Guide Information for Fire-resistance Ratings

705.8712.3.2300.21300.21

USE AND INSTALLATION

This category covers wall-opening protective materials investigated for use in fire-resistance designs as detailed in Fire-resistance Ratings - ANSI/UL 263 (BXUV). The protective materials are proprietary compositions used to maintain the hourly ratings of fire-resistive walls and partitions containing flush-mounted devices, such as outlet boxes, electrical cabinets and mechanical cabinets.

The Metallic Electrical Outlet Boxes section under WALL AND PARTITION ASSEMBLIES in BXUV specifies the conditions under which certified metallic outlet and switch boxes may be installed within fire-resistance-rated wall assemblies constructed with bearing and nonbearing wood or steel studs and gypsum board facings. In addition, Outlet Boxes and Fittings Certified for Fire Resistance (CEYY) includes certifications for nonmetallic outlet boxes along with the conditions under which such outlet and switch boxes may be installed within fire-resistive wall assemblies. With either type of outlet or switch box, it may be possible to install the boxes under less stringent conditions when such boxes are used in conjunction with wall-opening protective materials. The use of wall-opening protective materials may allow for (1) reducing the spacing between boxes contained on opposite sides of the wall, (2) increasing the size of the boxes, (3) increasing the density of boxes installed, and/or (4) allowing the use of boxes on each side of staggered stud walls. The individual certifications indicate the specific applications and the method of installation for which the materials have been investigated. Unless otherwise specified in the individual certifications, all conduit connectors used in conjunction with metallic outlet boxes are intended to be steel.

Electrical devices are intended to be installed in accordance with ANSI/NFPA 70, "National Electrical Code."
