Everything Joe said. I could not have said that better myself. If one were to zoom in on that fan box from Home Cheapo one would see that a junction box made specifically for a fan installation has mounting studs for the 8-32 screws as well as the two standard 8-32 mounting tabs. One would want to make sure they use the studs in lieu of the tabs in order to get that 150# ratings. Using the standard tabs will only give you one or two threads for the 8-32 screws and that is not enough. Common sense stuff most would figure out anyway but you would be surprised.
As Joe also mentioned, it is extremely important and worth mentioning again to leave the wires long enough out of the boxes to the device being terminated. The 6 inches required by code sure facilitates the folding of the wires back onto themselves and makes tucking them into the box when trimming off much much easier. A rookie mistake is in thinking the shorter the wires, the less to fit into the box but in this instance that is not the case.
One point Joe did not touch upon is the size of the boxes. USE DEEP BOXES. I use only the 3 1/4" deep ones.
Happy wiring!
Good thread guys.
