fire stopping electrical boxes Electrical box inserts are designed to restore ratings and fire resistance-rated walls where electrical boxes have been installed. This can help contain fire and potentially minimize damage to a building infrastructure. Metal electrical boxes were used long before plastic (PVC) electrical boxes were introduced. Strong, fireproof, and incapable of melting, metal boxes offer the greatest level of security for all electrical wiring applications.

Separating walls form a fire barrier between compartments. However, recessed switchboxes often need to be installed in fire resistant dry wall or masonry structures. These recessed installations jeopardise the fire barrier function of the compartment wall. Standard switch boxes also compromise the fire resistance of walls.BESA or universal boxes must have intumescent gaskets fitted to stop fire penetrating. Furthermore, metal socket boxes must have gaskets installed where they’re back-to-back. This also includes if cables pass through walls.
