Hi
Just some background, I fast-tracked into being an electrician a few years ago and doing ok, however, the practical options for the following has been the interesting bit. Grateful for any thoughts...
Scenario:
Customer has an external flush meter box on the side of an attached garage. CU is internal about 1m above external meter. Supply is TNS, 80A
Customer is converting garage to a dining room and extending upwards and to the rear with a kitchen. CU to be moved to the kitchen (still on the same wall as the meter box). This will mean a horizontal distance of about 8 metres.
Question is how to extend the tails from the meter box to the new CU ( FYI: Customer does not want to have SWA on the outside and no obvious electrical hardware etc in the dining room) .
I appreciate when it comes to costs and practicality it may be external SWA but until then.....
My thoughts so far for a viable option????
1) Run the existing tails into a new external box (sitting above the current meter box) with a fused (60A) isolator
2) Using Split Concentric Cable (25mm CSA for L,N&E), Run horizontally out the rear into 25mm steel conduit and up a chase on the the inside wall. I would also have a double socket placed below the vertical chase as a belt and braces approach to prevent damage i.e the chase will then also be in a valid zone.
3) Run the Split Concentric Cable out from the wall into the new ceiling joists , through the joists to the kitchen area.
4) In the new kitchen area, run down the wall in 25mm steel conduit and terminate in new CU.
So, opening myself up to any constructive thoughts...
Thanks in advance.

- Does this seem a practical approach?
- I haven't used Split Concentric Cable but I understand it will run in 25mm conduit however terminating can be interesting? Thoughts?
- I need a small external recessed box to house the fused isolator but cannot find a smaller one other than a meter box) (local wholesalers drew a blank)?
Thanks in advance.
