I am in the process of hooking up 2 GE Z-wave light switches. I've hooked up multiple smart switches but ironically only one has needed neutrals (these 2). They are both going in a double gang box side by side. I had a few concerns: (BTW they both went to the same breaker switch)
One of the wires was red going to the previous switch, I hooked it up like I would any normal hot wire and it worked...is it just another color for a hot wire? (They've always been black or grey in this house)
Each switch required a neutral. I took both GE neutrals and tied it into the bundle of other neutrals (Which was like 2-3 wires in a wire nut). Sidenote: This made 4-5 wires in a wire nut...it fit fine but was a little tight. Is this ok? Is there a "max limit" or just whatever you can fit
This is more of just me being paranoid but man with all the wires and how tight it gets in those gangboxes...it makes me feel like something is going to snap or come unhooked (even though I make sure everything is super tight). I guess if that was a problem though more houses would be burning down ha...just always makes me uneasy.
