I'm a member of a sister site to this one so I thought I would ask this here.
I'm replacing my ceiling fan the kitchen of my old house and coming out of the ceiling was white , black and brown wires.
The old fan wasn't using the brown wire and it was just hanging there with the end cut off so no bare wire was sticking out.
There is no ground as I was expecting a green wire for that.
What would the brown wire be for and is it safe to hang there? I know just because it was done that way doesn't mean its safe or the right way.
