So I’m wiring some 3-ways (GE z-wave plus add-on switch) and its been a while since I’ve taken a class in electricity. Does anyone see anything dangerous with the below?
Basically I have a hot into the light fixture, which leaves me no neutral for the load switch, but I have a switch off a different circuit with a neutral in the add-on box. So I’ve used the neutral in the add-on box for the other circuit for the add-on switch and shunted the neutral from the add-on box over to load box (on the neutral wire) in the 14/3 wire running from the add-on box to the load box. (The black wire in the 14/3 is capped on both ends as I’m only using the traveller/neutral.)
It works, but the neutral for the switch (but not the load) is coming off a different circuit. Anything dangerous with this? What if the breaker was thrown for the other circuit…the switch may not work but no fire hazard?
Edit: After reading some more it seems that a common neutral could cause an electrocution hazard if the first circuit is opened and the second is under load. But in my setup the only load crossing circuits are the z-wave switches themselves… Anyone know how much amperage the switch itself draws?
(On another note, I located a neutral wire wired to a GROUND wire in one box. WTH. Not a bootleg ground…actually using the ground as the neutral despite there being a neutral in the box…)
