Hi folks, We moved into this 2007-built house a few months ago and I'm trying to document the actual wiring, as opposed to what the labels on the CU claim. I've discovered something that I don't particularly like and would value your thoughts. I'm no spark, just a DIY-er. There's a 16A breaker in the CU labelled "boiler and garage door". There's two live wires connected into it. I had hoped this would be a ring. Upon closer inspection it's like this: Wire 1 (2.5mm t&e) goes to a socket into which the boiler is connected. Wire 2 (2.5mm t&e) goes to a double socket (currently unused), then another double socket (fridge and freezer) then another double socket (battery drill charging) then another double socket (currently unused). Effectively, spur after spur after spur. I didn't notice this initially, as I could see two cables running to all the sockets. I assumed this to be a ring but I now realise it's a chain. I'm less worried about the legality than I am about the safety. Is this setup an accident waiting to happen, or will the 16A breaker be a suitable safeguard against overloads and fire risks? Many thanks, Jim PS Updated in light of analysis. When disconnecting live wire from back of socket nearest the CU, the fridge/freezer still work but most other things do not.
