Relocation of kitchen so let etc

Forgot to mention that the circuit is protected by an RCD so I'm thinking that even the last option is viable since the wago connectors should be maintenance free and the buried cable is protected via the RCD.

Will the terminals be in a safe zone, in a maintenance free enclosure, and will they be safe from the customer drilling there in the future?

If so, there isnt a lot of difference between joining cables in a maintenance free box, and a buried straight cable run, so I would consider doing it unless there wasnt any other way of removing the cable.

Strictly speaking you need an entire MF marked junction box to form a maintenance free connection - wagos alone in some other enclosure don't meet the specification. Arguably you could do something equivalent (but on your own head be it) - but beware that wago terminals etc are normally de-rated when used for MF purposes.


If the kitchen is being re-fitted and there's going to be a plasterer in anyway, wouldn't it be possible just to replace/re-locate the cable run anyway and so design-out the problem?

The joint has been made in where the 1st RFC outlet was, the client has what looks like a work surface in place where you would normally find a tile splashback. 

The kitchen fitter has cut a 2G gang hole thinking that there will be an outlet here when I'd already told him to just board over the back box (tested RFC of course) he's now telling the client that he has concerns over just covering the live cable which are terminated in Wago connections. The joint would have been 200mm above the sink location so I don't think I know of anyone that normally starts to drill in that location.

Still nothing to say the cables where there if he'd just covered over the box is there though? At a minimum there should be a blank plate if its not in a prescribed zone

or behind earthed metal, armoured, more than 50mm deep from the finished front, or installed prior to 1989..

Thanks for all the replies guys. 

I'm going to cut out some glav trunking lid and screw in place over the 2G and 1G back boxes has required before they get over boarded. Have taken photo of prior to making good and will include this with the rest of the documentation. The existing cable is already protected by steel capping and a upfront RCD. The plate will give a similar degree of protection has the capping. So should be sufficient along with all the other measures.

So in years to come when a kitchen fitter drills through that capping and through those cables, that no one knew were there, its ok because there is RCD protection? Capping is protection from plasterers trowel and containment, a drill will blast through that. Not really an acceptable way to leave it in my opinion, pictures or not

Dbat, maybe not in your opinion. 

all joints which there are two off are all within safe zones. The actual joint is having a steel plate over to cap over the 2G backbox with a splashback MDF type panel over this. The other joint is at high level again in a safe zone which is getting covered in a similar manner. All documents will be produced along with photographic evidence outlining Cable routes and joints. I'm satisfied that I've provided enough protection and documentation including client handover and importance of keeping electrical file in a safe place for any future owner. Btw I've come across alot worse myself but agree that standards should be held to a high standard where ever possible.
