Advice on garage supply

[Sparks321]

Hi i'm looking for some advice, i have been to look at a job to wire a garage. In the garage will be 3 double sockets and 3 lights. What my idea was is to run a 6mm 3core swa from a non rcd protected way on 40amp mcb to 40amp rcd double switch in a 2way garage unit which will be feeding a 20amp radail and 6amp lighting circuit. The length of the swa will be approx 22m run under the floor cavity and out to garage.

Have I missed something here? I’m expecting I see a Fender if some sort....

Do you have a Reg number? or are you quoting a fictitious NICEIC reg?

In fairness to them Pete, I've never seen them state that, e.g.
Supply to a detached outbuilding | Technical advice by NICEIC - https://www.voltimum.co.uk/articles/supply-detached-outbuilding

@allen dickens you may be confusing that with the requirements of some DNO's, who might refuse to connect such an install?

The only thing is if the supply is PME then the regs say you should not import an earth therefore you should use an earth stake outside the garage i don't understand why but it is a reg.

So lets ditch a perfectly good supplier earth and install a twig ............. er no

Anyway no such regulation exists in bs7671

Seem to recall a thread of numerous pages arguing over the terminology of 'exporting' or 'extending' the equipotential zone.
