your use of them.
Just run a single neutral and ground? If I was coming from a single j-box in pipe, I could do it. Since I'm using Romex, that's out - there's no form of Romex with 4 'hots,' 1 'neutral,' and 1 'ground.'
The "Law of unintended consequences" just kicked in.
