Ring Main Joint Box

PG
A kitchen worktop twin S,O, is to be relocated horizontally by about 60cm. 

The ring final cct (RFC) is cabled in buried T&E and the galv' steel back-box is flushed into the plaster/brick wall.

The RFC T&E extension cabling will be buried under plaster, covered in plastic capping along the horizontal  prescribed zone. Visually, it would be reasonable for an electrician to be aware that the route may contain cable(s).

The circuit is RCD protected.

The intent is touse insulated crimp and double insulating tape the jointed cables within the existing box to achieve a maintenance free connection, A 2mm thick (fabricated) plate was to be used to cover the back box and provide additional mechanical protection. The box would then be plastered over.


The questions are:-

1. How many would consider the steel plate back box cover a desirable feature or would a simple plastic cover suffice?

2. Should the original back box be left  unearthed?


Thanks in advance.

    Become it will be blanked off and concealed with plaster leaving absolutely no indication of where the CABLE DROP to it comes down the wall to it.


    Therefore the cable drop is not in a permitted zone and it does not comply with the regulations.




    Eh? ?


    If you leave the socket in place, you keep the zones.


     




    Pay attention at the back of the class and read the question.


    The new sink is going where the existing socket is, that is why the socket is being moved.



    This is too complicated! ?
