To achieve compliance, electricians must use approved through-penetration firestop systems, which are assemblies of specific materials tested and certified for this purpose. Proper firestopping for electrical installations is a critical life-safety requirement that every licensed electrician must master. One way to prevent boxes from reducing the walls fire rating and thus meet the IBC performance requirement is by. Other recessed boxes installed in fire rated walls can include washing machine connections, dryer exhaust recesses, ice maker connections, and medical gas connection boxes. The International Building Code, which is adopted in most US jurisdictions, requires that all recessed fixtures be installed. These nonmetallic electrical boxes are installed as membrane penetrations through a fire-rated separation wall between two apartment units and are protected by listed putty pads.
