Getting sick of UPB deviecs that aren't in the mode they say they are. Also second the no neutral. A nightmare rewiring old three and four way switches that had no neutral at one end.
here's a question... The neutral is required because the switch itself needs power and so it has to get power between the hot lead and the neutral lead, but, in N.A. wiring (and presumably elsewhere) the ground wires and the neutral wires are tied together in the breaker panel. So, the question then becomes, can a switch be run by connecting the neutral connection to the box ground? I know somebody is going to say that this would be a violation of the electrical code, but my point is, despite the code, why not? The tiny bit of current required for the switch shouldn't be a problem. The light itself would not be using the ground as the return path because it has its own neutral.
Ok, so I figured I better try it out before posting, just in case I was missing something, and, it does in fact work as normal. The amount of current draw from the switch is the same when wired through the neutral as it is through the ground and stays the same whether the light is on or off, meaning the current for the light doesn't go through the switch neutral. What I found more interesting was that this was tested on the new Jetstream light switch and the switch current was 100mA which is 11 watts of power! Now I needed to know what was going on inside the switch... I tested the current requirement for the electronics themselves, before the 3.3v regulator, and it is less than a 1/2 watt. Where the other 10+ watts are going, I don't know at this point.
So, maybe I answered my original question about the ground as the switch return, maybe 11 watts is just to much to "sneak by"
