Hello All.
When I started building my own house in 1985 the idea was to have one electric board supply cable feed our main house with a second supply fed to our garage/flat .
The electric board supplied the 200Amp single al core swa cable, I laid it to the house then another cable from the house to the garage/flat.
What we ended up was only using the main supply to the house (100Amp main fuse 80Amp meter).
Now I'm getting to the stage of fitting out the garage/flat I needed a permanent supply instead of the temp one.
Talking to our electric supplier and asking about a second meter/supply for the flat, after talking it through with them they said use that underground cable that goes to the flat and run it from our supply side and it will be cheaper in the long run.
From a 'Henley block' I will feed into a 100amp isolator > 63A mcb then use the above underground cable to the garage/flat.
At the garage/flat end (15M away) from the underground cable > 100Amp isolator > Henley block.
Then
One pair tails will feed the flat cu.
Another will feed the cu in the garage.
Another pair of tails will feed to an isolator and 40A mcb to a temp supply to my workshop via an underground plastic duct 40M long, (until I can put in a permanent feed to my workshop from another direction from my house.)
I have some 4mm single core Butyl cable and was thinking of putting in two pairs in parallel (joint capacity of 60A). then in the workshop >40A rccb > cu etc.
Comments please.
I will talk about earthing later because the auto saves has lost half of my post and it's late and must get to bed.
