Multiple connector system with several outlet sockets - has groups of three sockets connected through cable to three-phase plug with neutral and earth contacts

摘要

There are several outlet sockets which are connected by a cable to a plug. The plug is a four-pin or five-pin three-phase plug (10). The plug system is connected through a four-core or five-core cable to at least one group of three single phase outlets (20r, 20s, 20t). Their phase contacts (p) are individually connected to the phase conductors (13-15), while their neutral and earth contacts (n, s) are joined together (13, 17). The single phase outlets may be two-pin sockets.
