Due to their exposure to the open air because of the cable trays, the wires contained within need a very durable outer covering. The regulations dictate that the cables must either be Type TC (also known as Tray Rated) or must be metal-armored (Type MC). (i) Metal raceways, cable trays, cable armor, cable sheath, enclosures, frames, fittings, and other metal noncurrent-carrying parts that are to serve as grounding conductors, with or without the use of supplementary equipment grounding conductors, shall be effectively bonded where necessary to. NEC Article 392 explains cable trays, their components, appropriate wiring methods for cable trays, and instances where they are and are not permitted for use. It also focuses on construction and installation practices for cable trays. Here is the summary of the main points found in NEC Article. A raceway is a pipe (conduit) that entirely conceals the wires.

Intumescent coatings are reactive fire-protection paints applied to the tray surface—often factory-applied to control thickness and quality. Under fire exposure, the coating expands to form an insulating char layer, slowing heat transfer. ALTIC 007 is a water-based, intumescent fire retardant coating designed for cables, cable trays, and penetrations, providing up to 4 hours of certified circuit integrity as per NTH Mumbai testing. Our products, ideal for contractors, painters, and new businesses, meet fire and building codes, ensuring safety against fire risks in construction projects. So, what exactly is fire retardant. Most EPC specifications narrow the choice to two mainstream solutions: fire wrap systems (encapsulation) and intumescent fire-resistant coatings (reactive coatings).
