Where does NEC specifically note that switching of neutral on a 120 VAC control ckt is prohibited? I have a fabricated control panel that's full of control ckts with contacts on both sides of 120 VAC relay coils.
Even with a bit of searching, I can't seem to find the specifics.
While on the subject, how can a standard OL contact be wired between the coil & neutral in 99.99% of 120VAC control circuits to begin with? I've never been fond of that arrangement, even though it's been the industry-standard almost forever.
