Do you need an earth rod for an outbuilding?

[Josh95]

10A for the sockets then!

Hi Josh, I'm thinking this design may be affected by reg 434.2 and 434.2.1(i) which seems to limit length of an un-fused spur to 3m.
I would add a new radial to CU. Cheers.

 

[Josh95]

Its not un-fused.

 

[Taylortwocities]

Fed from a spur on an existing ring inside the house

So there's a a 13A FCU from the ring final that the SWA connects to?

So it seems, probably doesn't need a CU just fit socket/s straight to it with a FCU for the lights.

Are there any extranneous conductive parts in the shed.? What type of shed isit?

 

[Taylortwocities]

That depends on if the circuit in the house is RCD protected. If not then a mini 'garage' CU may be preferable. But we do not know enough to guess. As posted several days ago.....:

So much more info required josh!

 

[Josh95]

Its not rcd protected in the house thats the reason for the cu in the shed.
No extraneous conductive parts & the shed is made of wood.

If the ring in the house isn't RCD protected then I'd make the FCU an RCD unit so that the SWA is RCD protected as so is the shed.

A small CU in the summer house with a 10A for the sockets and a 6A for lights would then be ok.

That then opens the question of: Should the shed CU be metal...?

If remote from the house and not part of the habitation then possibly no but as its wood its flammable.

 

[Josh95]

Would an earth rod be needed ?

 

[Taylortwocities]

So there's a a 13A FCU from the ring final that the SWA connects to?

 

[Josh95]

Yes thats correct.

 

[Taylortwocities]

Ok, I would put garage RCD protected CU in shed. 16A radial for sockets. 6A for lights.
Export earth from house.

 

[Last plumber]

And maybe 5 would understand why their doing it which way!

Yes big spark. You're 100% right.
The trouble is, all electricians give a very convincing argument for either method.
So it's finding out which half of the discussion, those 5 belong to.
Especially when this is this first time I have had to think through this particular issue.
I wasn't trying to insult anyone.

10A on skts as the FCU will have max 13A fuse.

Have you put a low price in then realised to do it proper will be more expensive?

Josh Josh Josh i have looked at your thread and have joined to reply to how unhelpful and belittling the support some people give. but others are there to help.

I'm not sure .I've always put Rod in but saw an article and it said it could create problems
