30A 240V General Electric Spectra Series Busway Plug. Instead of running wire the entire distance throughout the factory floor, busway systems enable all the power to run down the bus and Bus Plugs are used to drop power to any specific location/machine along the way without having run wire for every machine individually. Using cable also suffers from power drop, where busway has minimum power drop. Motors run stronger and cooler. SB321RG is a switch operated fusible plug.
