By a horizontal distance of not less than 24 inches where the wall or partition is <br />constructed with individual noncommunicating stud cavities. <br />1.2. By a horizontal distance of not less than the depth of the wall cavity where the wall <br />cavity is filled with cellulose loose-fill, rockwool or slag mineral wool insulation. <br />1.3. By solid fireblocking in accordance with Section R302.11. <br />1.4. By protecting both boxes with listed putty pads. <br />1.5. By other listed materials and methods. <br />2. Membrane penetrations by listed electrical boxes of any materials provided that the boxes <br />have been tested for use in fire-resistance-rated assemblies and are installed in accordance with <br />the instructions included in the listing. The annular space between the wall membrane and the <br />box shall not exceed 1 <br />8 inch unless listed otherwise. Such boxes on opposite sides of the wall <br />shall be separated by one of the following: <br />2.1. By the horizontal distance specified in the listing of the electrical boxes. <br />2.2. By solid fireblocking in accordance with Section R302.11. <br />2.3. By protecting both boxes with listed putty pads. <br />2.4. By other listed materials and methods. <br />3. The annular space created by the penetration of a fire sprinkler or water-filled fire sprinkler <br />piping, provided that the annular space is covered by a metal escutcheon plate. <br />4. Ceiling membrane penetrations by listed luminaires or by luminaires protected with listed <br />material that have been tested for use in fire resistance-rated assemblies and are installed in <br />accordance with the instructions included in the listing. <br />1 <br />CM <br />SD <br />DR <br />A <br />F <br />T <br />I <br />N <br />G <br /> <br />& <br /> <br />D <br />E <br />S <br />I <br
