Hello
I am installing a ceiling fan. Their was never a ceiling fan in this room before so I also have to install an outlet box. As luck would have it (not sure if it is good or bad luck) the place where I want to put the outlet box is directly under a ceiling joist. The ceiling joist is 4" high by 1.5" thick. To put in the outlet box I will have to cut a 1.5" high by 4" wide section of the joist out so I can recess the outlet box. My concern is that this will weaken the joist to the point it may not hold the ceiling fan or could effect the ceiling itself? I know nothing about wiring so I also don't know if wires can come in on the sides of outlet boxes or if they have to come in from the middle top which would be centered on the joist and blocked? Alternatively, could I install the outlet box mounted on top of or on the side of the joist and just run a wire from it through a small hole in the ceiling? Would like to know the answeres to the questions above but would also like to get peoples oppinion if I should just leave this up to the electrician since I have to have them come out and run the power line and create a new switch anyway.
Thanks
