sub main to consumer unit on new builds

[Phil mcp]

Hi. I have a small new build sit to price up. The consumer units are to be sited in the middle of the house behind the front door. After best way to supply from external meter box. I was thinking of using split concentric from kmf with a metal plate over it on internal walls. surface mounting or trunking not an option.

Nearly always see 16mm swa used in these situations run through the building and on an 80amp fused switch

Swa for me. Mainly because i hate split concentric

Mainly because i hate split concentric

Any particular reason?

Any particular reason?

I fitted hundreds and hundreds of street lighting columns which had 16mm split concentric specced over the course of a couple of years, cold hands, small cutouts and 2 or sometimes 3 16mm split cons ruined it for me

I think this is a -----up between the convenience / size of a KMF with the PITA factor of having to add your own mechanical protection, versus a larger switched fuse and the convenience of SWA?
It would be nice if there was a larger shroud for a KMF that was big enough to terminate SWA within.

EDIT Oh wow the word T0SS is blocked....

Only problem with swa is terminating in to consumer unit rear entry.

I have made it off in a galv through box, shove this back in the wall and bring the inner cable through the back of the new board

As above make it off in a conduit box and bring your cables in from there
