Explosion proof boxes, often referred to as Ex d in the industry, are used in hazardous locations. They are designed to withstand an internal explosion and prevent the ignition of an external explosive atmosphere....

Rigid metal conduit (RMC) is sometimes used as a wireway in hazardous locations. Where RMC is joined together, a union is used. This union section must be wrench tightened to provide electrical conductivity if the conduit is likely to be come energized due to internal wires shorting to the...

Leakage currents from power supplies, undetectable by human touch, can be enough to ignite certain explosive atmospheres. Therefore, intrinsically safe (IS) barriers must be isolated from the “dirty ground” and connected to a “clean ground”. This starts at the mounting (DIN) rail of the barrier and continues all the way...
