[i]Iberville Octagonal Box 1-1/2 Inch AC90 Steel Stud[/i] Trying to figure if I can mount a 30lbs fan (as per specification full installed weight) to this box? We are in a townhouse condo and don't think we have access to attic. I did find label into the box and it's exactly the box in the pic. The two screws on the box that would be used for fan mount would take 8-32 machine screws. I am thinking of using them with hex nuts for extra protection. But is this box ok for mounting the fan? Or if not, how do we switch it, as not sure how to get in attic. ​also it has two pipes if wiring coming into it with bigger nuts to hold the pipe. It seems pretty stable if it try to move by hand. Thanks in advance. Same is available in home depot : [url=https://www.homedepot.ca/product/iberville-octagonal-box-1-1-2-inch-ac90-steel-stud/1000805183]link[/url]

Hi All, I am installing a new ceiling fan/light in my daughter's room. I removed the old fan/light and am now somewhat confused by the wires in the ceiling. To start off, there is one wall switch that controls it. In the ceiling, there is a copper ground wire, two white wires twisted together, a red wire, and two black wires twisted together (the green-yellow wire in the below picture is from the first part of the fan that I installed; its not from the ceiling). I didn't think to write down the old connections, but I do know that the white wires were connected to something in the old fan/light (presumably to the white wire), the copper ground was connected to the green in the old fan/light, and the red wire was (I'm 99% sure) connected to a blue/black wire in the fan. (By blue/black, I mean that the old ceiling fan had a blue wire and a black wire, and they were twisted together, and then they were connected to the red ceiling wire. I know they were twisted together because I still have the old part, and they are twisted together. I am 99% sure that the black/blue twist was connected to the red wire.) The two black wires in the ceiling were not connected to anything. I am 100% positive of this because the wire connector nut is still on them, and I didn't need to remove it to disconnect the old fan/light. See below picture. I am attaching a picture of the ceiling wires now. Can anyone tell me how to connect these wires to the fan wires (which have black, white, green-yellow ground [as in the picture already], and blue)? Also, is using electrical tape over the wire connector nut overkill, or is it worth doing? I've heard both. Thanks!
