Hello all.
I understand the very basics of electricity. I understand sharing a neutral between circuits is not proper wiring.
With that said, here are a couple questions.
1.) it appears, sadly, throughout my home, any dedicated switch in a 3/4 way setup, there are no neutrals in the switchbox. If a switch is wired to a single light or an outlet, the neutral IS in the switchbox. When turning off the breaker at the panel, in some cases, all switches in the same switchbox lose power. Is it safe to “assume” if a neutral is in the switchbox for a 1-way setup next to a switch that is part of a 3/4 way setup, I can “steal” that neutral for all switches since it is the same circuit? Or is it that multiple circuits can be wired to the same breaker and therefore this wouldn’t be a safe/approved way to wire a switch? I do know, in some cases, there is piggybacking done in the panel at the breaker if that matters, which I also know isn’t proper.
2.) if the above wiring is safe, would I be able to use a single inovelli dimmer/switch at the switchbox location where a neutral exists for reasons mentioned above and not need smart add-ons one the other locations where the possibility of neutrals may not exist? I know I have to make sure the line to the switch box needs to be located in said switchbox.
Thanks for any ideas and advice!
