I live in Ohio in a home built in the 50's. A very large back porch was added onto the home years later with a roof. It has the typical vinyl ceing. It has one light in the center of the ceiling controlled by a switch inside the home. I wish to remove the light and replace it with a non-lighted ceiling fan. I want to run power from the fans junction box to a separate one. My plan is to add 4 each of 12' LED tape light runs in metal channels that will be powered/switched from the switch in the house. The fan will have the pull chain to control it so when I turn the switch off in the house it will kill power to the fan and the tape lights.
Now for the meat of this post; I assume (I may be an idiot, not a complete one) I have to cut an access hole in the vinyl and add a nice looking access panel. Am I allowed, by code, to cut the plugs off of the two power supplies and hard wire them into a junction box? Do I have to screw a box in the ceiling to hide the two transformers (one for two runs) directly above the access panel or is this not allowed at all? Any and all help would be appreciated. I have to do this as cheaply and easily as possible while remaining in code. Thanks.
