Advice on outdoor wiring system please

[msw109]

I have a detached stone outbuilding about 18 inches from my house which has a single feed to a metal clad switch. I have no idea where this cable runs from apart from it is protected by steel tubing at 7 feet from the house to the outbuilding.

I wish to add 8 outdoor lights rated at 35w each on a cable run of 35m. 2 IP65 double sockets on a cable run of 15m and (eventually a single supply for an electric gate with a cable run of 40m) and 2 outdoor security lights PIR total 300w rating with a cable run of around 10m.

Can I do anything with my 2.5 T/E supply to the switch in the outbuilding to supply this set up, or do I have to start again form my CU with a fresh cable run?

Ta....

Yeah.....I am Part P qualified but not electrician as job... Someone will be employed to inspect and test all work done

what current do the gates need?
40m run to gate, will encounter some voltage drop

I havnt give it much thought yet as its last on my list of jobs but form what I can see they are about 2 amps

furthest away, will require VD calculation, so need the information.

That is not the same as notifying the work.
'Part P qualified' is a meaningless statement.

I am Part P qualified

Part P is one of the parts of the Building Regulations, not a qualification.

What sort of worthless fraudulent piece of paper do you have which misleads you into thinking that you know anything?

Someone will be employed to inspect and test all work done

Employed by whom?

If not by, or by the direction of, your LABC after you've notified in advance of starting the work then you are truly in the realms of "it doesn't work like that".

I am aiming to summise what sort of work this will entail. I will be buying the materials and running cable etc retrospectively due to decking being built and landscaping, then an electrician is will be on site to do whatever he needs to do.

Unfortunately for yourself it doesn't work like that. And if you're 'Part P qualified' you should know this.
The electrician who signs the Electrical Installation Certificate and notifies your LABC will need to be involved in all three stages of the process. They being the design of the circuit, the installation and the testing.
You may be able to do some of the grunt work like burying the cable etc but that is for him to decide.
So get the electrician in now - get him to do the calculations regarding voltage drop, cable size etc and agree with him the best way to move forward. Pointless asking us here since we will not be signing the EIC.

Thanks for all your advice..I will be talking to my electrician tomorrow

I bet he's back on here tomorrow - the electrician's bound to be on holiday.

I wish to add 8 outdoor lights rated at 35w each on a cable run of 35m.

allow 100W per point or actual load if greater?
