garage supply

[peter68]

HI
Could anybody please advise me or show me a wiring diagram for a supply into a separate garage.
I have a distribution box for garage but it came with no diagram or instructions. Not sure what latest regs are as I retired a few years ago.
I attach a picture of unit I have and any help would be greatly appreciated.
thanking you all in advance
Granddad Peter

Looks like you just have a supply into a small garage unit via a flex?

Black on earth looks wrong instantly. I suspect that alone is a no-no!

Also it appears you have two "lives" connected up, but only one (obvious) cable entering from the bottom? Are they supposed to be the supply L & N as it kind of looks that is how they are wired?

Your safest option is to get someone in as this is not looking like a happy ending here.

Doh! Realised you have a 3 core wire, with Brown/Grey/Black phase colours. But no green/yellow sleeve used on E, or blue for N indicator.

Is that an armoured cable entering from below? If so it should be on a proper gland and that would provide the earth (maybe in parallel with one of the copper wires as you may already be planning, for a lower impedance).

The wire also looks very thin. What size is it? What sort of supply protection do you have in place?

Do Not make it live as it looks very dangerous. get a spark to look at it

You say you retired a few years ago Peter, but you don't say from what.
