The general concept for my electrical installation is that I can access any cable, connection or any electrical component easily without removing half of the cabinets. One aspect which needs a bit more attention to hide the cables are the slide-outs. Cables can only come into a slide-out close to the inside corner and one needs to leave enough length of all cables that they are long enough when the slide-out comes in but also fold out of sight when the slide-out goes out. Each of the slide-outs requires a slightly different approach to achieve this. The cabinet to the left of the work area is recessed a bit and it does not reach the inside edge. The reason for that is that I have a bit more space when sitting down or getting up from the chair and allowing the knees to clear the cabinet when turning on the chair. This is the reason it is not straight forward to bring in the cable into the slide-out. I decided to use the following approach.
I will place a cable channel in the left outer corner of the slide-out and run the cable up to the blind pelmet. The pelmet is extended on both sidewalls and will cover the cables on the left side all the way to the inside edge. I also use the pelmet to cover the indirect lighting and made it the same on both sides.
The cable channel is covered with a panel sitting against two triangular supports. I use clips to fix the panel and make it removable.
The hole in the shelf and the support for the cover panel.
The image below shows the pelmet extension on the left wall of the slide-out. Not painted yet and no trim.
The image above shows the cover panel sitting in the corner. Also not painted yet and without trim. The pelmets are removable, not glued.
I glue an angle to the panel and fit the pelmet with screws. I made a few dozen of these angles. The panel shown above is the pelmet for the small blind in the kitchen.
I also fitted the pelmet for the large blind in the kitchen and painted it. Will take a pic when the trim is on. May have to paint it again.
I also installed the main 12V cable from the battery compartment to the distribution point, then to the fridge enclosure where the smaller inverter is going to be fitted and the all the way into the bedroom, where the cable will run down the wall and into the lower section of the TV cabinet where most the electronics are installed and from where most of the 12V supply cables originate. I use 00B&S to the distribution point and then 0 B&S. The distribution point is behind the control hatch on the left, where all the other 12V chassis devices are connected to including the brake actuator and ABS unit.
