Extension - ATTIC - Stage 2. The Execution

Now, when the wires are laid out and all is prepared for the final crossing I can declare that electricity is easy.  It took us (an electrician and me) 3 days of work (8h each).  The most difficult part is drilling holes in the traditional bricks and mounting the electrical boxes.  Doing the same in YTONG walls is a piece of cake.

As to how and what has been done - the setup is as in the rest of my house.  All the wires are pulled down to the floor.  All wires are concentrated into bundles and a broad 'river' leads to the junction cabinet.  The sockets are powered with a YDYp 3x2.5 wires.  The wall switches with UTP.  The lights with YDYp 3x1.5.  The Blinds with YDYp 4x1.5.

A few words about the junction cabinet.  I expect to fit there the electrical protection modules, relays and LSA (KRONE) modules. The PLC stays in the basement in the main cabinet.  I have considered the need for using a 2nd PLC to have a redundancy, but I ended up deciding that it would be too much.  I laid down a thick bundle of 12 UTP wires from the basement to the attic level for future communication.  "Communication" is too big a word for what we need.  It is just about sending simple impulses.

I have searched for a way to mount the KRONE modules in the cabinet. Back in the basement I invested a lot of time into cutting a piece of metal and drilling holes.  This time I decided to attach the KRONE modules directly to the DIN rails.  A photo below shows how it was done.

I chose the ABB 96 module U42 cabinet.  It surprised me positively with its high quality and what was inside.  No shortcuts.  A stable construction and a set of handy plug-in boards for neutral and protection wires. 

If this is the first time you see such a cabinet you might be confused by the number of wires.  Do not worry.  What you see is a 'light' version.  It is just for 3 rooms, a bathroom and a lobby.  A full house has external lights, door bells, more rooms, and the kitchen.  They make up for a big portion of additional wires.

The plan for the components in the cabinet is as follows: The lowest level for the LSA modules.  The relays 1 level higher.  Then the electrical protections.  The top level as a reserve for the switch or any additional devices.

It might be that I am slightly skewed, but wiring a cabinet is a pure pleasure for me. I let's me unwind and gives a lot of satisfaction.  I am happy when I can arrange it all from scratch and make a new order.

The photos below show the stages of my work.

The 3rd photo shows clearly that the cabinet could be much smaller for the needs.  In fact I use only a half of the available space.  The error in my calculation came from the expectation that the recuperator will need a 3-phase power.  That would mean a larger switch and a 7-module wide power meter.  I ended up with a single-phase B16 protection and 1-module with meter.  At the end of the day I am not worried about the redundant space.  During the last 6 years I have added a numerous bits and pieces to the main cabinet and all the extra space found some use.

So, how does it all work?  Great!  I needed a few minutes to modify the code and here it is!  My attic has become a part of the rest of my 'intelligent' installation.
