Cable tray opening through brick wall

Home / Cable tray opening through brick wall

The best and easiest way to run electrical cable through a brick wall is to drill a hole that's the right size, put a conduit in it to protect the cable, and seal up the hole so water, bugs, and fire can't get in. These intumescent urethane foam blocks are installed in openings by compressing and stacking into the opening in a brick-like fashion. Scope: Firestopping for busway, cable trays, cables, and trunking passing through walls in enclosed electrical installations. Non-curing and re-usable firestop block designed for the easy re-penetration of retrofitted cables. UL Listed Systems Concrete Wall - C-AJ-4056 3 HR F-Rating, 3/4 HR T-Rating Gypsum.
