308.3 Protective Assembly Construction and Installation
JUMP TO FULL CODE CHAPTER
Reduced clearance protective assemblies, including structural
and support elements, shall be constructed of noncombustible
materials. Spacers utilized to maintain an airspace
between the protective assembly and the protected material or
assembly shall be noncombustible. Where a space between
the protective assembly and protected combustible material
or assembly is specified, the same space shall be provided
around the edges of the protective assembly and the spacers
shall be placed so as to allow air circulation by convection in
such space. Protective assemblies shall not be placed less
than 1 inch (25 mm) from the mechanical appliances, devices
or equipment, regardless of the allowable reduced clearance.
