Consumer unit replacement

[Mikey10695]

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.

Bear in mind any requirements for fusing.

I will keep that in mind, but would you agree with the procedure I stated?

Is the meter box surface or flush?

 

[Grant webber]

I would go metre to switch fuse. Then swa from switch fuse to cu

Theyre installing it friday but im pretty sure its surface

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

That would make sense yes! Am I right in saying by using 16mm swa cable the fused isolator will be an 80amp fused switch?

I will have to see the situation behind the meter cupboard, the other alternative would be to mount an adaptable box next to the cupboard as an enclosure for the fused switch

I would go for 63 amp tbf

That was going to be my other suggestion but you will need to go bottom entry into the meter box

Okay I appreciate the help do you not think if I surfsce mount the adaptable box I could drill a 20mm hole out the side of the meter cupboard and connect via conduit to the adaptable box?

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
