Electrical distribution arrangement in explosive environment

The arrangement has grouped T-shaped elements, each with a plug-in contact device with contact pin and complementary socket, each pin connected to a contact socket via a bus bar wire, and with counter plug-in contact devices on the branching arm ends with contact sockets connected to the bus bar via a 4-pole. Distribution elements are arranged to form breakdown-proof gaps between contact pins and first counter contact device shafts. The arrangement has grouped distribution elements (2) of essentially T-shaped structure, each with a plug-in contact device (6) with a contact pin (61) and a complementary socket (71), whereby each contact pin is connected to a contact socket via a wire of the bus bar (4), and with counter plug-in contact devices (8) on the branching arm ends whose contact sockets (81) are connected to the bus bar via a 4-pole (5). The distribution elements are arranged along the continuous arms to form breakdown-proof gaps between the contact pins and the shafts (73) of the first counter contact device.
