the regs state that cables need to buried at sufficient depth (usually taken as 600mm)
That's if you bury them, iirc. They don't have to be buried.
IANAE, i dont have access to BS7671 etc...

Oh for sure. I'd happily have them in the air, or surface mount on the ground (albeit with the galv conduit as extra mechanical protection to stop it getting kicked when he goes between the shed and cabin to store wood there).
This issue lies with his insistence on burying them. I think I'm going to suggest the chase + conduit, with no backfill idea. So the result will be flush, but not technically buried.
I'm not registered (christ, it's my first job as a spark), so I'll have to get it signed off by someone else, so don't want to do anything that'll raise eyebrows.

Electricians - burying cable. I'm wiring up a cabin, powered from a small DB in a neighbouring shed (which was wired in with the intention of including the cabin and its supply in the future). I'm going to supply the cabin's DB with SWA running out of the shed and into the cabin.
The shed and the cabin are less than 2ft apart. They both sit on a formed concrete slab. My question is about how I should arrange the cable run. The owner (father in law), wants to chase a groove into the concrete and run the cable in the chase but the regs state that cables need to buried at sufficient depth (usually taken as 600mm), so I've told him that's a no go.
He isn't keen to have the cable in the air. Would it be reasonable to put the cable into galvanised conduit and put that in the chase instead? I guess if I chase the concrete but don't fill it back in, it's not technically buried, although I'd still want the extra mechanical protection of the conduit.
It's a bit annoying as I can't seem to get through to him that him "having a think about it" isn't sufficient grounds for deviating from the regulations - but that's a separate matter for the rant thread...
