Sometimes called switchboard mats, these nonconductive mats protect against shock by preventing the worker from being grounded if an electrical discharge occurs. These mats are used in high-voltage areas where electrical fuse boxes, transformers, or high-voltage boxes are placed. Whether in a distribution room or an electrical repair site, it will provide you with reliable protection Multi-size : Thickness --- Maximum Voltage:. Temporary power on construction sites is essential, messy, and potentially dangerous. Pairing E-abel distribution boxes with Weipu industrial waterproof plugs creates a rugged, IP67-rated temporary electrical solution that resists weather, prevents accidental contact, simplifies field wiring, and. Rubber insulating blankets and matting provide a protective layer against electrical current and are ideal for use by electrical utility workers, power and communication linemen, electrical contractors, electrical field service technicians, telecommunications companies, cable television operators. See Out-of-arm's reach or interposition of obstacles. These measures are used only in low-power circuits, and in particular circumstances as described in Extra Low Voltage (ELV).
