I have a four-gang box that I'm installing new dimmers in. Currently all of the neutral (white) wires coming into the box are connected together (and not to the dimmers). The new dimmers require connections to the neutrals.
There are three bundles of wires coming into the box, two of them having their own triads of hot, neutral, and ground. The third bundle has two triads of hot, neutral, and ground wires.
In this third bundle, it's unclear which neutral is paired with which hot. Does this matter when connecting my new dimmer or can the dimmer be connected to any random pair of neutral and hot wires?
