First of all, this run is for data lines, not AC but this seems like the best forum... My house is a 2 story with slab floor. I need to get some wires from the attic to the lower floor. On the lower floor, one side of the wall is a garage so I could open that wall if necessary (it is finished but not painted). The same wall on the upstairs is a bedroom/hallway which is finished and just painted etc. so I don't want to cut open drywall or even try using a right angle drill through an existing hole. First off all, the upstairs room already has a wall plate with cable in the wall/stud bay I plan on using and I might as well use that same stud bay space. It's possible that there is already a hole running through the floor for the cable. If not my plan would be to drill from below through the floor plates from the garage. So before I go off half cocked I thought I'd run my plan by someone in the know.. 1. Open a small hole in garage next to ceiling right below stud bay with cable in bedroom. Try to determine if there is already a hole with cable. 2. if there is no hole, use a right angle drill to drill a hole upwards into stud bay. Having an existing cable access box hole will allow easier fishing of wires past access. Does this sound like a reasonable plan? It appears that all of my AC wiring goes from the attic straight down through to the second floor (becuase it's slab floor) but your not really supposed to run data cables (i.e. CAT5e) next to AC and the holes probably wouldn't be big enough anyway. Thanks

We originally had a electric cooktop and a separate wall oven. We are now installing a range/oven where the cooktop was. When I disconnected the cooktop, I realized it was hardwired. It was connected with 3-wire (14gauge) flexible conduit coming from the side of the cabinet into a box on the wall under the cooktop, then to the cooktop with more flexible conduit. Written on the cabinet was "220v junction box behind this cabinet". In order to access this, I have to go in the basement and come up from under and behind the dishwasher. It is set on an angle in the corner. I could see two of the flexible conduits coming from the wall. One going to the cooktop and the other to the oven. Accessing this junction box in next to near impossible without removing the dishwasher. Can I just connect the new range with the existing wires and leave the old oven connected? Or, do I need to disconnect the old oven and only have the new range/oven connected from the junction box? Thanks for any help.
