Supply to outbuilding (Shed)

[manos]

I think they put it in the diagram to illustrate that after the fuse you can put outlets and loads, all being protected by that fuse. You mentioned the European method of a new circuit from the CU - that's what is done here too. The diagram is just the minimum, a low cost alternative with lower power and perhaps a higher chance of tripping a house circuit .

It is not easy to supply the sed from the house CU that's why I am doing this low cost alternative method. The shed is going to have a light and a double socket. I do know if there is a problem in the shed my RCD is going to trip in the house. If I have this problem in future (hope not) then I have to find a way to get power from house CU with the correct cable, MCB and CU (including RCD) at shed and take power before the house RCD so no tripping the house RCD.

BS7671 is the same for domestic as it is for industrial, which he has passed the exam for.

Not really an exam is it, more an exercise in how to read a book, although you do get a certificate at the end.

Good evening

I am an electrician from abroad, I have my 17th edition pased in UK and I am working as an electrician in industry since 2012.
I would like to power my shed with a 2.5mm Armoured cable. Can enyone tell me if I can do it as described in digram below.
Do I need the socket outlet after the Switched Fused Spur.
If not any sugestions ?

You drawing (which is well done by the way) shows a 16 Amp switched fused spur, not possible 13mp is the max.

what could be done is instead of a FCU, fit a 16A MCB in a small enclosure.

Fused spur is 13amps sory for my drawing mistake

 

[Pete999]

Fused spur is 13amps sort for my drawing mistake

That's OK no need to be sorty

I have edit my sorty with sorry

what i meant with my post was that you'd rarely see something like lighting being fed from a RFC via a FCU in an industrial situation. the regs. are the same, it's the practical aspect that varies. usually something that is common in the domestic sector may never be seen in a factory.

Well in my job they asked us to put led lights at the output of all machines so The can check the products. All the lights are fed from inside of machine 240V and there is a switched fused spur 3A before the light.

which tere should be. the down rated fuse is to protect the smaller cable feeding the light/s
