Requirements for cable trays in explosive atmospheres
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. 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. This article is about code requirements. Let's break down what you need to know about explosion-proof requirements for cable trays in these environments, keeping it simple and clear.
