Installing a new ceiling fan, where none existed. I have an existing power outlet near the ceiling that was intended for a hanging lamp and is already hooked to a room switch (1960’s house). Can I remove that power outlet and use that existing box as a junction box to splice my cable? I would then just put a dummy plate on the front of the box. This all makes sense to me, but I wanted to check with people that obviously know more than me. Haha. Thanks in advance!
