Nicklas,

Do you really need a schematic of that cabinet or just a drawing of how it is wired?
If you don't need the "intelligence" of a schematic or a netlist of that cabinet, I would suggest using a 2D drawing editor and making a connection drawing (aka "Interconnect Diagram") of it rather than a schematic. I use QCAD for such drawings.

  1. I have discovered connections are usually marked with a number so number for net name seems like an obvious choice.
  2. There are cables and a bus seems like the obvious choice for cables, have not seens any numbers on these.
  3. As there usually are numbers on cable strands it would feel lik a good idea to enter this number in schematic, do anybody have a suggestion for suitable name?

Do anybody have any tutorial about how to make schematics for electrical cabinets?
