Again, thanks to everyone for all their valuable information as I wire up my Recording Studio addition. :) You guys are great! ;)

I have another question reference the use of Junction boxes. On a couple of my framed walls, where I wired in outlets, some of the outlets (for like Exit Signs) are located up around the top plates, over doorways of the framed walls. Also at that location within the framing (but lower of course) is where I have light switches located for the rooms overhead lights for that area.

Anyway, what I was wondering, can I run out of an outlet box, up and into a junction box which will be located above a drop ceiling which will be easily accessible, then branch 1 feed to the overhead lights and switch out of that junction box,, then also run out of that same junction box a feeder to the rest of the outlets down the wall?

I assume that's what junction boxes are for, but just wanted to make sure there wasn't some code change or something I need to know while using junction boxes. I understand that junction boxes must be accessible, and these will but they will be above a drop ceiling. Is that OK to do? (Is that still considered "accessible"?)

I attached a amateur diagram of what I am out to accomplish.

Thanks guys ;)

I would do that. Don't skimp on box size. Centrally located, can save wire.
Install where it can easily be accessible without moving everything, unless changes or known NOT to change. The 4" X 4" works great, if you need more room, it allow box to double its volume.

Is it the same circuit that control's it ?

I am not sure exactly what your asking. But yes the outlets and the overhead light are all on the same circuit. And that switch obviously only controls the light only. It's a 20A Circuit (will be used for Stereo type equipment, TV's ect) and there are maybe 10 outlets on the circuit.

Does that help?

And Strat thanks for your replay as well. ;)

Why is a junction box needed? Why not run cable from box to box?

I agree, no junction box best, I would use "Smurf"(ENT), Maybe have spare smurf from Panel to box in ceiling for changes or additions.
Personally, I don't like Romex, Especially on my own stuff.

I actually wanted to use the junction box at that location mainly because with the blue (Lowes/Home Depot) outlet/switch boxes that I am using, anything more then like 2 wire connections behind the device seems to make is real crowded in the box. I know 3 connections, using 12/2 wire with wire caps will fit, but it just seems cleaner and more roomy if I do the "extra" circuit connections (like for the overhead lights etc) in a junction box. :confused: The rest of the outlets in the line/circuit just go from box to box down the line.

Is it OK to do it this way??

Also not sure what "Smurf" is? I already have the circuits wired with 12/2 Romex, just haven't installed the outlet, switches or lights yet. (guess that's called the "rough in")

Thanks again ;)

Either use the 22 cubic inch blue plastic nail on boxes, or use the nail on 4" square boxes with 1 gang mud rings.

Smurf is flexible plastic tubing, that uses PVC connectors and couplings, 1/2 and 3/4 common. Goes to 2 ", or more. I would use PVC larger than 3/4" E.N.T.(Electrincal Non metallic Tubing).
Nothing wrong with it. I like a lot of room in box(Future Expansion, Dimmer)
When it first came out, it was blue, we allways called it Smurf, You can get more colors now. Has ridges in it. You can always pull more wires, switchleg, 220 to wall AC. Romex makes it more destructive, when modifying . Your application sounds like no problem.

Thank you both very much for your responses. Helps a lot and much appreciated. ;) ;)
