I've recently moved into a 1970s house and we have an old 6 way Wylex CU with fuse wire, but the wiring itself is the grey plastic covered type. I am considering improving the safety of the installation with MCBs and/ or RCD protection.
The 6 circuits are: cooker, downstairs ring, upstairs ring, garage (radial), upstairs lights, downstairs lights.
My understandings, and where I am seeking confirmation, is that RCD protection would be best for the garage circuit, and parts of the downstairs ring where I might plug in items I use outdoors (like a lawnmover).
I had thought about a new split load CU, but there are areas of the downstairs ring where I understand I would not want RCD protection - study containing my PC, the kitchen - contains fridge, freezer, washing machine. To overcome this would require splitting the downstairs ring, which sounds expensive in terms of time, effort and cost.
So the solution I wanted to sense check was to get an additional garage CU with RCD - this would be inserted into the exisitng radial circuit, and replace 2 sockets at the front & rear of the house where we use the lawnmover with sockets that have permanent RCD protection. On the original CU, I would also replace the fuses with plug-in MCBs.
Is this a reasonable plan or is there something wrong with it?
