A few years ago it was the norm to use the EGC for the neutral for dimmers, occupancy sensors, and the like. And that prompted 404.2.C - include a neutral to switch locations.
As I recall, plenty of equipment was sold that used the EGC. I also recall calling Lutron (about 7 years ago) asking why they were selling two different kit - one that used the ECG and one that needed a neutral. The response was, "When the NEC and UL get their acts together and are on the same page, we will make equipment that matches that."
So, I am thinking the instructions that came with the electronic lighting control devices (those from yesteryear) said to connect the hot, neutral, egc and used their EGC connection for the few ma required.
I'm also thinking there was never any NEC code provision to do this. I looked through a 2005 - didn't see anything. Maybe I missed it. I don't recall any AHJ having a fit over no neutral for the elcd.
Remind me - what was the justification to do this?
