A support rail for luminaires or electrical units, having:
- a support rail profile, which encloses an elongated receiving space:
- a plurality of conductors running in a longitudinal direction within the support rail profile;
- two busbars arranged in the receiving space, and each busbar having an insulated structure with longitudinal grooves that holds each of the conductors separately;
- an incoming supply element mounted to the support rail profile and having contact terminals and connection elements to form electrical connections between the conductors held in the busbars and external cables leading to power supply units or communication or data transfer units, wherein contact terminals and busbars dedicated to power supply including phase selection and ground or neutral are permanently assigned, and other contact terminals and busbars are flexibly assigned in terms of function;
- display means on the outside of the support rail profile for visually representing the function of the conductors, wherein the display means for the power supply terminals are not modifiable and the display means for the flexibly assigned contact terminals and busbars are modifiable.
