is there a distinction between "in-wall" vs "through wall" ?


hanging plasma on the wall. the outlet and cable are several feet from the position where i'd like to place the TV. The room BEHIND the wall where i'd like to hang the TV has an outlet and cable just 3 feet away.

Yes, in a perfect world i would split off another outlet and put a receptacle behind the TV, etc etc, but this DIY-er can't do it on his own without opening up the sheetrock and making a big project out of it.

I am considering just making a 3 inch opening in the wall behind the TV and "poking" the power and TV cable through the wall and into the outlet a couple of feet away in the other room. The other room is just an office and i don't care if those wires are hanging down the wall.

This isnt a case of me "fishing" multiple feet of wire behind a wall, i'm talking literally poke it directly from one room into another.

I know its sloppy, but am i violating a specific code that says wires such as TV type power and cable wires cannot be passed through walls? The total amount of wire between walls would be 4 inches.


thanks..

i don't THINK it's a violation, but i may be wrong. but the open wall is an invitation to possible insects/rodents getting in. it's like running an extension cord around a corner to another room. heck, i should think it's even safer! but just wait....if i'm wrong, someone will let us know shortly, i'm sure.....

Sleeve it with a piece of PVC.

i'd go a step further and get hollow caps/rings to glue on each side too.
keep out the riff-raff....

400.8 USES NOT PERMITTED. Unless specifically permitted in 400.7, flexible cords and cables shall not be used for the following:... (5) Where concealed by walls, floors, or ceilings or located above suspended or dropped ceilings.

In my opinion, the intent of that code is to prevent people from running those cords vertically or horizontally IN walls, concealed. Going directly through the wall...Albeit sloppy...Wouldn't get my hackles up.

OK, looked it up (last cite was from memory), it's 400.8(2) uses not permitted.... (2) Run through holes in walls, structural ceilings, suspender/dropped ceilings, or floors.

I'd sleeve it in conduit, oversized - 2" min
Since the cord will not be concealed I do not see a code issue
As long as you are going straight thru the wall & not angling down to the outlet

A friend actually cut a hole in a wall & mounted a reg CRT TV in the closet. The screen was flush with the wall, looked very nice

i like the PVC idea, i'll just cut the hole the same size as the PVC ring. I'm probably going to do this anyway, code or not, if i ever sell the house i'll just pull the wires back through and run everything along the floor for an inspection. (and the wall is very easy to patch).

good ideas.. thanks guys.

michael, is that specific to house wiring, or does that include appliance cords?
i've seen holes in kitchen cabinets to plug in appliances.
and for sure, use at least 2" ID pvc, you need to easily pass plugs through.
if you went 4", that allows easy viewing of the entire wire, so wouldn't that be NOT concealed?

If it's sleeved then its no longer a hole in the wall
Its a short section of conduit

It states flexible cord, doesn't specify extension cord or appliance cord
DW cord is many times passed thru to sink area, same with the microwave
But then its a hole in cabinet, not a wall

I'd say not allowed, as stated by Michael.
