MICC replacement help

[Spunkywads26]

I've been given a job to rewire an upstairs flat and change the CU. I had a quick look around and everything is pretty straight forward except for the CU.

The existing CU is located in the small entry hall way at the bottom of the stairs leading up to the flat. It is mounted at high level opposite the front door. The meter is located in an external cupboard next to the front door. 16mm tails come from the meter into a henley block with MICC from the henley block to the CU.

I'm struggling to think of a solution to replace the MICC. Help. Please. Pretty Please.

Will the tails need to be burried in the wall <50mm? How far is the cable route from meter cabinet to CU?

Well the simple solution to replace the MICC is to replace it with,,, MICC.

Why does the existing need replacing?

I'd be curious as to how the MIMS has been connected into the ISCOs.

Are the conductors actually enclosed at the service terminal block.

Is the micc floating out of the block.? Why don't you just reterm into a metal clad s/fuse.

a pic would be nice of the services and cu.

Sorry the tails come from meter to the top of a metal ad box, then MICC comes from the bottom of the box and I assume it then goes underfloor as the MICC enters the CU from below.

My customer wants it replaced (Sub contract job).

best to leave alone and use what you got or get the jack hammer out !

 

[Spunkywads26]

Don't know really. Just said to rewire the flat and to put new tails in with a new CU.

what are the cables in the flat not micc?

 

[westward10]

Are you relocating the CU.

I am not understanding the reason for replacement.

 

[Leesparkykent]

I would be looking at replacing the whole lot back to the meter cabinet not the Henley block. Installing a distribution circuit if need be.

 

[westward10]

I am not understanding the reason for replacement.

I am guessing because it is surface fixed to the existing CU.

The op is changing the cu, so it will be straight forward, metal clad cu, existing MICC bushed up from the bottom, can't see a problem with that Westie.

I suspect the client does not like the aesthetics of the surface cable assuming that is how it is fitted.
