Socket on 1mm cable

[jonny_throstle]

Hello,

I had my boiler replaced (and relocated) a few months ago and the old one removed but the cable (1mm) for the old immersion heater is sill in place, connected to a timer on the wall, and running back to a 15amp ceramic fuse in my wylex consumer unit.

I want to redecorate the bedroom where the old boiler was, and remove the timer, but i don't know what to do with this cable.

Would it be a bad idea to replace the timer with a mains socket ? or is the cable under-rated for that ? or what about a fused socket ?

I'm not confident enough to remove the cable from the consumer unit. I could leave the fuse out of the CU but i'm worried in case someone plugs one back in !

Any suggestions ?

Are you sure it's 1mm?

15amp Immersion circuits are usually run in 2.5mm

Its been marked up inside the wylex face plate as "immersion 1mm" but i must admit i didn't check the cable itself because I can only see the 3 single wires and i havn't got anything to measure them with yet.

So if it is 2.5 I guess it would be ok to change it for a socket ?
what if it really is 1mm ?
