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.
You connect all the grounds together with a ground crimp connector. A wire nut is not sufficient to meet code. And then if the box is metal, you connect the crimped bundle to the box. In the junction box, I see 4 types of wires. One bare copper wire is connected to the metal box too which I believe is the ground wire. Two black wires . The instructions on the app were very very clear. I was just wondering why all the wires carry voltage. electrical; thermostat; baseboard; voltage; Share.
