Turns out the cable from the cupboard is actually on a 6A MCB which has no label on it. I have no idea what the 32A MCB "Immers Heater" is for now.

Garymo has a point, you can spur off a ring with 2.5mm2 with the ring having a 32A CB, why is it different for a radial?

Multimeter shows no voltage across any of the 3 sets of wires. I feel uneasy about just cutting them off and stuffing them back into the wall. Any advice? Also, with all 12 wires disconnected eveything works (lights, sockets etc). So definetly not lighting wiring. I had a closer look at...

Could it have been for a pump, or valve? If that is the case then none of these wires are actually connected to anything anymore, but all 3 wires vanish into the wall. I don't like the idea of leaving disconnected wires floating in the walls, how would you normally deal with this type of...

Nope, no confidence, wire just looks like lighting wiring. Considering this was the old heating system, your explanation sounds sensible. Given that, what would 3 sets of 3 core & earth be needed for in a central heating system. Now that the old boiler and immersion heater are gone, how can I...

Sorry, I mean 3 core & earth.

Well, the wiring in the old immersion heater cupboard is a nightmare!! It has the radial wire going into a switch with a wire that would have gone to the heater cut off. This switch then has a spur from it, going into a blanking plate with a fuse, which then goes into a 2G surface mount box with...

Thanks for your help.

Thanks Sparkwright. I will check the wire. But I assume it is correct as this was a new-build (Barrats) in 1995 and you'd like to think they'd get it right. If not I'll change the CB to a lower rating. After that, is what I propose safe? Thanks

Thanks for the reply Steve, I am probably wrong about the 2.5mm, the house was built in 1995 and this is the original wiring to the immersion heater that was in a cupboard in the hall (top floor, wiring coming down from loft). It is this wiring that I have found (it sitll goes to a switch in the...

Hi, I'm looking for some advice. I'm boarding my loft, we previously had the immersion heater removed and a combi-boiler fitted in a different location. I've found the old immersion heater wiring (single wire, not a ring) and I want to use it for a double socket in the loft. Am I right that I...
