What a surprise to see that the author of this is a member of NEMA.
How would this play out with a 3-way and 4-way switching arrangement?
Does this mean a neutral conductor in every switch box regardless, even where it wouldn’t normally be required for a lighting control? Just wondering, because technically they would all seem to be controlling lighting loads.
IMO, I think the exception for raceway is because they assume you will be able to pull a neutral if needed at a later date.
BTW, digital timer switches that run only on batteries have been around for a long time, so why can’t manufactures just produce lighting controls that use batteries.
Then they can sell a lot more batteries to customers that actually use their lighting controls and not to screw everyone else who doesn’t want or need their lighting control products.
