New Build. Consumer Unit 7 mtrs from Supply Box Installation Advice Required

[GHDirect]

Hi all
I am retired but needed a project so self building our new bungalow on an existing plot with power.
I have Part P but limited experience on a totally new supply installation.

The main supply and meters will be into my new white box on outside wall at 100amp and this has been agreed with Western Power.

My consumer unit is approx 7 mtr away in a cupboard within the new build.

The property design has a concrete block & beam floor which once laid is not accessible so I need to ensure I install any channel or duct prior to thread cable through later in build.


Earth will be a new spike and I will install this near the box to take a 16mm earth cable into the build.

I'll need an 80amp fuse within supply box for my feed.

I need to install a duct or conduit under the floor to thread supply cable.

1/ Should this be plastic or metal?

2/ Should I use SWA or just shielded cable within the duct or conduit?

3/ What size cable for 100/80 amp supply is recommended?



Regards

He was a massive jobs worth. Simply refused to connect to the switch fuse.........

As i said previously, next time either get the guy to call his supervisor or you call the Area Manager.
Meter connections are normally undertaken by a contract meter company these days, not the DNO...
