Adding a couple additional ceiling lights to attic
 
1 Attachment(s)
Hello,

My attic only has one light and I would like to add a couple others pig-tailed from each other.

I like this placement as they are high enough to be out of the way from heads and shine downward. I was planning on running the romex through each roof rafter with a 1/2" hole in each - my only concern is its proximity to the roof - is this an acceptable route?

Kinda not the best move and I will NOT drill the roof rafter at all for safety reason.

There is other option you can go is grab 1X4 pineboard and nail it across hortonally and run the cable from there this is genrally safer than try to drill thru the roof rafter due you can weaken them down.

Merci,
Marc

What if I get the plastic wire holders and just run it on the ends if each rafter?

..or maybe just move it to the truss instead - I just didn't like the angle and the thought of hammering into something less supported.

My main concern was if there was ever any roof work done the possibility if a nail going through the wire...

There is a reason why I mention pine board in first place so that way when someone do the roof work it will not hit the new cable at all plus will have some kind of protection as well.

When you bring the cable up to the 4 inch round boxes keep at least 1.5 inches away from roof surface I rather keep it away more if possible ( that one reason why I use pine board for this ) and Don't be too suprised when someone do work on roof and they use very long nails and I have see it happend before.

Merci,
Marc

Those are not rafters. You have trusses. You are not supposed to drill or alter trusses in any way without an engineer stamp. Surface run the cable.

adgjqetuo 03-31-2013 08:43 PM

Yeah - I'm glad I took time to re access - I'm going to over mount the romex.

Marc, I'm not sure I fully understand what you are suggesting with the 1" board - can you try to explain a little future so I can possibly replicate what you are suggesting?

I like the location just not the proximity to the roof.

Whatever you do, Definitely don't drill through the trusses.

Bonjour Mike.,

What I am refering to the T interscetion of the trusses just put a pine board right on that spot and nail it and run 12-2 or 14-2 NM cable on that and be done with it.

It will look little better and safer this way. ( the other reason why I mention pine board so no one can grab the cable for some reason in attic space )

Merci,
Marc

Mark is referring to runner board nailed across the trusses to support your cable. Take a piece of 1x3 and nail it across the trusses between the boxes and then fasten your cables to that.

Excuse my Quick paint job - but is this similar to what your talking about?

Red - backboard (will a 3/4" piece of plywood work for this)?

Black - 2" decking screws to hold the board in place

Blue - light box

White - romex

Yellow - wire mount

Also - just as FYI info - where the picture is showing the boxes it's about 8' high there. The roof rafters continue up for about another 5-6 foot in the air (looking left)

Are you just adding the 2 lights?

I would put in a 4 foot florescent fixture.

adgjqetuo 04-01-2013 11:04 AM

There will be 3 total - the room is 20' wide so I have one in the center and one on each end.

The paint drawing is to see if in getting the same idea but not the actual placement - each box will be about 4-5 rafters apart.

What if I attach the light box to a small piece of 2x4 then attach the 2x4 to truss itself via 2.5" screws? Will that cause any issues?

This way it's further down from the roof and I'm not hammering force into the truss (only the separate piece of 2x4 when detached).

Don't make it tougher than it has to be. Your boxes are fine where they are. Just nail up a long firing strip between the boxes and staple your wire to it.

No. Take a piece of 1x3 lay across four a five trusses or as far as you need to run cable
and nail it on.

Thank you for your help - I see exactly what you mean now.

My only concern is the wire doesn't go into the box as you have shown due to where the box is mounted.

You would have to run the wire into the box as I dew out below which could still cause it to be damaged if nailed through the roof. How would you suggest protecting the wire? I have extra 1/2" hard plastic conduit around - would that do the trick?

I like your idea because it's less work then removing the exsisting boxes.


However - would this be another alternate soulution to my problem if the wire I have shown can't be protected?

Red = 2x4x10 screwed into the truss with pre-mounted light box.

Sorry for all the back and forwth - I appreciate all the help!
