tingle from bare wires when off at mains

[Erie Fred]

Let's not forget any insurance claims might be null & void, especially with an internet search of this conversation.

Just because you've switched that circuit off it could well be connected to another still live one.

Buy yourself a cheap multimeter from Screwfix etc and you can do some basic testing.

I think we've established that an actual electrician is required, or someone with An Elfin Clue regarding electrical safety... As it is, it's beyond "potentially" lethal, it's a death waiting to happen.

that passed a EIRC has it

 

[Morrisman]

There's so much corrosion going on the system is producing it's own current, like dissimilar metals do when wrapped together.

I've asked enough electrical questions on here and been guided through my issues by a few of the experienced members who know what they are talking about. But... in doing so, I have also learnt (and had to respect) that when they say 'that really needs a professional to look at it' that it errrr really needs a pro to look at it...

If I had to work in that building I would spend a couple of hundred quid and a weekend. Rip out everything back to the incoming, new consumer unit, new wires, new sockets all round.

I agree, its also often easier to start from scratch and get it right, than fix other bodges

 

[dobbslc]

Just wanted to know if it was possible for wires to have 'current' lingering in them.

No.

The brown is on the incoming unswitched live,

I didn't spot that!
Mmmm, switching off the main isolator here will potentially (probably since you're getting shocks) leave the load on that armoured cable looking for a return path when it's neutral is lost, it'll find the path of least resistance to do that, probably the earthing system or you !
What are you actually getting the shocks from?

 

[brightspark]

what dick has put the armoured cable in presumably a submains being conected to the main feed supply to the db. black has been conected to the output on that db the neutral and all the outgoing neutrals conected on the input to db so even with the breakers turned off the live brown on the armoured is still live and your getting a return back feed on the black nerutral feeding the outputs that are in wrong place its easy to see whats going on

 

[brightspark]

its looking rather strange only 3 red output cables and 7 neutrals that realy needs investigating properly by someone who knows its askin for it just messing on with that. it needs rcd protection as well

Is that like an EICR?

my middle finger is too quick!

That's not 7 neutrals on the black incomer to the isolator, that's the neutral outer to a concentric cable - which consists of a large red central core and multiple black outer strands. As far as I can see there's only four outgoing neutrals on the terminal block beneath, lights, socket ring (x2), and the miscreant armoured cable black.

concentic shouldnt be used to supply a db

 

[Hopefuldave]

Anyone think of any more dangerously broken Wiring Regs we've missed? Only seen one socket and the fusebox so far, I suppose... Plenty more to come!

[drjim]

My advice to OP is to get a proper sparky in to sort it out. Looks scary even when seen over the internet!

I was afraid to touch my screen... Kept one hand in my pocket when I had to.

Not any more it shouldn't, but it used to be common practice. Split concentric too, which this probably is, with a few earth strands alongside the neutrals. Seen it regularly in farm setups and as flat submains.

Very sensible advice.

 

[knighty]

as long as access is ok it's not really a bit job to rip that out and start again as long as access is ok?

fust box is all top entry so move it up a foot to give you a bit of extra lenfgth when youre stripping cables back

I know some people don't like it but I'd buy a length of 4mm SY cable and wall mount it, run it as a spur to all ther sockets behind a 32amp fuse

could be a good chance to upgrade the lights too

maybe offer to get it sorted in exchange for some rent free months?
