I'm trying to install a ceiling fan in my new construction home.
The fan's instructions call for 3 grounding wires (green, green/yellow stripe, or bare copper) to connect to the hanging bracket, 1 ungrounded wire (black), 1 grounded wire (white) and optionally a second ungrounded wire if I have a dual switch (I don't think I do?)
In my junction box provided by my builder, I've got 3 red, 3 gray, 1 purple, and 1 yellow.
Can someone help explain what my wires are and optionally how they should be used while wiring my fan?
Edit: I live in Chicago if that helps.
