Electrical question

globalds

This one is very similar to the plumbing question I posted earlier.

A relative has had a conservatory fitted and some new sockets have been fitted.
These sockets are either side of French doors and the wire has been taken across the threshold by just cutting a 12 mm deep trench( looks like done with angle grinder) and the cable laid into the trench.


The plan is to pour some self levelling down and then tile the floor

Question:
Should the cable have been fitted into some kind of conduit ..it just seems a bit basic when I look at it.

I can get some photos if needed but will take a while.

As for code I'm unsure but:

If something goes wrong in the future do you want to have to rip up tile and chip away cement to replace the cable?
Personally I'd lay the conduit and run the cable through it.

Cement and SLC(???) can affect cables and shouldn't be laid directly onto them. The cables should also be protected to prevent breaking them by accident and electrocuting oneself.

It might well break building regs as it is.

Laying cables directly into a wall or floor would not conform to BS7671 Wiring regulations. Mechanical protection by metal conduit or capping is required as would rcbo protection.

The sockets being as they classed as additions should have been fitted by an approved electrician and part p registered, as it would be classed as notifiable works under building regs.

Since when has adding sockets or a spur to an existing ring or radial circuit been Part P notifiable?

Actually, and correct me if I'm wrong, I'm sure any 'competant person' can do new electrics in their own home, but any new work is required to be checked by an approved electrician and part p registered.

However, finding a part p sparky to check your work is not the most cost effective and easiest thing to do.

What does "new" mean?

Additions.

I'm not a sparks, just going on what a sparks has told me in the recent past.

As for 'new', I built my own extension from start to finish (well, almost finished), did all electrics, got a sparky to check and issue certificate, cost an arm & leg for sparks.

Conduit and single core cable should be ok.

Ahh OK. Don't think he's right in an all embracing way but lets see what the answer is to my question in the post immediately above.

Mmm - sparks should not have signed of on any installation he did not design, install and test himself. Naughty sparks! Doubly naughty for charging you an arm and a leg too.

Thanks for all the replies so far.
Busy day so only been back in for a bit.

I have some pictures ..Hopefully they will be in this thread if i get it right.

not great quality but you should be able to see the way the cable has been laid.








socket fitted here at side of door.




There is vinyl on the floor at the moment.This will be tiled.

Hope this helps.
