Power supply system for groups of electrical loads

A power supply system for groups of loads, comprising:

• at least two segments of the group of loads, wherein each segment includes:
• a first end region, a second end region, and at least one electrical energy-consuming device, wherein the electrical energy-consuming device is fed with electrical energy by the power supply system;
• at least two connection devices which are arranged along the first end region and at least two connection devices which are arranged along the second end region, wherein each connection device includes at least three terminals for removably holding a respective electrical connector, and wherein the electrical connectors are connected to a respective end of one of a plurality of electrical conductors, and
• wherein the terminals of the connection devices are designed with a same structure such that the electrical connectors with a same structure are used both to connect the connection devices within each segment of the at least two segments of the group of loads and to connect the at least two segments of the group of loads together.
