So, straight away, Zone 0 is a no-go for cable trays. In Zone 1, you need trays designed to contain an explosion or stop sparks getting out. Chemical plants have risks like explosive gases, dusts, or vapors. It's serious business – around 15% of chemical plant explosions happen because of. PLTC cable was permitted in dust locations without being in a single layer or with a cable space between cables. The 1996 NEC. Recognize electrical cable tray misuse that can lead to electric shock and arc-flash/blast events and fires caused by overheating. 305(a)(3), or comparable standards promulgated by States. Deploying the proper cable infrastructure can be accomplished by following these three steps: While these three steps sound simple, interpretations of the regulations can present some ambiguity. All the details play an important role in a hazardous location installation. Cable must ha minated with listed fittings.
