Rubber Power Distribution Boxes Featuring Switch Rated Plugs and Receptacles


Meltric Corporation a manufacturer of UL switch rated plugs and receptacles is pleased to introduce a new line of portable power distribution boxes that are made of a durable rubber material. The heavy-duty rubber boxes provide portability while the switch rated plugs and receptacles ensure electrical safety and simplify code compliance. Standard as well as custom configurations are available with inputs up to 100 amps and voltages up to 600 volts. Optional features include mini circuit breakers and duplex receptacles. With the release of this new product line more facilities will be able to benefit from using Meltric’s switch rated plugs and receptacles to distribute power to welders, lighting, pumps and other electrical equipment. Meltric’s switch rated plugs and receptacles protect workers by preventing exposure to arc flash and live parts. They feature an integral switching mechanism that ensures the safe make or break of live connections and makes certain that the contacts are dead before the plug can be removed. They are UL approved for use as a ‘motor circuit disconnect switch’ and as a ‘branch circuit disconnect switch’. Safety is also assured when re-inserting the plug into the receptacle because the male contacts do not engage the live female contacts until after they are fully enclosed inside the device’s arc chambers, thus preventing outside exposure to arc flash. Meltric receptacles feature a safety shutter that ensures user safety by preventing unintentional finger, tool or wire access to live parts. By preventing worker exposure to live parts the safety shutter is able to maintain an electrically safe work environment as required in the NFPA 70E Standard for Electrical Safety in the Workplace. Since a NFPA 70E defined hazard/risk category of zero is sustained during equipment connection and disconnection, a qualified technician does not have to wear PPE nor follow other cumbersome NFPA 70E specified safety procedures that are typically necessary for electrical safety during change-outs of hard wired equipment or equipment connected with pin and sleeve devices.
