Are cable trays sealed
These create a sealed entrance for the cables to make their way inside, and must be carefully weatherproofed. In some cases, sealants such as GRP weathering systems may be used, enabling a cable tray to penetrate a wall without ductwork or other protective structures. Where cables pass through shafts, walls, slabs, or enter electrical panels or cabinets, openings shall be tightly sealed with firestopping materials in accordance with. WSP weatherstops are designed to seal penetrations of any type in walls or floors by cable tray, cable conduit, pipe and/or bus duct. The WSP system utilizes a powder coated or galvanized steel frame that encompasses the entire tray or duct at the point of penetration. and land the wires inside the enclosure in a small Crouse EAB junction box, then come out of that with cable and tray. The effective weatherproofing of cable trays helps to keep weather out, preventing damage to the building envelope, avoiding thermal breaks, maintaining the indoor environment and helping to keep the various cables and wires protected. It can also help to keep out birds, rodents and insects.
