installing new outlets

matt756January 23, 2011

hello everyone, im installing new outlets in my aunts house because her wall has water damage. there were no previous outlets where i am putting these new ones. my question is how big of a hole do i need in each wood stud for either 12 gauge wire or 14 gauge wire?

i was planning on 1 to 1.5 inches for each hole.

there will be only one cable in each hole.

i am also going to be putting in cable tv and telephone jacks. should i use a 1.5 inch hole for those also?

thanks in advance

1" is more than sufficient, even for future wiring.

Make sure you drill in the center of the stud. Also go no larger than you need. 1/2" to 3/4" is plenty for one 12/2 romex cable.

Matt, just so you know, most areas allow homeowners to work on their own wiring. That doesn't include your aunt's unless you hold the deed to the house. You won't be able to get a permit.

In theory at least, you could be held liable if something goes wrong with your unpermitted work.

If your wiring gets dinged by the home inspector when it's time for her to sell, she'll probably have to pay a pro to come out and re-do your work. That won't be cheap.

If the edges of the hole are less than 1.25 inches from the faces of the stud a nailing plate is required to protect the wiring.

Have your Aunt pull a permit.

In most places it is only 'for hire' work that is prohibited.
You can 'help' your Aunt do the work.

i will have my aunt pull a permit.

i have to go over a window. when i come down in-between the studs do i have to staple the wiring in place to a stud?

also can i run cable TV and telephone in the same hole or do they need separate holes in the studs?

thanks for all the help

matt-
The reason to keep the holes to the smallest size manageable is that bigger ones unnecessarily weaken the studs and the wall. And, yes, since you have open walls you want to staple the cable to the studs. If you are using plastic boxes, you should staple the cable within 8" of the box.

If you fish wires into stud cavities no attachment beyond the cable clamp at the box is required.

They can go through the same hole.
