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.

    Bye heck! This is like drawing hens teeth.


    From the new box the cable will run 600 mm horizontally, then it will join the original drop from the ceiling.


    If someone decides to put a shelf up above the sink how will they know where the original drop comes down the wall with the original socket location having been concealed?


    It doesn’t comply with the regulations.
