Re: Ceiling Fan Junction Box
You will have to post the images to an image hosting site, then link them here.
You need to install a fan rated box. Just because a box has a metal clip on the side, doesn't mean that the box itself is capable of supporting the fan. Most fan boxes are metal, or have metal incorporated into their structure to support the fan. The thing with fans is that you're not just carrying their weight, which can be substantial, you are also introducing vibration and movement, which can "work harden" plastic and cause failure.
I'm guessing that you've got brown electrical boxes, which is Bakolite, and incapable of supporting a fan.
