30a connector block, how can I tell

Pictures can be stuck OR screwed to the wall.

People fit pictures over unused sockets or blank plates.

Just clutching at straws so the op can get on really.

They can, indeed, but in the case of this mirror we have been told ...
.... the mirror company will stick the mirror to the wall.
If that means what it says (I accept that it may not) then that is definitely what I would call 'very inaccessible' :) (and I would say the same if it were a picture being 'stuck to the wall')

Kind Regards, John

What are we more concerned with?

Accessibility, or safe zones?

I can't speak for 'we' but, as I've said, I'm personally not at all concerned about 'safe zones' in this situation. My major (personal) concern would be about having any type of joint in cables (other, perhaps, than soldered) which is 'very inaccessible'.

But wagos (ok in their special boxes) ARE designed for inaccessible situations.

Perhaps the op should use a wago box instead of the blanking plate method, or remove the skirting board and try and push the wago box into the floor.

Quite why Wago specify their boxes must be used for inaccessible situations is beyond me - could be something to do with cable clamps - but how far do we go making a meal out of this?

I realise that, but it doesn't alter the fact that I wouldn't want them (or crimps, or screwed joints) in a 'very inaccessible' place. However, that's 'just me'.

I don't think it's Wago (and, anyway, it's not Wago who make WagoBoxes) but, rather BS5733 which, as you say, includes requirements for such things as cable restraint for a JB to qualify as 'maintenance free' ... not that I would personally want even 'Wagos in a WagoBox' in a 'very inaccessible' place :) (but, again, that's 'just me'!)

I'm not sure if a soldered joint is a guaranteed foolproof can-never-go-wrong solution.

I don't think that there can be such a thing as a "guaranteed foolproof can-never-go-wrong solution" (in this, or almost any other context!), but I am personally fairly confident that soldered (or, probably even better, brazed) joints are closer to that than are any of the alternatives. Don't forget that I have said that I would personally do all I could to avoid any joints in 'very inaccessible' situations, and that even includes soldered ones.

Having said that, I don't think that I have personally ever experienced failure of joints in any sort of JBs (the great majority of which have necessarily been 'screwed terminal' joints), even after many decades in-service. As for 'sprung' joints (Wagos, Hager/Ashley JBs etc.) I've yet to have long enough experience to know what their very-long-term reliability might be.

Not an ideal situation, having to bury a join, but it happens all the time, sometimes you can over stress it.

Since you can make that hole as big as you need, I would of used one of these 32 A Ashley MF junction boxes.

Box secures to the wall and good clamps on cable. Used these under floors.


Safe zones is one thing. I would be more concerned about verifying the circuit is healthy to start off with.
That the conductors are continuous, that its not already a spur. Zs, R2 and RCD times are acceptable, before connecting the spur.
But you need a meter !
Then retesting the same at the new socket. Making sure polarity is right. and values were as before, so you know your join is acceptable.

Only then would I be happy to see it buried. Half hour job for an electrician. Save you the worry

I wouldn't bother burying the joint to make it totally vissible until the mirror will cover it.

I'm with John all the way.
 
Got the skirting board off and seems a enough room for the box to go behind it

Just before I do anything else.
Thought I'd ask to see if the drywall box is in its best place? The Skirting board will be removable now to access if any problems. Would a junction box be better behind the skirting to connect the wires up?

What would be the best plan of action to deal with the wires feeding the original socket, just push them back down into the space where the floor is? fold them over on them selves or cut them shorter.


Actually now its i have access would the wago connection box

and these wago connectors be fine for the job?

Note that you can buy Wago connectors in packs of 10 from TLC

thanks I also had that webpage open and i ordered a few more bits for free delivery, sadly the wago box wouldnt fit in the space so i was hoping a conventional (circular) junction box would work

Oh how I wish I could make the same claim.
Noise of arcing in lighting JB's drove one family to distraction, they thought they had wasps in the loft but couldn't find them.
The worst that springs to my mind is a 45A on oven & hob, 3x 6mm² and 40A MCB, it was screwed to the wall behind kitchen units (inaccessible without cutting back of unit) and customer reckoned they'd smelt it from the moment the new kitchen was installed, fitters said it was the new oven and the smell would go away.

The damage to the neutral had affected the insulation to over a foot from the joint.
