Hi, we have been asked to relocate a consumer unit however the meter cupboard will be on an outside wall 7m away from the consumer unit, the main switch is under 80amp, im just wanting some opinions on the way to overcome this, am I right in thinking I could run 16mm swa from the consumer unit, cleated to an outside wall, running to an adaptable weatherproof box situated next to the meter cupboard, then using Henley connector blocks, i could connect the swa to the tails coming from the meter box.
 
That makes things a lot easier then..
What is going where the old cu is located?
Can the isolator go there?
Its a temporary thing at the moment, the meter is being moved friday but for now until a few months down the line the cu is staying where it is, then eventually it will moved behind the meter cupboard, so really for now I need to connect the exsisting cu to the new mrter cupboard
 
So can you put an isolator (fused) behind the meter cupboard?
Then go from there in swa to cu
 
The meter boxes have knockouts in the bottom that can be reinstated later on..
I would come out of the bottom in trunking and then go bottom entry into an enclosure with the isolator inside.
We’re supposed to use designated entry points in the meter boxes

the dno will be coming tomorrow but im not sure if they will use a 100amp with 25mm tails or an 80amp, its more likely going to be a 100amp switch but as the job is temporary and the house load will not even exceed 80 amps let alone 100amps do you think it would be fine to connect a 16mm cable from the meter to the vonsumer unit even if the dno use 25mm tails or shall I use a 25mm cable too
 
Obviously once the job gets going in a few months i will upgrade the tails to 25mm once we move the consumer unit closer to the meter
 
That would make sense yes! Am I right in saying by using 16mm swa cable the fused isolator will be an 80amp fused switch?

No you are approaching this incorrectly, you don't pick a cable size then work backwards to the fuse size. You need to establish the design load and then work through the calculations to establish the correct fuse size then the cable size.
