Consumer unit to be moved away from service head

[Chris]

Hi everyone.
I have been asked to relocate a consumer unit from a cupboard outside a house into the inside of the property. The main fuse and meter will be remaining outside however the run is about 6/7 metres long, i believe it states in BS7671 that the meter tails cannot exceed 3m in length.
would this require me to put a separate fused connection unit within the 3m of isolater and then run a 25mm SWA + 16mm earthing conductor from the fused connection unit, to the 6/7m away consumer unit location? If not who knows a better way?
thanks, chris.

Yep, bung in a fused isolator mate.

Newbie question if I can,would a time delayed rcd comply in that instance?

How far advanced are you in your career Chris, only to answer your question with any clarity it would help if we knew what your experiences are and what qualifications you hold, your profile throws up an error message.

What is the route from head/switch fuse to new location?

It will be along the outside wall of the house which will be rendered over.

Does the maximum demand require 25mm or could you get away with 16mm?

Are you on a TT?

 

[Baddegg]

Tns, but the consumer unit has been moved by someone before we bought the place as the original tails go into the rcd I mentioned earlier then leave the rcd in armoured and go to the unit under the stairs,

 

[Baddegg]

Apologies if I’ve hijacked your thread chris

Your really starting to annoy me, why do you always insist on taking threads of track. If your reply doesnt fall within the OP's question dont bother!

Then I cannot see why that RCD has been installed.
