Hello, I have a question about installing a dimmer in a room. My house
is quite old.
I am going to be replacing an older dimmer that isnt working well.
This is how it is installed now: The actual dimmer itself, has only 2
One wire goes to a thick black wire and is connected with those
plastic wire connectors.
The second wire from the dimmer goes to a thick red wire also
connected with those plastic wire "caps".
I realize that its pretty simple to connect a new dimmer, however, I
noticed that new dimmers have 3 wires in them. Where should I connect
the third wire? this is a ground i imagine. If there is no room to
connect the ground, does it matter to have it at all? I mean the old
dimmer had only 2 wires, no ground.
