HI
I am working on town homes and would like to know if the opening on a 1099 allied box should be sealed in a fire wall.

1099 boxs are 2hr rated but ones you put wires in the box there will be a open area around the wire.

If I do need to seal this box could I get the info that says that I have to do this.

thanks
matt

If I read this right you need a putty pad to establish the fire rating

It sounds to me from that listing like the putty pads are only required if you don't meet the minimum separation of boxes. Am I reading that wrong?

The UL listing mentions several times that the gap between the box and the wall must be less than 1/8"- sounds to me like it's implying that some gaps less than 1/8" are acceptable, and cable entries may not need any special sealing.

Yes you are right Steve. The joys of fire rated assemblies ;(

I was reading the wrong assembly description.

if you install 2 boxes in the same stud space of a dimizing wall-- one in "townhome a" and the other in "townhome b" then you would need putty pads for sure. as long as there's only one box in each stud space you shouldn't. at least that's how it's done in washington d.c. is that how everyone else sees it?
