Can i run a spur from an immersions fcu

[mancduff]

thanks securepark can i then from the double pole, spur 2.5 coz i have to chase it and that would be a pain with 4mm by the way the manufacturer recommends 3Amp fcu so its not pulling that much power. Yes jb is 30 amps.

I still don't know what size the protective device is?

Until then I can't say.

However, I would be tempted to use the same size, pain or not. Sorry!!

mcb is 20amps its feeding one socket not in use and a hoover washing machine the cabling to the unused socket is 4mm the cabling to the socket that runs the washing machine is 2.5mm, don't ask why i wasn't here when the kitchen was rewired - where i am up to now, ive broken into 4mm with 30amp junction box link to pic of which is in my earlier post and was planning on running 2.5 off it if i can't which is what seems to be the general consensus can i run it from the 3amp fused fcu as the powershower won't except any cabling bigger than 2.5mm if any of this is unsafer than running a spur from the immersion heater fcu i will run it from the immersion fcu instead. Any thoughts - thanks in advance

just found out now that the cabling i thought was 4mm is actually 6mm i don't know what the spark was thinking using that size cabling for a socket, so can i or can't i run 2.5 off it to an fcu or from the fcu to an 3amp powershowerunit.
