How to Wire a Security Light with Attic Wiring Options

Electrical Wiring Question:
I would like to add an additional security light in a gable end of my home. The attic space is not used and is full of blown insulation.

Wiring Option 1
The only clear run I can identify is within the webs of the trusses.
Can wiring be run between the webs of pre-manufactured roof trusses? Will conduit be required?

Wiring Option 2
Connect to wiring of an existing security light.
Run the wire in the eave, up into the attic area, on top of the insulation and to the location of the new fixture (unsecured). Sorry, about the length, electrical wiring is definitely not one of my strong points.

Thanks in advance for your help- Darin.


Hi Darin - Great Electrical Question!
Electrical Wiring in an Attic
If the wiring is run on top of the insulation, will this area be accessible?
If so the wiring will need to be secured and installed in an area where it will not be vulnerable to damage.

It is ok if the romex or Type-NM cable is covered by insulation.
Be sure to match the existing wire size.

Let me know if this helps.
