I'd like to replace an existing light switch with a new, "smart" light switch as one of three switches in a three-gang box.
Looking in the box, I see three pairs of hot and load wires, and three ground wires, but there is also a bundle of five neutral wires pigtailed together.
I don't understand why there are so many neutral wires, or how I'm supposed to attach the neutral terminus of my switch to this bundle. Do I simply remove one of the five from the pigtail and connect it to the switches' terminus, or do I get a brand new (6th) wire, attach one end to the terminus, and pigtail the other end to the bundle?
I'm in Canada, for what it's worth.
