Hoping someone might be able to help. I moved into my house just over a year ago and have since found some oddities with the electrics. The latest is the shed.
From switching off MCBs I've mapped out the circuits and it seems like the outside electrics (2 sheds and a couple of garden sockets plus lights) are fed from a 32A MCB it shares with the upstairs sockets, right hand kitchen sockets and cooker (gas). Only two 2.5mm t and e in the CU so guessing this is the ring final and looks to go upstairs first. There is SWA outside, coming into the outbuilding attached to the house. Here it seems to be fed from a single (guessing 2.5mm) t and e.
Two SWA cores (grey and black) are used for lighting. The feed to these goes through 5amp Fuse, shown, and another switch, not shown.
The other two feed all the outside sockets. The only protection seems to be the 32A MCB (and RCD). This doesn't seem safe to me. The load is unlikely to reach a dangerous level for the cable but knowing there is nothing stopping it exceeding the limit worries me. I am also having trouble finding where the spur is from. Any tips on finding this?
I am tempted to put in a little two way CU here. It would be simple and no doubt safer but is it notifiable and can this be completed DIY? I'm a railway signalling engineer by trade and we did a few months wiring domestic stuff (CU, rings, testing etc.). I am by no means an electrician but this seems a reasonable job to complete.
Any help much appreciated.
