So the leccy trips out today forcing me to do some investigating. I knew the pond for the socket was wired in 0.75mm2 flex off the back of a socket and had been meaning to disconnect it for some time, so took the opportunity to do so, and the power tripping off was solved.
What I wasn't expecting however was the socket to also be wired in
0.75mm2 flex! We had our fridge and tumble drier plugged into that socket!Some more prodding reveals one side of our kitcken wired as in the diagram (see the link).
a 3KW kettle, 3KW tumble drier, 1KW toaster, 800W microwave, 250W of lighting, and a fridge all connected off one 2.5mm2 spur. Eeek!
I've disconnected all the 0.75mm2 flex. How would you fix the rest as you are only allowed one single or double socket on a spur.
Only way I can see is to run wire from the last FCU up to the ceiling above, hopefully find where the circuit descends to the socket on the ring and make it a ring again. This would be a right PITA as are floors are chipboard (but might give me an excuse to fix where the floor is uneven in the spare room due to being carved up for what looks like installation of the central heating).
I Thought about putting the spur on a FCU but I think the load is probably too much for a 13A fuse.
I Traced the earth leak to the UV lamp for the pond, so no worries there.
P.S.
The new PCB got our boiler going again thank the lord. Bill came to =A3454 so not as bad as I thought it could have ended up being but still very ouchy.
