Advice on fixing this outside mess

[RDB85]

Basically I’ve attended a friend house who asked me to see why his power to his sheds had stopped working. Any help or advice on fixing this mess please

What's the mess? Not seeing it

 

[westward10]

Is that the reason it has stopped working?

Pretty much due to water ingress. Any recommendations on how to fix it and neaten it up.

So is RCD tripping?
Obviously cracked box, SWA not earthed this end, and B32 possibly feeding two radials (or is it a RFC?)

All I'd care about is understanding the reason why it doesn't work, and then whether the incoming SWA is sound. IR test it, continuity test it. I'd assume the other end is a fuse or MCB?

Then I wouldn't want to do anything other than start again. From what you've shown I've two instant ideas:
You could fit a little IP65 CU, re-terminate the SWA into that (but earth it), and fit a couple of B16 RCBO's, one for each shed.

Or you could re-terminate the incoming SWA into a galv besa box, or resin joint, extend the SWA and and fit a little garage CU inside the shed.
He could have some lights then as well.

Yes the RCD has tripped. It’s feeding two radials of 4mm 3 core NYY to each shed. Which has its own light, socket and FCU. The other end of the cable is a 40a MCB.

I’ve got a Wiska 1010 box and a Vent Plug, if the SWA is no good I may replace with NYY so it’s all the same cable. Would this need to be earthed with an Earth locking nut on that end?

Also replace the connector block with 222 Wago?

You don't replace a cable so it matches the other you replace it with a suitable cable. NYY-J does not need an earth lock nut. I'm not sure you are experienced enough to be undertaking such things without supervision.

As bad as that lot looks, the reason could be downstream of there. You need to IR test the two radials in turn.

if the SWA is no good I may replace with NYY so it’s all the same cable. Would this need to be earthed with an Earth locking nut on that end?

Does the SWA have a cable route where it would otherwise need RCD protection at source? You may need to consider this before changing cable type.

Wagos? Yes!

What I’m saying is if the SWA is no good. I’m going to replace it with NYY-J Meaning it’s the same cable type used throughout the installation.

The SWA runs into the Garage Consumer unit. It’s on its own MCB. What would be best used to connect the two boxes together. Something like a Brass Compression Gland.
