Any electricians out there? need some help
Fuse for the down stairs plugs popped during the night.
Assumed something has died and unplugged everything (literally out the wall) turned it back on and pop it goes again ..
Help? I have no idea what else to do now?

Every single plug attached to that circuit is unplugged and the switch off. It's my downstairs all upstairs plugs have been tested and are working, no faulty devices, on the off chance it's been wired wrong.
If the power was staying on, no device would have power, the cooker has it's own circuit and is working fine, but is also off.

I had a similar problem,
Fuse blowing but no devices attached (as far as I could tell)
So I had to do some thinking and proper PD-ing
It looked like it was a junction box - and when I opened it a gooey mess came out
A spider had obviously crawled in and inadvertently made a connection between the live and neutral - for a short time the we spider had become part of the national grid
Cleaned out the goo (which was still making a connection) and all good

Im no sparky .but from experience at work (in a school) the mcb do tend to not be up to yje job after a few years service. I make it a general rule that if it trips twice , theres either a faulty mcb or there is a prblem other than old age. We have had them go bad after just 3 or 4 years in use

call a sparks or find a insulation resistance tester to test the cables if you are 100% sure there is nothing left connected on the ring main,
or just swap the cables from 1 ring main to the mcb for another to test that,
if they are on the same side of the board then it`s just a case of swapping the lives from mcb one to another.

Is it a rewireable fuse a mcb or an rcd that is tripping.Just noticed you have no outside lights so i would go for these first as possibly being the problem.

Wiring is pretty straight forward to diagnose, if you have a decent multi meter.
most of it can be done from fuse/consumer board
Identify is it wiring or appliance fault, I am assuming wiring fault
Turn off main switch to fuse board.
Identify then isolate the faulty circuit, (remove live wires from circuit breaker.)
Measure first short/leakage between live and neutral, there should be no leakage or short.
Measure between the two Brown wires for continuity on ring circuit, there should be.
measure for continuity between earth and neutral, there should be
finally measure continuity of neutral wires by disconnecting these from circuit.
The difficult/boring bit is then going around checking each point to find problem.

If the outside lights are fed on the same circuit as the ring I'd say without seeing it they probably shouldn't be unless fused down etc, and not a spur off a spur??! And judging by the weather is where I would be looking first off at the outside lights forwater ingress.
Don't try fault finding with a multimeter it won't get you anywhere....
If you have unplugged and isolated/switched off all equipment and it still trips it is a wiring/accesory fault, is it a fuse, mcb or rcd going? It will make a difference as they all trip for different reasons, is it a main rcd or individual rcds?
No need to start taking anything apart just yet until we get to the bottom ofyour set up. Pm me your number and I'll call to talk you through it

I apologise for my error but when it was said that there were no outside lights i took it that he meant that they were not working either and as for jumping in with crap i am a fully qualified electrician.

Until the OP clarifies his set up its irrelevant all the advice anyways!
I would also suggest that non intrusive fault finding is advised as. The OP has already suggested his electrical knowledge isn't 100% s

Thanks and maybe Ooperbum is aptly named.
