I am installing a New Light/fan fixture has 6 wires coming from it. White, Green and black for the fan. Same three wires for the light. My main wire from the house has 3 wires and a copper wire; a red, brown, black and the copper. I have two switches on the wall, one for the light and one for the fan. How do I connect these wires?

Where do you live? So the line feeding your switch box has "copper wire; a red, brown, black and the copper which means to bare coppers and no white neutral, right? Or are you talking about the wires that are in the ceiling box and not the swicth box?
