It's the part of the mini-hotel automation system project (SIEMENS to IOTON replacement).

I think I finished the main control enclosure wiring and test.

Totally I have 143 wires in it. 

Now it looks like this:

If you are wondered why the wires outside is so short and how to connect it in the building, I will try to explain it.

In the most cases cross panels with spring or screw terminals used for the connection between the control box and the equipment in buildings. On the picture below, cross panel for around 60 wires (I have twice more wires):

I chose another way. For high current connections I will use spring or screw terminals, but for the low current connections I will use RJ45 cross panel. I will pace it in another enclosure(for connections only) right below the main enclosure.  It will looks lite this:

This way to connect has some advantages, like savings on the wires, easy connection and space savings.
