Decade Flash: Belt

If you meant something else (e.g., a fashion accessory or a specific product brand), please clarify. Otherwise, the following information addresses the standard technical and safety application. A Decade Flash Belt is a high-voltage, portable temporary protective ground set used by electrical utility workers. Its name comes from its design purpose: to withstand the thermal energy (arc flash) released during a fault for a period measured in decades of cycles (e.g., 30, 60, or 90 cycles of a 60 Hz system — meaning 0.5 to 1.5 seconds). It is also called a "decade-rated" ground set or arc flash protection belt .
