Hi All
I'm putting a new kitchen in at my mum's house and have a couple of electrics questions:
1. There is an old unused FCU for an immersion heater that must have been removed when the combi boiler was installed. The wire looks like maybe 2.5mm² or 4mm² and has one leg that goes upstairs to the airing cupboard where the immersion heater would have been, and one leg that ends next to the fuse box (unconnected). Is there any reason why we couldn't get an electrician in to connect that wire up to the fuse box and use it for the oven? That would leave the leg that goes upstairs disconnected which is fine.
2. I want to add some sockets in the kitchen. The kitchen is currently supplied by an existing 2-gang socket on the ring main, plus a spur of two more 2-gang sockets. Can I just extend that spur with 2.5mm² cable, connecting into one socket and out to the next? I want to add one more 2-gang, and two 1-gang sockets (for general use, the hob sparker and the overhead extractor fan).
Rather than wiring from one socket to the next, could I do a star arrangement from a junction box to the end three sockets instead? I presume not, but I'm not sure why it would be a problem, other than perhaps for testing the circuit's resistance?
The total length of the spur is probably 6m, and the ring main is probably 5m in either direction back to the fuse box - it's not a huge house. The spur won't be for the oven, washer, dishwasher or microwave - that stuff is all elsewhere on the ring main.
3. Can the last leg of the spur be in 1.5mm² cable? That's already installed and although it's in conduit I'd rather not have to pull it out and re-do it. It's for the cooker extractor fan.
4. Can the cables be surface mounted behind the units? They're running vertically down the wall in chased out conduits, but under the units do they have to be in conduits or is surface mount ok? I can't fit conduit behind the units so it would have to go on the skirting board below.
Thanks!
Danny
