Can explosion-proof electrical boxes use cable trays
They consist of support channels, cable trays or exposed cables; the entry of cables into the flameproof or increased safety enclosures and equipment is normally done through cable glands. Let's break down what you need to know about explosion-proof requirements for cable trays in these environments, keeping it simple and clear. Chemical plants have risks like explosive gases, dusts, or vapors. Not only do we sell these cables, we also understand the application of them. For ATEX or IEC applications we offer instrumentation, control and power cables to BS/EN 50228-7, NEK 606, BS 6883, BS 5308, BS 5467 and many other. Cable Trays have been permitted in the hazardous (classified) locations in the National Electrical Code for Class I (flammable vapor and gases) since the 1978 NEC and have been used extensively in chemical plants, refineries, and other types of facilities. At a first glance, it seems to be simple and trivial but actually.
