First a minor correction - that should have read a CTEK charger. Secondly, you may have a different distribution box to mine - you mention a 15A fuse - mine has got 2x10 and 1x7.5 amp. However, the process will be the same.
Obviously, don't have any power connected. Remove the cover from the box. Find where the mains feed enters the box - mine was at the top. Trace the feed to where it is connected to the transformer, and disconnect - if necessary making the feed-in cables electrically safe. You could also disconnect the output wires from the transformer. So that is the transformer out of the system, whilst leaving the 240v RCD and MCBs intact. In my case, I already had the 12v feed from the battery coming in to the feed side of the 12v fuses, so that is all I had to do - apart from replacing the cover!!
The battery I put in years ago - I built a small plywood 'shelf' under the wardrobe behind the gas fire. Built it so I the battery is held in place by a couple of bungie cords. The CTEK charger I screwed to the wall above the Hobby electric box - see photos.
First photo shows mass of cables behind fire. I also cut a hole in side of van and covered with a grill to aid air circulation - this cannot be seen as it is 'behind' battery in pic.
Second pic shows the charger screwed to the wall The big blue box is the electronics for the mover. You can also see a 240v socket bottom left - I had already installed this for something else (a rechargeable hand vacuum cleaner), but when I put the charger in, rather than hard-wire it in I just plugged it in (the cleaner had long since died!!). The switch you can see is between the battery and the 12v fuses, so for travelling, I can turn the 12v systems off. It is actually a double pole switch so it is switching both the positive and -ve. [NB I've had to keep spelling out 'positive' as this website doesn't like the plus sign!!]
As your fuse holders have disintegrated, you will need to get something like these:
Just enter "in line fuse" in ebay.
Simply install one of these, with the correctly rated fuse, between the 12v positive feed from battery/charger (ie from that switch) and each 12v circuit. There is probably a -ve bus that all the 12v circuits return to - simply connect the -ve wire from the switch to this bus.
If anything not clear or you want further info, let me know.
EDIT (after seeing Jeff's comment). When I bought my charger, I got it on-line, far cheaper than any caravan shop around my area. I think it was Amazon, but shop around.
