This picture is from a new building. It is not a 3-way light.
there are three black wires coming out from the wall. One runs directly to the light switch. Two get connected in the blue connector, and then one runs to the switch.
I can see the white neutral at the back.
Where is the ground? And why are there three black wires?
I would like to replace this switch with a smart switch that requires neutral and ground connections.
