Grounding of Industrial Distribution Boxes
26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. Grounding is a mechanism to protect distribution equipment and people under normal operating conditions, abnormal operational (overcurrent and overvoltage) responses, and hazardous conditions such as shocks. Few topics generate as much controversy and argument as that of grounding (or earthing as it is called in some countries) and the associated topics of lightning and surge protection of electrical and electronic systems. During the manufacturing process, metal enclosures typically have fixed points welded to the base plate or side walls. Solidly grounded systems create fatal and costly arc-flash hazards that cause substantial damage at the fault location. When lightning strikes or a rogue voltage surge decides to crash the party, proper grounding steps in like a seasoned bouncer, redirecting danger away from.
